I don't see any way for launchbox to handle a single game for both playing games that supports hiscores and retroachievements as the following issue is
retroachievements = requires Retroarch cores that don't support hiscore
Hiscore = Requires Mame64 that don't support achievements
and the way launchbox is designed is that it looks at the default emulator and shows the information in the "game detail" box. so you cannot assign both mame64 and FBneo for a game and show both details.
have anyone found a workaround for this issue?
and for mame sets, how can i assign specific emulators for combined games. do i need to expand it first and assign, and then combine again?
