So I've had my PSP hacked for years, but haven't been involved with it much for the past few. I just hacked my friend's Phat PSP for him using the Scorpus's chickHEN tutorial and am now running 5.50 GEN-D3. Having been out of the game for so long, I'm not sure what the latest and greatest CFWs are. His intention with it is to play old NES/SNES games (I showed him Super Smash Bros 64 and he just about lost it). My question is just what would be the best CFW to give him?
