Thank you for reporting this.

Can you give me the output from the sw_vers command in the terminal (it gives the precise macOS version), and tell me which PPC computer you are using to test this? Maybe there's an issue with bigger screens or dual monitors (at the moment I only have PPC laptops), so the more context you give the easier it will be to work it out.

We've also just released a new 2.7.0 release for PPC, does it fix the problem, by chance?

Also, please make sure that you have the "Millions of colors" setting enabled in your OSX system preferences.

comment:4 by jamie-marchant, 2 years ago

Yes the "Millions of colors" was the problem. I had it set to Thesonds.

I am still getting this in 2.8.0 and think it's a bug because the error only shows up on a terminal instead of showing a dailog box that says "this software requires millions of colours." This is what other software on the OS would do.

Replying to jamie-marchant:

You're right in reopining this ticket; from a user perspective, it's hard to know that this setting needs to be changed. I'm also aware of another user on Twitter reporting this behavior.

I won't have the time to look into this and fix this for the moment, but if someone wants to provide a patch to improve this, it is of course welcome!

I can't get Scummvm to compile on my old Mac, so it can't be me.

comment:10 by jamie-marchant, 8 months ago

I am not sure where to put this but this still happens on version 2.8.1.

Hello,

I had a bit of time to look into this again.

@jamie-marchant: I saw that DOSBox 0.74-3-3 (see the universal .dmg file at <​https://www.dosbox.com/download.php>) had the same problem, when setting the monitor to thousands of colors. Do you confirm this?

After some investigation, it looks like it may be an SDL regression from its 1.2.15 release, and not a ScummVM bug (i.e. you should be able to start ScummVM, even with a 16 bpp monitor, because most games support this, anyway. So it's not really a matter of adding a warning screen.)

I couldn't fix this for the official ScummVM 2.9.0 OSX PPC release, but I've made a test .dmg where I just relinked the 2.9.0 release against a patched SDL library.

​https://github.com/dwatteau/scummvm/releases/download/v0.3.0b/scummvm-2.9.0-macosx-ppc-PATCHED-SDL-trac-bug-14262.dmg

@jamie-marchant: Can you test this patched release on your machine, with all monitor settings and games you can try, and report back any issue? If it's OK for you, it's going to be included in the next 2.9.1 or 2.10.0 release.

Thanks!

(technical notes about the SDL patch: I've removed the check at <​https://github.com/libsdl-org/SDL-1.2/blob/0237f339e6bec39c56e1364787fabdb0245d478f/src/video/quartz/SDL_QuartzVideo.m#L291-L294>, which was added by upstream in commit <​https://github.com/libsdl-org/SDL-1.2/commit/991bbb91c8cff091c7c1aee216e02949080756b6>, only part of SDL 1.2.15 and later. It looks like the latest SDL 1.2 releases were more likely to add regressions on earlier OSX.)

Yes indeed Dosbox has the same issue and the ​​https://github.com/dwatteau/scummvm/releases/download/v0.3.0b/scummvm-2.9.0-macosx-ppc-PATCHED-SDL-trac-bug-14262.dmg, works perfectly. Thank you very much.

Cool, thanks for testing so quickly! And sorry it took so look to fix that -- I've been very busy for the last two years, but it's getting better, now.

I'm marking this as fixed, then, and the next official OSX PPC releases will include this SDL patch by default.

Don't hesitate reporting any other issue that you may encounter on OSX PPC, I'm very interested in them :)

Cheers
