Get the powerpak from retrousb.com. I'm not one to get excited, but I ordered one of these, and it was WELL worth the 130. To add insult to injury, he put them on sale right after I bought mine! Ah well. I uploaded the entire no-intro nes set onto my card (If you're still doing goodnes, it's time to move on) and spent a good chunk of the last 48 hours playing all kinds of stuff. I've been hacking/exploring/digging through nes games for the better part of 12 years now, but once I had my nes controller in my hand, I felt like I was 10 years old again. Actually, when the box arrived I even got that old bit of excitement I used to get as a kid opening a NES box. Little to my knowledge it does famicom disk system shit too! I've been having a blast, and playing unreleased stuff on actual hardware is the ultimate experience. If you have any questions, feel free to ask, I can not sing the praises of this thing enough. I hope there's a snes and megadrive one next!
