I have MAME merged no chd, the popular consoles, PS1 USA, GameCube, NeoGeo, Saturn, Dreamcast, Commodore 64 etc. Only the basic systems everyone has. No Wii or PS2 yet (I'd need another HDD). HyperSpin, LB (currently missing most of the art), and all the art HyperSync downloads. My 3tb is nearly full.
Sorry if I came off negative. LB/BB is great. I'm just stuck since I switched systems and had to reformat my hard drive. I copied LB over to a flash drive but the artwork wouldn't fit. On the new system, I let LB download metadata overnight and it was only 1/4 finished the next afternoon. Most of the art is in my HS folder already, but I can't use it the way LB is setup (and HS). I have to duplicate everything or else go game by game pointing all the paths. So for the time being, I'm back to HS.
