I picked this game up as i played the hell out of it when i was younger and it 100% holds up. But Patapon 1 will feel awful for one reason, perfects beats need to be near frame perfect this was the same as the original PSP version. Patapon 2 fixed this issue by extending the amount of frames needed for a perfect note. But these are the exact same games that released on PSP in much higher resolution.

Edit:
Also difficulty of both games alters the timing of notes making the timings needing to be more precise.
