Grey is what the subject line says: a FPS, running at an acceptable framerate, on a Commodore 64, without a Raspberry Pi or other hardware to help it out. Here is its thread on Lemon64. Have a look (24 minutes):
How is it possible? Well, it’s not running 60fps for one. Updating the whole screen in one frame on a C64 is hugely challenging, but fortunately FPSes can look satisfactory running at slower framerates. It’s not Quake-level graphics, or even Doom, it’s more like Wolfenstein 3D in ability, and it’s confirmed that it uses that style of raycasting. And on top of all of that, it doesn’t use hi-res resolution, which would be really slow on an unmodified C64. It seems to use character tiles to fake a kind of low-res display. But when you’re trying to get a game running on a 1 MHz machine with 64K of RAM, tricks and shortcuts are not only necessary, but rather laudable. What a hack!
This is a work-in-progress, with a demo of the game available in a recent Pateron-available issue of Zzap 64. No source code is available yet. Let’s hope for continued development!
