AGS: AMIGA: Black Screen/Window on start of nearly all games

[raziel-]

ScummVM 2.3.0git (Aug 14 2021 12:01:56)
Features compiled in: Vorbis FLAC MP3 RGB zLib MPEG2 Theora AAC A/52 FreeType2 FriBiDi JPEG PNG GIF cloud (servers, local) TinyGL OpenGL

I get a black screen/window and unresponsive cummVM (only reboot possible) on nearly all games that run in the AGS engine.
I have actually found only one game that will start (Space Quest IV.5), all the other game i tested are stuck at a black screen.

Not sure if it's an endian issue or something else, maybe someone with a PPC BE machine other than mine could give it a test?

AmigaOS4 - PPC - SDL/OGLES2 - BE
gcc (adtools build 11.1.0) 11.1.0

All the other games i tried never reach (or lock up before or while)

Opened game data file: xxx.xxx

This i get with one of the few games that formerly ran.
Any ideas?

I started the game with "SDL-Surface" in launcher, Game mode "OpenGL" and fullscreen

User picked target 'sq45' (engine ID 'ags', game ID 'sq45')...

Looking for a plugin supporting this target... Adventure Game Studio

I can't reproduce this on either big-endian PS3 or big-endian PowerBook G4 running Linux or OS X.

Might be worth it to test a newer snapshot?

I'll try when I get back home.

Did you try anything else than OpenGL with shaders?

Thank you for checking

This has been fixed for at least SQ 4.5.

I still get a black screen for SQ Decision of the Elders (where it just sits there filling up my RAM slowly and nothing else happening)

I also can't really test other games since i encounter an immediate crash when trying to "Add Game" (with detection being a plugin) :-(

Probably still needs to be set to Pending?

Hi raziel-! Does the SQ Decision of the Elders game still gives you a black screen on an up-to-date development build?

PR ​https://github.com/scummvm/scummvm/pull/4312 has been merged, and it should fix some AGS games on big-endian systems. The symptoms were similar to your "filling up my RAM slowly" description, so maybe this PR fixed this bug.

Will test asap and report back

Thank you

@dwatteau

Fixed.
Reported game now starts everytime and some more do too after a quick test

Thank you very much

[dwatteau]

@raziel-: Cool, thanks for your test!

Well, we still have some issues on big-endian AGS, but things are improving :) This particular fix will also be part of the 2.6.1 release.
