Hi Jason, long time user, recent poster.
I REALLY like the way Launchbox is going, specially since you took it as a full time commitment. Mad props! I must confess I use beta but no not always read the beta notes on the forujm, and this might be a known issue.
I tried to add some Capcom-CPS1, 2 and 3 since they were added as categories and work just fin with Retroarch (I am trying to move toward retroarch more an more). The point is about the scrapping! They scrape just fine as category arcade, but nothing but the vids come up as image etc... nless I put them as category arcade. I tried to differienate them by adding an extra field, say source, but retroarch still tries to launch them with MAME core, and not FInalBurn. In a related note, the SEGA 32X category comes up as empty as well.
As I said, this might be a know issue, I just hope it gets sorted soon-ish!
BTW, mad props too for the new MAME import Filters! They rock! Thanks Jason, keep up the good work!
