Romhack Thursday: Simon Belmont in 8 Eyes

On Romhack Thursdays, we bring you interesting finds from the world of game modifications.

There aren’t many game series with the reputation that Castlevania has. While it’s always been very popular, the stature of the original game has only grown over the years, and it’s now seen as one of the very best games on the NES. We’ve talked about it here before, and about how badly the creator of one of the best-designed games ever made was treated by his company, but we’re not here to talk about sad things today.

You’d think Castlevania would have more imitators, but there aren’t as many as you’d think there would be? It has specific and definite ideas, some of them not obvious to a random player. Simon moves slowly and jumps stiffly, but it’s clear with repeated play that not only is the game designed around this, it’s even a better game for it! It’s a good example of how reducing a player’s abilities, relative to Mario-standard, can actually result in better play.

Some of the enemies were changed too. I don’t think this enemy was a skeleton in the original?

One of the few definite Castlevania clones that come to mind is Thinking Rabbit’s 8 Eyes. It could not be more obvious while playing it that its designer played a lot of Castlevania; its hero Orin’s movement is nearly an exact match for Simon Belmont, and it even has staircases that he can climb and hidden items buried in the walls.

It’s not as good a game as Castlevania, definitely, but it has its own ideas, and I respect it for adding some unique features. The player can determine what order the first eight levels are played in, and every time they finish one their attack power is upgraded. It has devious level designs that don’t always map cleanly on paper. It has a player-controlled drone character in the form of a falcon that can be deployed, and then flies around on its own, and can be commanded to attack and return and even has its own health. Most interesting of all, every level has hidden with it a clue, a piece of text that must be found and used at the end of the game to solve a logic puzzle to finally win.

Here’s one of those clues! Unlike the clue books in Castlevania II, every one of these is essential to solving the final puzzle.

There’s a lot of cool ideas in 8 Eyes. If it had some more design and development work put into it it could have been seen as a later highlight of the system. elbobelo has, for over fourteen years, been at work on a huge hack to put Simon Belmont into the game. In a forum thread they started long ago they mentioned that, while work has slowed, it’s still going. They haven’t issued a public release since an old beta in 2008, but there’s enough present in it to make one wonder how it’ll play when it’s finally released.

Here’s one of those clues. BTW, it’s not well known that 8 Eyes actually has eight quests. The game is mostly the same each time, but the logic puzzle is different!

Fortunately, the 2008 version of the hack keeps the cool ideas that 8 Eyes contributed, and it just adds features from Castlevania I and II. It keeps the falcon, the diabolical levels, and the clues and game-ending logic puzzle. Gone, however, is the player’s sword, replaced with Simon’s whip, which is a vast improvement. In addition to the falcon, Simon can find his usual subweapons, which don’t replace each other but can be switched between with the Select button. It doesn’t make the game too easy because 8 Eyes was a very difficult game. It just makes the challenge more reasonable.

Most levels have at least one puzzle that requires you to release the falcon somewhere on screen to fly around while you run to the door, so you can attack the switch with the bird then run in the door before it closes.

Best of all, it also keeps 8 Eyes’ weirdest aspect: after you beat each boss, you sit down and have tea with them! In the original the tea was brought by one of the boss’s flunkies, but in this hack one of the skeleton enemies brings it in. It’s surprisingly adorable!

Many more games should show you having tea with the level boss after you beat them!

itch.io: Squirrelativity

You’d think there’d be more unique types of puzzle games than there are. For every genuinely new idea there’s a dozen Tetris-likes. Even genuinely unique puzzle games often have another game as a basis, like how Baba Is You starts from a foundation of Sokoban before launching off to the depths of Ridiculous Space at Ludicrous Speed.

I can’t claim to have comprehensive knowledge of all kinds of pre-existing puzzles, but Squirrelativity seems unique enough to be really interesting..

Made for Ludlum Dare 52, it’s a free game with only 15 levels, but they’ll have you mystified long before you reach the end.

One team of squirrels has a tree growing up from the bottom of the board, the other has a tree growing down from the top. How it grows, though, depends on how you draw their branches. The bottom tree’s branches can only go up, and the upper tree’s branches can only go down. Each set of squirrels can only broach their own branches.

In the middle of each board there are a number of green seeds. A color of fruit will grow out of the seed, depending on which tree touches it. However, each squirrel’s tree makes the fruit that the squirrels of the other tree likes. It also drops down according to that tree’s gravity. That is: the blue squirrels’ tree grows up, and produces red fruit that drop down, and the red squirrels’ tree grows down, and produces blue fruit that drops up. Got it?

