Hi hi. Thanks for the reply.
I am using: "MAMEUI64 v.221"
I selected to import MAME Arcade full set. However, maybe I messed up. The FULL SET I have is "220 (merged)" (no matter how much I google and READ, I still cant figure out the difference between MERGED SPLIT or otherwise).
Longer story: I had an OLD FOLDER full of MAME CHD files (I dont know what version it is as its old and not labeled, but I read you need CHD for some games?) inside their own folder, IE: C:/roms/mame/azumanga/gdl-0018.chd. SO what I did was, I moved that folder full of folders with CHD inside those folder and strange names to the MAME emulator dirtectory, IE: "Z:\=[Games]=\=[Console]=\MAME\MameUI64_.220 (merged)\ROMs\azumanga\gdl-0018.chd". In this same folder, I have ZIP files, IE: "Z:\=[Games]=\=[Console]=\MAME\MameUI64_.220 (merged)\ROMs\22vp931.zip". So what I did was get that 220 (merged) (not the lates, I think 221 is, but I didnt get that one so I used the 220) and moved all its files inside the ROMS folder overriding whatever it said to override as I assume MERGED means all the OLD version are already in there. SO basically I think I was updating whatever was new?
I am getting Version 221 as I am writing this, SHOULD I move it to the ROMS folder and override anything if its asks me to do so?
