SCUMM: Allow Amiga palette in MI1 / Loom DOS EGA versions

[CitricTabby]

First off, I love your app big time! I have managed to buy the floppy disks / CD-ROM discs (via eBay) and digital versions (via GOG.com) of SCUMM games made by LucasArts over the course of the past few years, and I physically own the DOS, Amiga, Atari ST, and/or Mac versions of almost all the games I have made digital backups via my Greaseweazle 4.0 floppy combo drive setup and/or my internal optical drive hooked up to my homebuilt gaming workstation PC with Windows 11 Pro as my full-time OS.

One thing I would like to see you implement into ScummVM is the Amiga EGA palette-based render mode for Monkey Island 1 and Loom (both DOS EGA games). I know you have that for INDY3 as well as Maniac Mansion V2 and Zak McKracken V2 (all DOS EGA), but MI1 and Loom (both DOS EGA) could definitely use it as I am not so fond of seeing sun-burnt human skin tones, as it could imply they would be suffering from skin cancer like melanoma.

Please look into it as you implement this into a future build for ScummVM.

Thank you!

I may misremeber, but I think this "trick" was possible some ScummVM versions ago, and was later removed

If your project has successfully made the original DOS EGA version of Indiana Jones and the Last Crusade to work with the Amiga color palette renderer option, couldn't you try to port said options to the original DOS EGA versions of Loom and The Secret of Monkey Island as well?

Or at least bring back that color palette override trick you mentioned to the current ScummVM daily builds.

Nice collection you have there :)

Yes, ScummVM used to let you use which render mode you wanted. The list of possible choices was reduced in commit <​https://github.com/scummvm/scummvm/commit/2fe65d95ef86433460c2c59eca9de022564c2926>, mostly because some users tried to use some impossible settings, such as "CGA mode on Mac or Amiga".

Then, the popular Amiga skin tone was allowed again as a special exception for Maniac Mansion/Zak, and then for Indy3 (Trac#15227).

I agree that we should probably allow setting this for MI1/Loom as well again, yes. I'll see if the other SCUMM maintainers are OK with this.
