Displaced Gamers’ series on investigating design and programming problems with NES games continues with a game that I’m surprised isn’t more notorious, Ikari Warriors. (21 minutes)
The biggest problem with Ikari Warriors is probably that it was ported by infamous anonymous NES developer Micronics, who even in their best efforts tended to produce buggy, janky messes. Some other games they made: Ghosts & Goblins, 1942, Tiger-Heli, Elevator Action, Super Pitfall and Athena. All the other problems have their root in that.
Ikari Warriors runs at 15 fps. One game frame for every four screen frames! It uses expensive multiply routines instead of look-up tables for movement! Everything is slow even accounting for that! And it tries to adapt the arcade game’s character rotation system, which supports 16 directions (even though there are only character graphics for 8 of them), and forces the player characters to rotate through them to move.
All of this overhead makes Ikari Warriors really slow and frustrating to play. Displaced Gamers not only diagnoses the problem, but even makes a game attempt to fix them. And they come to the conclusion that it has additional problems, beyond even these, and really needs a bit of a redesign to really make it playable. Ah well, it was a good attempt.
