Or another crazy idea -- as you might know, SimCity is done as a GEM application. Unfortunately, due to packers and who knows what it's not even compatible with Falcon (at least under Hatari) ... I suspect it uses standard VDI to draw things so maybe it wouldn't be that hard to adapt it to run under let's say XaAES in multitasking? By adapt I mean throw all depacking routines, maybe do some proper appl_init() ...
