Personally, my PSP does use emulators that require hacking. But hacking is incredibly easy now and the best part is that the N64 emulator I use does indeed have a signed version, meaning you can play it with a non-hacked PSP. Here's a link to their download page: http://forums.daedalusx64.com/viewtopic.php?f=12&t=3688 Just download the signed version, put it on your "GAME" folder, and that's all there is to it.
Hi. I hope you dont think it's inappropriate of me to ask if you had to hack/mod your PSP to get SSB64 on it. I know that some emulators work without the need of hacking & I'd love to put some N64 games on my own PSP
