I only have a 500 and an A1200. I guess maybe I'll write something, but it's so old. I'm writing games on the PC now. I will be doing a PC version of Starfighter.
I hope you are using SDL and OpenGL, becouse then the game should be more portable not only for AmigaOS, MorphOS and AROS, but also for Linux, SkyOS, MacOS, consoles, some PDA's and and... Oh, Windows aswell :-)
