I'm also hoping for a region free hack to be discovered. That's all I care about really. I'll gladly buy both Project Mirai's legally. I do admit to having the Project Mirai 1 ROM in my possession (from where I won't say and actually I don't remember where I got it from), but that was when I was ordering my flashcart and when I didn't realize that the one I got only play DS mode stuff (homebrew / DS ROMs etc) and I thought I could play PM1 using it. I also overlooked the fact that even with the proper flashcart you need OFW 4.1-4.5 to run anything. >_>...
Anyway, I love Project Diva (PSP and Vita) and I was really looking forward to playing Mirai 1 and 2, oh well. I've preordered Project Diva ƒ 2nd, and I'm super stoked for it. It should be fun.
