Got it work with 2 demo paks that were between 10 and 20 MB in size. TMNT: The missing Turtle and X-Men 1 where you play as Psylocke and Cyclops. When I realised that some of the Paks were massive and default to higher resolutions I chose some lower sized Paks (20 - 35 MB in size) and found the following worked:
1) Golden Axe: The Curse of Death Adder
2) Final Fight Apocalpse
3) Final Fight vs King of Fighters
All are fun but the first two are REALLY good! Golden Axe is supposed to resemble Golden Axe 3 and Final Fight Apocalpse plays like an official sequel with Maki and the three original Final Fight lads!
Nice game to check out if you have an 060 & AGA/ graphics card or Vampire!
With a graphics card it plays FULL SCREEN just like having an arcade machine in your house! Much better than the Amiga version of Final Fight which was awful with jerky scrolling.
