Everett1954 Posted January 18 Share Posted January 18 (edited) Hi, I am using the latest version of LaunchBox on my Ayn Odin Pro hand-held with all latest updates. I cannot seem to get any MAME .139 roms to play. I have tried both RetroArch and Retroarch64 with the MAME2010 core and all i get is the black screen. I tried MAME4DROID and while the games all show up fine (also in LaunchBox) I am not able to start any of them with onscreen or odin controls. Amy help is greatly appreciated.

While my name is not Amy I'll try to provide any help I can. 😉 There's potentially a number of issues you may be facing. Here's what you can try: I'm guessing the issue started during import. If you can, long press over the Arcade platform and delete it from LaunchBox, making sure not to delete your ROMs and Media when those prompts appear. Then re-run the import, but during the second import page de-select the option: "This is a Full MAME Set". Then run the import. This should help you better import your old set. Then, I'd make sure that you have downloaded the core you want to use inside of RetroArch, and then select that core under LaunchBox's Emulator Settings for the Arcade platform, and see if you have any better luck there. You'll also want to make sure that the emulator setting to extract ROMs is turned off. Quote Link to comment Share on other sites More sharing options...

You'll then get another prompt asking if you also want to delete ROMs, and then a third prompt asking if you want to delete media. Quote Link to comment Share on other sites More sharing options...
Everett1954 Posted January 19 Author Share Posted January 19 Hi, Thank you very much for your help. So my problem was the initial Import with a full rom set checked when i really didn't have that. After resetting Arcades, i noticed that i had a lot of games that just did not work. I completely wiped roms and Megadata and am now using a a smaller collection of MAME 0.78 (MAME 2003) with 32bit Retroarch and Mame2003 core and everything works in LaunchBox! those external MAME4Droids are no longer needed and deleted. 1 Quote Link to comment Share on other sites More sharing options...
