I've come across alot of snes beta's. obviously unreleased games for the most part are worth playing. Im not really into rom hacks unless they are totally new games not just re-skinned old games. so what is the real difference between for example: Aladdin(beta) and Aladdin (E)[!] so my real question is are beta's worth having along side original dump? Also out of interest is there a European version or USA version difference for emulation, does the 50/60 Hz matter if playing trough emulation ?
