I have a portable Famicom clone system. I like it but most of the games on it are crappy unofficial games. Most of the games I would like to play are not on it. I've looked up Hakchi, which can flash the kernel of the NES Mini. I tried using it on the FC Pocket but it doesn't work. Is there any way to change the roms on this thing? I'm a novice at this stuff, so I'd appreciate any feedback.
