Thank you for your help.
1. Yes, I can see the ROM, when I press X to load, screen goes black, and returns me to what it seems a retroarch screen, if I press X again in retroarch, it says error loading ROM. I get the same error when using other versions of FBA.
2. No I havent, ROM'S are all taken from my FBAnext from my xbox 360, and they all work perfectly there. Could this be the problem?
3. I was trying to load Metal Slug 1-5, none worked, pretty sure its neo geo.
4. Yes, they are all in zip format.
Also, this is weird, but after installing this version of FBA, I cant seem to find the folder to which it is installed. I have placed ROM's in /dev_hdd0/ROMS/FBA.
These directories are not there, I cant see them.
What I can see is this /dev_hdd0/game/FBAL00123/USRDIR/cores/roms
Thank you again.