The screenshot I took demonstrates how the fruit falls. Neither tree can grow branches through a space containing a branch from the other tree, and each level can only end if you both get all the seeds, and each team of squirrels get the same number of fruit as the other. The delicate balance of squirrel power must not be overturned!

Kimimi on Korokoro Puzzle: Happy Panechu!

Kikimi the Game Eating She-Monster’s blog is on the short list of blogs we watch for interesting stuff, and she’s found a winner this time! Korokoro Puzzle: Happy Panechu! is a Japan-only GBA puzzle game that uses a similar kind of tilt sensor as found in Kirby Tilt N Tumble.

It’s a game that involves moving colored blog creatures around to connect them in groups of four or more to clear them out, which sounds pretty typical at first. But doing this also creates bombs that you can also connect, to make them into bigger bombs, and clear out larger fields of clutter as you do so, as voices proclaim things like “So happy!” and “Mega happy!”

The tilt sensor comes into play in that it allows you to determine from which side of the screen new objects enter from.

Korokoro Puzzle only got the one entry, but we have it from Kimimi’s that it hides a whole lot of gameplay within its little rectangular case.

Cavern Sweeper

I’m a fan of the work of Finnish game creator Arvi Tekari, aka Hempuli. He burst on the scene three years ago with genuine indie hit Baba Is You, which somehow continues to receive updates. (If you have it and haven’t played it in a while, you might want to take a look. It just might have a lot more puzzles in it than you remember.) We’ve also linked to his Finnish translations of the Super Mario Bros. manual, and his parody game of his own work Baba Is You XTREME.

Somehow though, he keeps making interesting new things! Most recently there’s Babataire, a variant of Spider Solitaire that uses Baba characters for cards (it’s fun!), Babataire Ex, a variant of the variant that also uses Baba Is You’s rule-modification mechanic (and that, honestly, I can’t make much sense of), and Cavern Sweeper.

Cavern Sweeper is really good! It’s a generalization of Minesweeper where the mines not only have different values, casting varying amounts of danger into the adjacent squares, but where, on harder difficulties, different kinds of mines can even have differently-shaped danger zones.

In the easiest version, all monsters have a diamond-shaped peril region around them with a value from one to three. The number in a space is the sum of all the danger spread into them. Harder versions also add slimes, which have the traditional square-shaped Minesweeper danger zone, ghosts with plus-shaped areas, and optionally serpents with X-shaped zonas de peligro.

To make up for the added uncertainty, you’re granted two additional helps. First, as you mark spaces (you must select the proper kind of monster in the space for it to count), the numbers are subtracted from the nearby regions, decreasing the chaos around it, and any impossible situations are marked for you. And you’re allowed two extra misses before you’re actually in danger of losing the game.

Cavern Sweeper is a fine addition to the genre of Minesweeper variants, and I rather think I prefer it to the original.

Remember EYEZMAZE and GROW?

There was a time when these short Flash games were the toast of the internet. There is very little cultural memory online for anything that isn’t absolutely huge (and almost no quality control over the things that become huge) so no one talks about GROW anymore, or its Japanese creator On, which is a tremendous shame.

EYEZMAZE took a tremendous blow when Flash shut down. I really hate how people generally accepted its demise as good and necessary when it obliterated so many great things, like Homestar Runner’s original website, that are only now sort of becoming available again. There were serious problems with Flash, it’s true, but not all the reasons it was shoved out the airlock were good ones. Fortunately On has converted many of his games to work with HTML5.

The art is great for its own sake, but the games, available by clicking on the icons at the top of the site, are the highlights, and foremost of those are the GROW series. I was going to link them individually here, but most of them are GROW in some form of other. You should probably start with the first.

The object is to figure out the best order to click on the various items to add to the GROW planet. Every time you add something, things that were already on the planet may “level up” depending on the other things that are with it there. Some things being added too early may harm the development of other things. Usually there’s one specific order that will result in a perfect score (and an animation that goes with it). Figuring it out, using the visual clues from your failed attempts, will usually take many tries, but a run through only takes a couple of minutes at most. All off the GROW games take this general form, although most of them aren’t as complex as the first.

Bitrot has not been kind to GROW. There was an Android version of Grow RPG that appears to have succumbed to Google’s awful app culling policy, where if something isn’t updated, for whatever reason, in a certain time they just delete it. (Not nearly enough has been said about his hostile this is to software preservation. It’s horrendous.)

