PS1 vs PSP comparisons

[Mateoski]

Everyone knows that Mega Man Legends 2 got a rerelease on the PlayStation Portable, but only in Japan. I'm sure everyone remembers Nino Ruins and how much of a pain it was to traverse through it as well as the Kimotoma Ruins (Class S license ruins in Saul Kada Island). They actually fixed this issue in the PSP version of Mega Man Legends 2.

I've made two videos showing comparisons of both versions to show the differences between the two. And sorry about the blue lines in the PSP version. That's just a glitch caused by the PSP emulator. This doesn't happen on an actual PSP itself.

For the Nino Islands video, the PS1 version starts at 0:20 and the PSP version starts at 16:13

For the Kimotoma Caverns video, the PS1 version starts at 0:23 and the PSP version starts at 13:54

At first I thought the slowdown was on purpose, later on I blamed hardware limitations but then I realized that running on an emulator on a pc would fix the issue but it doesn't. So was it caused by bad resources management or something?

If you try to play it on emulator, especially with shaders or hardware GPU plugins, the framerate takes a nose dive on Nino Ruins and Saul Kada Ruins. There's probably something with the wavy-screen effect that affects the graphics processing.
