(That's an EZ Flash V on it with fobby's translation).
Still one of my favourite designs, even though lately I find it fairly straining to my eyes.
Check this out. You'll probably need to source a replacement latch to fix it though.
So I bought a copy of FFVI Advance and dug my Micro out. Popped the faceplate off to give it a clean and now it won't clip to the micro when I try to put it back. Seems like the faceplate itself is fine, the hooks like perfect. If whatever those hooks clip onto in the micro itself have broke, am I screwed? This happened to anyone else?
