GemRB support?

[chilvence]

Glad we solved one problem, I will have to see if I can find another SD card to put base RetroPie and see if I can resolve the scaling issue

If nothing else, the aim is to deal with the resolution automatically, so the next versions of GemRB will not have these kind of difficulties

I will have to let you down gently though, BG1/2 and IWD are much better supported than PST or IWD2 : you can still play the latter, but you will run into unsupported features or gameplay bugs because they are still both heavily in development. Just a hint at the todo list:

https://github.com/gemrb/gemrb/issues?q=is%3Aopen+is%3Aissue+label%3A"game%3A+iwd2"+
https://github.com/gemrb/gemrb/issues?q=is%3Aopen+is%3Aissue+label%3A"game%3A+pst"

You will have much more joy with either game if you use the 'master' branch, but there is still a lot of work to do to make them fully playable

@chilvence To be honest, the BG Games are the only ones that I have played a lot. The other ones I have barely touched. It’s just that I have only the enhanced versions of BG1/2 and they are from Mac App Store, I don’t want to buy them again from GOG just to get the original versions. So I’m just stingy... But someday I will probably buy them again :)

By the way should I bother about the missing directories GemRB complains about when launching a game? Like missing portraits folder or CD X/Data? It launches just fine, but might be a problem later in game maybe?

[chilvence]

@Stuffu Some of the warnings are from the resource manager trying different directories to find the data - if it cannot find what it needs, the game would not load so you can usually ignore them. It's just a result of the modular design of the engine, the resource manager doesn't know exactly what the particular game will load, it just continually spits out a 'debug' output so that we can use it to diagnose problems. The game is actually very loud in the console for this reason.

@chilvence Good to know, again big thanks! This is going to be a good summer :)

[chilvence]

@Stuffu Good luck, don't hesitate to get more support on github or the discord channel if you need it

[Stuffu]

@mitu Thanks for adding latest GemRB in the latest commit, but I don’t see it in experimental packages anymore?

[mitu]

@Stuffu Yes, there's an error that I have to fix in the scriptmodule. Should be ok now if you update your RetroPie-Setup script.

[Stuffu]

@mitu Now it's there but the scaling is the same as before. It's the right version 0.8.6, but wasn't it SDL2 that fixed the scaling issues?

[mitu]

There will be a separate module for the SDL2 version, but what you can do with the current version is enabled dispmanx as the video driver for SDL1 and see if scaling is better.
Go into the RetroPie Setup script, to Configuration / tools, choose dispmanx and then enable it for gemrb. Then start one of the gemrb based ports and see if scaling is still wrong.

[Stuffu]

@mitu Sorry for the never-ending story... dispmanx doesn't launch, below from runcommand:

[PluginLoader]: Loaded plugin "WMP File Imp/opt/retropie/supplementary/runcommand/runcommand.sh: line 1255: 20348 Segmentation fault SDL1_VIDEODRIVER=dispmanx /opt/retropie/ports/gemrb/bin/gemrb -C /opt/retropie/configs/ports/icewind1/GemRB.cfg

[Stuffu]

@mitu Maybe I should wait for the SDL2 version? No rush though. Just happy it’s on the list for future improvements :)

[Stuffu]

@mitu said in GemRB support?:

There will be a separate module for the SDL2 version

Thanks for adding it, tested and it works fine

[mitu]

Glad it works. If you have any suggestions on how we may improve the default configurations, feel free to add them - it looks like right now you're the only (active) user for gemrb :).

[Stuffu]

@mitu Haha, I'm unique! :)

Actually, I think more would have used it if they knew about it. Especially the BG games are really good retro games and still played a lot today. Then again, it's not really an emulator so maybe it flies under the radar for RetroPie. I guess ports are not top in time spent in general on RetroPie anyway...

Big thanks again and I hope it leads to more people finding out about it and some really good RPG's. A must have for all retro fans! :)

@mitu

I hope that it's ok to bring this thread back to life for a newly released stable version that has some issues launching...

A new version (0.8.7, previously 0.8.6 worked fine) was just released. I can't seem to get it to run. No rush, I know that the user base is kind of small :)

I would gladly reach out to the GemRB team on Github if something needs to be clarified, but it seems it's related to SDL2?

[1m[SDL 2 GL Driver]: Creating display
[SDL 2 GL Driver]: Creating Main Surface: w=800 h=600 fmt=SDL_PIXELFORMAT_RGBA8888
[SDL 2 GL Driver/FATAL]: Can't build shader program: 0:1(1): error: syntax error, unexpected NEW_IDENTIFIER

[Core/FATAL]: Cannot initialize shaders.
[Main]: Aborting due to fatal error...


[mitu]

I'll take a look, but it doesn't seem related to SDL2, more likely an OpenGL (ES) initialization error.

[Stuffu]

@chilvence Do you have an idea what changes in 0.8.7 that prevents it from running? If I recall correctly, something was going to be implemented in 0.8.7, like widescreen support or something similar?

[Stuffu]

@mitu I reached out to gemrb and they don’t see anything wrong on their side in the log. OpenGL drivers and shaders are untouched in this release. So likely something in retropie. Still no rush, but wanted to share that to rule out other factors.

[BuZz]

There is an incompatibility with some shader code. I'll have a look.

@Stuffu Can you post a complete log on pastebin.com ?
