[quote name='whitereflection']Does this actually hold up well? I played Um Jammer Lammy when it was free on PlayStation Plus and couldn't get past the first stage. (I beat it when it was released on PS1 way back.) I tried it on both my PS3 and Vita so I don't think there's any audio lag issues that would cause me to fail.[/QUOTE]
I thought Um Jammer Lammy still held up great on my psp/ps3 and had no problems. Go figure.
The psp Parappa seemed that way to me, though...like the timing was slightly off, and I kept missing things I thought I nailed...or getting penalized for cool improvs (although I guess the improv system was probably more bare bones on that game than the sequels). Took me a bit to adjust to the timing of the game for some reason. Once I did, it was still fun, though.
