I only just discovered the world of Mac-RPGs in fall of 2022. From then on I collected every RPG I could get hold of (and was astonished of how many of these shareware games are still sold) and created a "ready to play" package with Sheepshaver and Mini vMac. It took quite some time to find the perfect configuration for every game but it was more than worth the work. I'll try MAME (I've never worked with it before). Thanks!
I didn't play Shadow Keep and Gang Wars, no. I'll definitely take a stroll to Macintosh Garden to take a closer look at these two. Some others I very also enjoy: Nethergate, Scarabs of Ra, the Mac-exclusive Ultima III-Remake, Quarterstaff, Nemesis.
