I just started up my PS2 and played some Beatmania US (only IIDX I could find, since the others were burned copies). Somehow, I can still play rather well, and might actually be better than I was before, if I practice for a while. Some songs that I could almost pass before completely destroyed me, but I could do pretty damn good, all things considered. My timing is crap, but it's always been crap on IIDX anyway.
