M4: Orion Burger - Gfx mesh and crash on BE target

[raziel-]

ScummVM 2.9.0git (Dec 30 2023 18:06:49)
Using SDL backend with SDL 2.28.4
Features compiled in: TAINTED Vorbis FLAC MP3 RGB zLib MPEG2 MikMod Theora VPX AAC A/52 FreeType2 FriBiDi JPEG PNG GIF cloud (servers, local) ENet SDL2 TinyGL OpenGL (with shaders)

I get the attached gfx mesh in the intro (and a crash just about when the line, 'I'm on it, Boss' comes up)

User picked target 'burger' (engine ID 'm4', game ID 'burger')...

Looking for a plugin supporting this target... M4

I've made some commits in the last week which may help this, but I can't really do any further fixes since I don't have a BE system, unfortunately.

I'll sure test when I get back home.

Thanks a lot

@dreammaster

Unfortunately now i get a crash wehn trying to run the game (crashlog attached)
I'm pretty certain it's still because of some BE issue.

No graphics come up anymore, black screen

I'm not on discord, but i know one member of the team has access to a BE MAC or LINUX machine. Maybe you could ask for help there too?
I'm always willing to test BE stuff, but i'm pretty limited when it comes to coding itself...mostly test monkey here :-)

[dreammaster]

We'll have to see if anyone volunteers. Fingers crossed.

@dreammaster

@dwatteau was the kind soul who cross checked on his PPC BE machine in the past...maybe he'd still be willing to do so again?

[TrivialBalderdash]

I'd be happy to test on a G4 PPC w/ Mac OSX 10.4.11. What's the best way to get a daily build to test? I've compiled ScummVM on Linux, but I'm not very confident in my ability to correctly compile on or for a PPC Mac.

@TrivialBalderdash

thank you for stepping in

daily builds are available from the buildbot
​https://buildbot.scummvm.org/#/dailybuilds

but im not sure if there is a special ppc mac build available

[TrivialBalderdash]

Thanks @raziel-

There's isn't a daily build for PPC Mac that I could find.
I'll reach out to dwatteau / Tsomi for advice.

what about this?

[raziel-]

ah, sorry, release doesnt support syberia yet

[dwatteau]

Unfortunately, my PPC systems are now in their cardboards before I relocate, so it may take me weeks (or more) before I can have a look at this, but I'd suggest following this guide for big-endian tests, instead:

​https://wiki.scummvm.org/index.php/HOWTO-Debug-Endian-Issues

It's slower than a native PPC system, but it can be run by anyone from any desktop thanks to QEMU. You do need to ask for the link to the QEMU image, though. I guess it could be given through a Discord PM.

GDB backtrace when starting the game on big-endian PowerPC

[dwatteau]

Well, I still got the time to do a quick backtrace in GDB, in case this helps figuring out where the issue may lie.

I can't do any more meaningful test at the moment, though.
