For example i tried Space Quest IV.5, on both win32 and amigaos4 : on win32 it starts fine, on AmigaOS4 it bring such an output:

It does not matter if i use Opengl, OpengGLWithShaders or Software renders, all the same.

Which point out that it can be Endian issues (especially that phrase Block: 'Main', expected to end at offset: 30788, finished reading at 33085..! sounds like bad reading from/to memory)

I can't reproduce the room74.crm error on my old PowerBook G4 (big-endian too). It's incredibly slow (well, it's a debug build without optimizations) but the game looks playable.

However, it does crash when I quit the game to return to the launcher. It also crashes when loading a savegame I've made in the first scene. It looks like it always produces corrupted saves there.

Attaching some GDB logs below (gzip'd, since Trac issues slow down when I attach big .txt files to them).

gzip'd savegame which causes the crash. May have been corrupted when written from big-endian? sq45.000.gz