On has had health struggles over the years, which have interfered with his creation of new amusements. He still seems to be up and active though, and we hope he continues creating both his games and his art for a while to come.

Video: “Bub” Plays Pac-Attack

“Bub’s Broadcast” is a YouTube channel put out by Taito, mostly to promote various Taito properties in Japan. “Bub” is a mascot character based off of Bub, a.k.a. Bubblun, from Bubble Bobble. It’s low-key, yet entertaining, fare.

This particular video is of interest though because Bub steps outside his usual stomping grounds, and plays Namco’s Pac-Attack, that Tetris-style puzzle game where you have to create paths out of falling blocks to guide Pac-Man to eat ghosts.

It’s in Japanese, but there’s English subtitles, and of special interest is that Bub reveals some possibly-unknown codes for the game. If you point at Hyper difficulty and hold L and R down when selecting it, the game will begin at Level 300 instead of 100. And if you hold Down and Right on the control pad while also pressing L and R, you begin near the highest possible difficulty, at level 900! Also revealed is that, if you charge up the Fairy meter all the way and a fairy comes out, but you don’t wish to use her ghost-clearing power, you can hold Up and press B repeatedly to cancel it, causing her to fly away and giving you 10,000 bonus points. It’s always interesting when these unknown game elements are revealed long after the games release!

The World Record In Hatetris

Let’s start by getting you up to speed. It’s one of the most well-known video games in the whole world at this point, but people who’ve lived under rocks might not know about Tetris, the block falling puzzle game created in Russia and popularized first by Spectrum Holobyte, then by Nintendo. Favorite game of both diehard Japanese arcade players and Steve Wozniak.

Tetris blocks, a.k.a. Woz’s Bane

While the increasing speed and rising pile are what directly end games, a lot of the difficulty of Tetris comes from the pieces that are generated by the software. Famously, it’s known that completely random Tetris is doomed to failure, that it’s been mathematically proven that there exist sequences of blocks that are unsolvable, but aside from that nearly all sequences are survivable.

One thing that can help a player survive is the sequence of the blocks that are generated by the game, which is really getting into the weeds. A consistently varied collection of pieces helps out a lot. Early versions of Tetris just picked any block, and sequences of the same piece could easily happen. Recent years have seen an effort by the official stewards of the game, The Tetris Company, to standardize it, and one of their edicts is to use a “bag” system, where the game tries to ensure that all pieces will appear over a short period of time, to try to keep the game fair while still acceptably random-seeming.

At the other end of the field, Hatetris is a fan-made form of Tetris that seeks to increase difficulty by picking the least-survivable block, the one least able to fit in with the rest of the bit. (It’s not the only such version, another is Bastet.) Casual players usually find it impossible more than one or two lines.

Warning sign of obsession: making graphs

Yet recently there has been surprising progress in surviving this worst-universe version Tetris. Getting the World Record in HATETRIS explains the work done to maximize scores in this version; the current record is 86 lines. Helping their work is that the Hatetris isn’t random at all, but actually completely deterministic. The piece that must stack the bin the highest is always chosen, so it can be predicted and, to some extent, accounted for.

And with an ocean of computing power out there now, sloshing about over everything, it was probably only a matter of time that someone would look into optimizing adverse Tetris. What, I ask you with growing concern, is next?

Arcade Mermaid: Amidar

Arcade Mermaid is a recurring feature where we look at weird classic arcade games. The word weird has many meanings; sometimes it means bizarre or ludicrous, but sometimes it means of a really unusual design.

Our game this time easily fulfills multiple senses of the word. Konami’s Amidar was released in 1982, putting it near the end of the arcade boom in the US. It still came out early enough to get an Atari VCS/2600 port from Parker Bros., the source of many of the better arcade ports of the time that didn’t come from Atari or Coleco.

Odd Boards: Gorilla and Spearmen

Amidar‘s game world is both abstract and evocative. You’re a gorilla, tasked with collecting all the dots on a board made of lines, while evading hostile spearmen called “Amidar” (plural) and “Tracer.” Unlike as in Pac-Man, the playfield isn’t a maze as it is a bunch of adjoining boxes, with you and the enemies walking along their border lines.

People who have played a lot of Mario Party might find something oddly familiar about this layout. We’ll get to that.

When you collect all of the dots around one of those boxes, it fills in with a solid color. These boards you can play somewhat like Pac-Man. There are differences, though. The “turn the tables” mode that lets you attack your pursuers activates when you fill in the four squares in the corner of the screen. You only get one such period every level, and it takes a lot of effort and some foresight to achieve it. If the last box you fill in is one of those corners, you complete the level immediately and don’t get any bonus points for chasing down the enemies.

