Just came here to post about this.
I have RA and the cores setup and working right (Mame2003_plus) perfectly with Daijisho launcher on my Odin Pro. However, with LB, it finds and scraps the games correctly (from what I can tell) but when running a game, I just get a black screen and nothing else. I've tried different cores, and even different emulators just in case it's that, but I can't get any of them to work. My ROM set is the 2003+ set and works everywhere else, on my PC and other handhelds (MiyooMini+, RGB30), all through RA and even, as I mentioned on my Odin Pro with Daijisho but not with LB for some reason. All other systems works perfectly, it's just MAME that's having the issue. All cores are installed and work manually through RA too, the issue with when launching them through LB.
Is there a particular ROM set that works with RA Android or should any? Would anyone recommend a different set anyway?
Thanks in advance.
