OK, so I've done some additional trial and error testing. I'm pretty confident now that the problem is that retroarch does not know which bios to grab when launching apple2 games. Can you think of anything I could add to the "Extra command-line parameters" in Launchbox that would tell retroach which bios file to use?

No, I had changed it, but I reconfigured it so the path is now correct. SUCCESS: I can now launch apple 2 games with Mame standalone. Now I just have to find out how to get the retroarch mame core to do the same. clearly there must be some rom file(s) missing in ma apple2 folder...

Well, my Mame just gives me this message without telling me which files are mising:

Thanks for the info. I am a total noob however and don't know how to launch anything from a command prompt. Where and how do I enter this command prompt? Will I have to change anythin if I use software lists?

So if I use mess2015 core, retroarch launches and I get this result: Is that progress? =D

I've just tried MAME standalone, but it doesn't work as well. I may have set it upincorrectly though. I've never really used mame standalone. Besides, all the other 5 systems seem to work with my method. I have the strange feeling that it might have to do with the different bios versions and mame not knowing which one to load...

I've just tried this, but unfortunately, retroarch still crashes when I try to launch a game =(. Do you have any other ideas?

Thx for the suggestion. Will tray that once I get home. I've also realized that there are many different apple 2 bios files, such as apple2ee or apple2ep, and so on. Which of these should I use? And if I decide to use a bios other than "apple2.zip", does that mean I have to change the name of my generation folder to "apple2ee" and rename the hash file to "apple2ee.xml"? Also I have found that there are more XML files for apple 2, such as apple2_cass.xml. how do they factor in here?

Hey everyone, I've recently started adding a bunch of smaller systems to my Launchbox collection, but since there aren't any specified cores for them, I haven't gotten them to work, until now. Using Retroarch's Mame core, I was able to launch the following systems: - Philips CDI - Emerson Arcadia 2001 - Entex Adventure Vision - Fairchild Channel F - GCE Vectrex However, I just cannot for the life of me, get Apple II to work. If I try to launch it, retroarch will crash. So here's how I got the other systems working: The process is rather simple if you know how to do it (example Fairchild Channel F). 1. You need the system specific hash file in place at: YOUR_PATH\RetroArch\system\mame\hash\channelf.xml 2. You need your games in softlist format named and zipped in a way that is readable by mame (e.g. alieninv.zip) 3. Your games must be in a folder named after the softlist entry in the hash file: YOUR_PATH\channelf\alieninv.zip 4. The BIOS file(s) need to be in the samefolder as the games: YOUR_PATH\channelf\channelf.zip 5. In Launcbox --> manage emulators --> associated platforms, change the core for Fairchild Channel F to mame (without name tags) This way I've been able to get these 5 systems working. Apple II however alsways crashes retroarch, even though I've folllowed these exact steps: 1. You need the system specific hash file in place at: YOUR_PATH\RetroArch\system\mame\hash\apple2.xml 2. You need your games in softlist format named and zipped in a way that is readable by mame (e.g. alf.zip) 3. Your games must be in a folder named after the softlist entry in the hash file: YOUR_PATH\apple2\alf.zip 4. The BIOS file(s) need to be in the samefolder as the games: YOUR_PATH\apple2\apple2.zip 5. In Launcbox --> manage emulators --> associated platforms, change the core for Apple II to mame (without name tags) So I'm stuck here. Does anyone know where I went wrong?

I figured it out. The black bars appear if I set the graphics scaler to something other than "normal". Graphics filters work well for some games, but not for all of them.

Thanks for the reply, exo. I use a desktop PC with an nvidia card. Other than nvidia control center, I don't use any GPU software. I don-t know about hardware acceleration. How do I turn that on/off? Could custom DPI settings play a role? EDIT: It's not the DPI settings, I just tested that. Additional info: I do use multiple displays. One of the displays runs in 1080p, the other one has a higher resolution. I'm not sure that this is the problem, though, since every system I emulate (other than dosbox) works with this setup, and there are some dos games that display correctly, as I mentioned. I've since found more games that display correctly:

This is wht most of the games I launch look like. How can I correct that? This is the only game being displayed correctly so far:

Thank you so much for all of your hard work eXo. This pack is the easiest way to get Dos games up and running! I would like to know if it is possible to run your collection through retroarch, since I would very much like to use overlays. If this isn't possible, I would like to know if there is any way to change the resolution the games run in. Some games just run in a rather small window within a large black frame (when I run in full screen). Correcting the aspect ratio in the config menu does nothing.

Hey there, I've just tried importing an MS-DOS collection into LaunchBox and I have noticed that many games have the wrong names. For example, LaunchBox falsly identified the game "Lords of Doom" as "Doom". I think this happens, because the .exe of "Lords of Doom" is called "Doom.exe". Is there a way to make LaunchBox use the folder names for DOS import? I think that would solve this problem. Thanks!

Thank you for this tipp, however, I really don't want to rename all of my roms, since I've already importet them into Launchbox and I have save files within retroarch which match the exact rom names. I think it would be great if a tool scanned for something like file size to identify roms, but I guess something like this doesn't exist.
