Long-time gamer, new collecting--
I've been looking at NES games on eBay and seeing some boxes with "Rev-A" printed on the cover. All I could find from searching the Web was that this designates a UK version of the cart, but one seller I contacted said the game plays fine in a US console. Is there any difference between US and UK versions? I thought that the UK used PAL and wasn't compatible with NTSC, or does the "Rev-A" actually designate the US version? Any help clearing this up would be much appreciated.
