Here is a very basic port of z81 to the gp32. It’s a port by woogal of an older version because it had less files. It comes with the zx81 rom and a few games. Games are free, and noone seems to know who owns the rom anymore so woogal think it’s safe to include.http://www.gp32x.com/board/index.php?act=ST&f=4&t=17600
