Are there any plans to separate the MAME rom folder from one into two. One for the Libretro and one for the ADVANCEMAME and update the UI to have two sets of MAME.
Just find a bit of a nuisance to dump all my mame roms into one folder and then go into the Advanced settings-->Advanced Emulator Configuration-->mame and flip it from one emulator to another based upon which of the two the game runs on.
