I apologise if this has come up before, but I am having a hell of time getting NeoGeo roms and CPS1, CPS2, and CPS3 Roms running.  I am using Retroarch and have followed the tutorial videos.
 
	As far as I can tell I am updating my cores (FBA_Libretro) and I have placed the neogeo.zip (bios) in my roms folder.  When I attempt to run a rom, it either flat out does not do anything or by running a few of the different cores the roms start to boot and seem to hang at around 90%. 
 
	If anyone has a fix for this, or any helpful tips I would be incredibly grateful.  So far my experience with launchbox has been great, if I can just crack this nut it will be nigh on perfect.  Thanks in advance
