My AmigaOs4.1 projects

@Maijestro

Thanks for your work!

Do you know if Roland MT-32 is supported in your port? I can't get it to work (I could make it work witout any problem with older versions).

Same question for soundfonts regarding MiDi audio output.

Hi Everyone!

First, I think testing ScummVm is a lot of fun! I love this emulator, one of my favorites.

Okay let's get started with the new version. I have an AmigaOne 500 with Radeon Rx 550 completely updated and I have the latest versions of all the libraries that ScummVm requires per the included readme. Also, the Vulkan 3d graphics works on my AmigaOne.

First the good news, the load time is much better. It is really quick now. Also, all the Sierra games are running perfectly in this version as well.

Second, the bad. Okay, in global settings on the GUI tab, if you choose anything other than 100% - Medium for GUI scale and apply it, then go back into the global settings and choose a working shader for example or Fullscreen mode, I get a requester stating "Surface: transBlitFrom: bytesPerPixel must be 1, 2, 4! and then when you hit okay ScummVm quits.

Third, I tried to test Ultima 8 since that engine has been ported over and when I hit start I get "Error running game: Could not find suitable engine plugin".

Fourth, the Vulkan graphics does not work at all for me. When I choose it and hit apply, I get a requester "Assertion of condition dest x>=0 && dest X < w" failed in file graphics/Surface.cpp", line 259." I love the "Sorry" Button in the requester, a nice touch lol.

A request, the Might and Magic Plugin would be great! I want to play that series after I finish Ultima 8.

If you need anything from me, more details on the errors I am getting, just let me know Maijestro.

I don't think the Roland MT-32 is fully implemented yet. I promise to add it in the next release.

“I get a request stating ‘Surface: transBlitFrom: bytesPerPixel must be 1, 2, 4!’”

Thanks for the information; I haven’t quite figured out what the problem is yet, but I’ll look into it.

“Third, I tried to test Ultima 8 since that engine has been ported over, and when I hit start, I get ‘Error running game: Could not find suitable engine plugin’.”

Ultima 8 probably requires an additional engine. I will, of course, add the Pentagram engine, and the same goes for Might and Magic, which requires the Xeen or MM engine.

As for the Vulkan graphics manager, I’ve only just started working on it and I’m not sure if I’ll be able to make it work properly and use it for ScummVM. Right now, it’s more like an alpha or beta and doesn’t work. The background of the ScummVM theme is already being rendered, but that’s about it.

@Maijestro

The full screen mode in the global setting knocks my monitor out of sync and I lose the picture.

Might be something to do with my set up.
Also couldn't get the Vulkan option to work.

Without those options, seems to be working well so far.

The Ultima engine didn't work with the versions I have for 6 or 7 sadly.
Couldn't get 7 to work with Exult either so it might just be the versions I have that are the problem.

Cheers

@Orgin
thanks and sorry.

ScummVM should have a 4-megabyte stack cookie unless it was removed in your build. It sounds a bit overkill, don't know if anyone tried to measure the actual stack usage.

I also think 4 MB is a bit excessive, but I could increase it to 1 MB. Currently, ScummVM uses a stack size of 32768, and it’s stable, but for some engines, a larger stack size might be beneficial. Thanks for the suggestion.

Would switching from SDL2 to SDL3 make sense for ScummVM? In other words, do we currently see any benefits from using SDL3?

@all

Please use http://crashlog.os4depot.net/?functio ... ile=game/misc/scummvm.lha and post your crash logs or information about ScummVM there, and I’ll take a look at everything.

Tried this version, Grim Fandango does not work well at all. Crashes SCUMMVM, all dialogue sections missing.

Glad to find 2.9.0 still available at https://www.scummvm.org/downloads/
Disappointing to see that it was over written at OS4Depot.

@Maijestro

I meant the stack cookie in binary itself. Smaller icon values have no impact.

SDL question is tricky considering also different C library variants for AmigaOS 4. Use what works for you. My pick is SDL3, it's cleaner and it gets new features. SDL2 is more or less in maintenance mode.

@yogi32

Hmmmmm ScummVM 2026 2.0 and Ultima 8 are working on my MorphOS system .. the Engine should be supported afaik.
Some footage..

@Skateman

Haven't got Ultima8 but just tried Ultima6 on ScummVM version 2.9.
Worked on that version but not the latest.

Cheers

@Skateman

You know, AmigaOS 4.1 lags behind almost everything MorphOS already has. Congratulations—then the new engines and games shouldn't be a problem

Necronomicon: The Dawning of Darkness
Crime Patrol
Crime Patrol 2: Drug Wars
The Last Bounty Hunter
Mad Dog McCree
Mad Dog II: The Lost Gold
Space Pirates
Who Shot Johnny Rock

Since Ultimate 8 is in high demand, I’m going to try to get this engine running next. I’ve since bought the game because no one is properly testing it or providing information about it. What no one seems to realize is that new versions sometimes bring a lot of changes, all of which need to be taken into account so that I can continue using the new version without any issues.

Right now, I don’t want to rush out new ports; it’s more important to me that everything works properly. I’m still dealing with some engines that aren’t fully functional, including Grim Fandango and other games like Syberia 1 & 2. I’ll think about it once those issues are resolved. But yes, I know Syberia 1 and 2 also run on MorphOS, just like the Wintermute Games

@Maijestro

Am I right in thinking that newer versions of ScummVM need the engines recreating?

Cheers