Even Boards: Paint Roller and Pigs

There is another kind of level in Amidar, however, that plays similarly, but with a significant difference. In these, for some reason, you’re not a gorilla but a paint roller, and you’re avoiding not natives but bipedal pigs. No reason is given for the change of graphics, although they’re still called “Amidar” and “Tracer.”

In these alternate boards, each of the rectangles has a number in the middle, which is a bonus score you earn for filling it in. On the gorilla boards, you only get points for collecting dots and capturing enemies during the attack period. Here, you get points for surrounding boxes and capturing them, so these score a lot better.

The trade-off, that makes these boards a lot harder to complete, is that you can’t just collect dots however and expect your progress to stick. There are no dots.

Instead, you have to extend the colored border away from already-colored lines, surrounding boxes one at a time. If you leave the border of the box you’re currently coloring, your progress will disappear! You’ll have to go back to one of your established lines and start over. Because you can’t just color them at any time but instead have to extend your territory out to them one box at a time, it’s a lot harder to take advantage of the attack phase granted by coloring the four corner boxes. It’s a lot harder in general. Most games end on Pig boards.

You have final aid to help you get through each level. Each board and each life, you get three uses of a “Jump” button that allows you to slip by the Amidar and Tracer. But, in keeping with a game where you alternate playing as a gorilla and a paint roller, the Jump button doesn’t allow you to jump over enemies. Instead, it causes the enemies to all jump, allowing you to pass beneath them.

Amidakuji

After you’ve played a couple of games of Amidar, you might catch on to an unusual property of the enemies. They don’t chase you. The have a specific route they follow through the board. Pac-Man may have patterns you can use to evade its ghosts, but Amidar makes the pattern followed by the enemies explicit, and the whole point of the game.

The motion of the normal enemies is entirely deterministic and uncaring of your location. Instead, they move in a specific, meandering pattern. They actually follow the routes of the Chinese “Ghost Leg,” or as it’s called in Japan, Amidakuji lottery. (You see? Amidakuji? Amidar?) They move down along vertical paths until they reach a horizontal intersection, which they will always take and then continue downward. When they reach the bottom of the board, they reverse their vertical progress, going up to reach the top again, still taking horizontal paths when they encounter them.

This is where Mario Party players might find this familiar. The Amidakuji lottery is simulated in the minigame Pipe Maze. In this, the four players are randomly arranged at the bottom of a network of pipes, and one of them must drop a treasure chest down one of the entrances at the top. The treasure travels down in the manner of the Amidar, and whichever player it reaches at the bottom gets the treasure.

The Amidakuji lottery has some interesting characteristics. It matches up each of the vertical paths at the top with exactly one path at the bottom. It doesn’t matter how many side connections there are, there will always be one way through for each path at the top.

To emphasize this, between each board of Amidar there is a bonus round that works more directly like the Amidakuji. You pick one of the routes for an Amidar to begin winding down, trying to guide it to a bunch of bananas at the bottom. Once you learn the knack of these stages it’s not hard to get the bananas most of the time. With your eyes, try to quickly trace the path in reverse, starting from the bananas.

The key to success at Amidar is focus and practice. With experience you’ll get better at figuring out where the Amidar will go in real time, and can avoid them more easily. Later levels increase the number of Amidar. Also, since a player can avoid the Amidar pretty consistently, there’s a failsafe timer in play. If you take too long to finish a level, the Tracer, which usually only moves along the outer boarder, will leave its patrol route and start following your prior movements through the level. This really starts to be a problem with Level 4. It’s good to save the corner blocks for when this happens.

Once you internalize the rules to Amidakuji, you may find yourself progressing deep into the game. I’ve been as far as Level 6! The game also has charming, melodic music in the style of Frogger. At the time of its release it was a minor hit for Stern, its licensee in the U.S., and now can be seen as a highlight of its genre.

Level 6! Notice how all the lanes at the top are blocked off. You have to squeeze by when they’re taking horizontal routes or use the Jump button to get by them.

A post-script. I searched for information on Parker Bros. Atari VCS port of Amidar, the only one made during the classic era of arcades, and found a page on the fandom.com wiki that gets many key facts wrong. It mentions coconuts: no version of Amidar has coconuts in it. It mentions the Jump button making enemies jump and not you: this is not at all evident in the VCS version. It mentions a bonus stage after every round: this doesn’t exist in the VCS version. This is one of the reasons I hate fandom.com!
