romruler Posted April 15, 2017 Share Posted April 15, 2017 I am not sure what I am doing wrong, but I follow the tutorial to a T and I cannot launch the games from LB or from RA. I have tried this: - I am using the latest stable version of RA. - I have tried bios from multiple versions. All named (renamed) to O2ROM.BIN All put in the system folder of RA. - I have tried using the nightly build of RA thinking it may be different. - I have tried roms in .zip format from multiple sources thinking I may have had a bad dump. - I have tried RA which I have emulating many systems, I have tried a fresh download of RA with only OEM2 as the core. If I try launching OEM2 from RA, once I get to launching, it says that they wasn't any content. It is the same message as when I tried to launch it without O2ROM.BIN bios in the system folder. I would have to think it is the bios, but I have tried 3 different source bios all renamed to O2ROM.BIN I am at a loss of what to do. The only thing I have not tried is using OEM2 as a standalone. Any help would be appreciated. Cheers. Quote Link to comment Share on other sites More sharing options...
spycat Posted April 15, 2017 Share Posted April 15, 2017 I can't speak for Odyssey 2 emulation via RA as I don't use RA. However, the dedicated emulator o2em works fine with LaunchBox. MAME can also emulate the Odyssey 2. To emulate the Odyssey 2 in MAME you will need the machine's romset odyssey2.zip And your Associated Platforms Parameters for the platform will be odyssey2 -cart1 If you also want to emulate voice synthesis for the games that use this feature you will need the voice passthrough cart o2_voice And your Associated Platforms Parameters will now be odyssey2 -cart1 voice -cart2 By the way, since MAME emulates the speech synthesis chips, the wav samples that the o2em emulator uses are not needed here.

wemr97dl Posted April 16, 2017 Share Posted April 16, 2017 Just Set this up myself and the same thing with the oem2 from RA, Switched to MAME and everything seems to be working, Maybe a bad module?? Quote Link to comment Share on other sites More sharing options...
romruler Posted April 16, 2017 Author Share Posted April 16, 2017 Well I figured out the issue. O2 did not open for me in RA 1.5.0, but if you use RA 1.4.1, it launches right up. So it is something in RA 1.5.0. Thank you to all who responded. Quote Link to comment Share on other sites More sharing options...
