Rayman 2: Revolution oddities on PlayStation 3

[Spectremint]

I recently played through Rayman 2 for the first time, using Revolution as it's the most accessible version to me at the moment for playing on my TV. I did in fact beat it! However, throughout, I noticed a small handful of oddities that I'm currently unsure if are caused by simply being the PlayStation 2 version or if it's because I played the game through the PS2 Classics version on PlayStation 3. All of these happened to me after having played the game for a while without resetting:

• In the Prison Ship, the wall hitbox during the flying shell segment unloaded, which made me fly through walls

• In the last mask fight, the puffy clouds didn't join together at the top, causing the fight to become unwinnable until the system was reset

• During one especially long play session, the sound for the chase on the bridge near the left side of a mountain (I have completely forgotten the name but I wanna say it's the Precepice?) broke completely, causing it to go mostly mute

Any idea on how or why this happened, and/or if it's an issue with just the PS2 Classics version?

Oh, and for those curious on my stats:
TIME PLAYED 51506 S
DISTANCE COVERED 370361M
NUMBER OF JUMPS 4698
SHOOTING ACCURACY 49%
TIMES KILLED - 235
NUMBER OF TRY AGAIN - 60
... needless to say, I think I struggled xD

Hi there! I've never played the PS2 Classics version (I don't think it's available in Europe anyway?), so it certainly didn't happen to me, and it's the first time I'm hearing about this, but it's probably just a bug nobody's come across so far.

Maybe they updated the game or emulation issues or something?

Something happened when my brother played it. He got this glitch where the helicopter hair could be heard even after it's not supposed to be heard, and other times you use it, it would be heard and multiple sound clips of that are playing at the same time. That isn't necessarily a PS3 exclusive thing but it was on there he got that.
