Thanks for the suggestions guys:
@AmigaJay I'll keep it in mind. They could possibly go as part of a broader "Amiga Games that Weren't" collection!
@BooBoo I came close to getting Doom to work on stock CD32 with a minimalist wad, but couldn't quite pull it off (my best attempts required 2.5mb~ for RAM). In any case I figured that configuring the ADoom source code specifically for CD32 would be a better approach.
@ransom I've had limited success with injecting music into games before, though I'll keep it in mind.
@soldierpcb Since Psygore solved the John Twiddy loader issue in Putty Squad, I'm under the impression he'll eventually do the same for Cool Spot and Global Gladiators
Body Blows AGA is HD loading anyway, no special loader needed. Body Blow Galactic AGA would require a loader though. I've added that and Shaq Fu to an honourable mentions list.
@cobe I'm sure it'll be done someday
but I can't afford to put any time into it at the moment.
