No blame or statement about causal relationship, but I do want to mention this here. Yesterday I downloaded the zip, copied the .neo file to my micro sd, loaded Golden Axe up to RAM on my NeoSD Pro MVS, played it for a bit. Works well, looks awesome, had fun. Then, next time I booted up my MVS, all of the sudden all game slots are empty and the micro sd cannot be read anymore. The micro sd can be read by the computer, but not by the NeoSD Pro. Very strange. Today I grabbed a different micro sd, copied my .neo file library to it and it does seem to work. No idea if this quirk has anything to do with the Golden Axe rom, but it's the first time I see this and I hope no one will ever see this happening again.
