OK, thank you

@ectoone Yep, i figured i'd have to adjust the paths. I'll give your suggestion a whirl, thanks!

@dafioram Lol, I only just now realised you're the same guy from the ScummVM forums where I mentioned the vkbd speed bug. /wave

@mviars Yeah, I am using SCUMMVM and getting back in to Riven after transferring my 5 CDs that dug out of an old box. It works great. Fullscreen is working fine but it does leave black borders on the left and right sides which I expected. I am using defaults for video and render, but messing with some of the scale settings yields interesting results for games like DOTT and Full Throttle. Some settings slow down the interface. I am basically using default and OpenGL. This works great with my 8bitDo bluetooth controllers too. Analog stick moves the cursor. Myst/Riven is pretty fun on the big screen and comfy chair!

@dudleydes Better than nothing. At least we have a means to make the changes. I guess I won't be updating too often though ... :P

Or you can just rename +Start ScummVM.sh in your scummvm rom folder to +Start ScummVM.s. Wth that you don't need a gamelist.xml and still can easily restore it if you need it. Although I'm sure, whenever you update ScummVM it will be restored. Or if you sure you never need it again, you can just delete it.

I like ScummVM simply because its easier to use than DosBox. Plus, I can run the games on my Android Tablet as it's compatible with the touchscreen.

@mitu thanks, I'll look for that option after the scraper has finished (found that while looking for the install options and once I realised what it does I just had to do it). not all have the same files it seems... Driver has a .bin.ecm file, GTA2 and Dark Forces have a .bin and .cue file, Rayman has a .bin.ecm file and dozens of .ape files, Spider-Man has a .ccd, .sub and .img file... Those are the only ROMs I downloaded because they're the only games which I actually bought (for my brother's PS1) but I don't see a real overarching approach here. I don't have a bios file... I saw the Dreamcast page saying something about that but I didn't even have its map so I didn't think anything of it. I see both the Dreamcast doc and the PS1 doc talking of a BIOS file but I didn't get that the emulators are actually missing files; I don't know ehat BIOS files are and do, or where I should get them (probably worth a Google, I'll do that today).

@arcadetv Hello! Appreciate you looking into all this - I'm trying to get scanlines working on scummVM (retropie) and I've dropped your script into the folder you stated. Could you tell me how I activate this though, as when I go into my options in ScummVM I still don't see these scanline shader options right now. Cheers! James

I found a workaround: I added a .scm-File to the root aof the scummvm-games-folder. For atlantis i have the atlantis.scummvm-file insidde the atlantis-folder and a atlantis.scm-file outside that folder. In es_systems.cfg i changed the command: <command>RetroArch\retroarch.exe -f -L "RetroArch\cores\scummvm_libretro.dll" "PATHTORETROGAMES\retro\ScummVM\games%BASENAME%%BASENAME%.scummvm"</command> and changed the extension to scm. <extension>.scm</extension> This means EmulationStation sees the .scm-file as the rom and adds it to the gamelist without annoying subfolders. When starting the rom, wo don't care about the fake .scm-file. We grab only the basename and assume there is a folder with the same basename with the scummvm-file inside it.

Brilliant, Thanks for letting me know so quickly. I will install and configure these emulators outside of Retropie using sudo apt-get install. I will keep tracking this in case they may be ported to the XU4 in the future. Thanks all!

@dudleydes - Thanks for the steps. I tried it with the -sdl1 and used a XBOX 360 joystick. It took about an hour and 15 minutes. I ported it over to a new build. I just needed to temporarily change permissions on the directory/file and chmod +x scummvm to make it an executable and it worked perfectly on the handful of games I tested. The default controller layout of scummvm is definitely less than optimal so this is a nice tweak.

@darknior Wow bud.... You're all over the map, aren't you? Careful that you don't spread yourself too thin with too many projects at once. I did that myself back in the day and it literally drove me insane. :)

@sammyboy you shouldnt use runcommand for dosbox. Dosbox has its own video settings in the dosbox config file. Also follow the retropie dosbox wiki to learn how to create seperate .sh files for each game.

After loading ScummVM through command line, I get this error. WARNING: SDL_SetVideoMode says we can't switch to that mode (Could not initialize OpenGl / GLES library)!

Thanks for the reply. Hmm, yeah, probably should have read the rules. Ok, interesting. The comicbook themed pre-built image that some guy I met down the pub was showing me didnt have either of those systems, but maybe his just didnt have any roms, or he'd removed them. Not that I'd play any of the roms if he did. I'll look again...
