Yes, I have recently read that. As a noob, it has taken me forever just to understand where and how to piece together a full set with Mame, so I was trying to get up and running with what I know and have now. Sorry for the noob question but can I use the SL Mame roms I have with these other, better emulators or do I need to get roms specific to these other emulators?

Thanks JoeViking245! Adding the "-cart1" fixed it. I actually had the Atari 2600 roms in both the LB and the original Mame\roms folders (just to troubleshoot) but without the "-cart1", it still would not work. I think I encountered a bug though. When I erase the platform and start over again, selecting Mame as the emulator results in LB finding only 123 games to import. If I select Retroarch as the emulator and point to the same folder, LB find 723 games to import. I wonder why that is. I guess i will have to import using Retroarch and then bulk change everything over to Mame as a workaround. Now I just have to find that "-cart1" trick to creating NES, SNES, Saturn, Apple, and other platforms.

Hi all. I went to Tools > Import > Rom files and added my 4 Apple II folders (at E:\MAME\Roms\apple2_cass, E:\MAME\Roms\apple2_flop_clcracked, E:\MAME\Roms\apple2_flop_misc, and E:\MAME\Roms\apple2_flop_orig). Then I chose Mame as the emulator and "Copy the files into my LaunchBox games folder". However, when I try to play a game, the screen will black out as if it was loading the game but nothing would happen and it would bounce back to the previous game select screen. I have also tried leaving the files where they were (and simply pointing to the roms folder) but that did not work either. Trying to open the game directly in Mame works fine so I know it is not an issue with the Rom itself or a mismatch. (I am on 0.263 BTW). I did the same process when I created an Atari 2600 platform but instead chose Retroarch. Retroarch seems to work, but if I switch the emulator over to Mame, it does nothing. Is there simply something about Mame and software list roms that does not work in LB, or am I just doing something wrong? My arcade roms work fine using the Import > Mame Arcade full set feature. Thanks for your help!
