The game was developed with openGL and libSDL libraries, what mean that without opengl drivers (like in case with aos4 and radeonHD cards) game will not works, or, only via software renderers like Wazp3D (untested).

AROS user who not have HW accelerated ogl drivers, will automatically switch to softpipe version of opengl (done by aros itself), which are slower, but as i386 HW are fast enough, such simple game should works fast on software rendering pretty fine.

All the differences which was done for amiga/amigalike oses its changing of amiga pathes (PROGDIR: and stuff), and one small fix at the exit (adding of missing SDL_Quit();, which looks like workorounds by linux/win32 sdls, but not by SDL on any of our oses).

Icons done as plain .png (to avoid mess with different formats). So, for aos4 you should have png icon.module installed, for morphos all come by default to support png icons, and for aros some kind of png-icon support should be used as well (if present).
