[Scummvm-devel] 'gob' engine & 8bpp

Yes, I'm aware of the fact I don't get away without some coding ;)

By the way, am I right in my assumption that if I wanted to support 4bpp
(EGA) or even 2bpp (CGA) modes natively, I'd need to change rendering code
for each of the engines to support that? I.e. that even if a game is purely
EGA, the engine renderer renders into a 8-bit chunky buffer?

And yes, DG is right, the platform we're talking about is Atari/FreeMiNT,
it has 1/2/4/8 bitplane palette based modes and a 16-bit hicolor chunky
mode. Sorry about not mentioning that earlier.
