kpdavatar's All-In-One Converter ... Thing
This thing is awesome. It slices, it dices, I've heard it'll even do your homework for you. It will convert from AR2 to Hex to CB2 (8, 16, and 32-bit Writes). You can even store codes in it's "memory", just like a calculator. I have a feeling this will eventually become the ultimate tool for PS2 hackers. Click the Info button for ... umm ... more info, of course. Huge thanks go to kpdavatar for this gem.
