BrianMp16 | Rayman 2 (PS1) - slow down and speed up frame rate by disc tampering @BrianMp16 | Uploaded 15 years ago | Updated 6 hours ago
My friend and I found this horrifying glitch the other day by complete accident.

After my friend bought Rayman 2 for the PS1 to own all 7 ports, (this is the worst port btw) he shortly discovered if you open the disc cover after collecting a green lum, the game will play at 1 frame per second!

After messing around with this for a while, I accidently told my friend to put Rayman 1 back into the playstation. I meant to say Rayman 2. So my friend gives me this look, picks up Rayman 1 and proceeds to replace it with Rayman 2.

From there, Rayman 2 starting playing at an insane speed of 60 fps! After a lot of thinking, I finally figured out why it works. Both discs are made by the same company with the same programming language. But Rayman 1 plays at 60 fps while Rayman 2 plays at 30. So theplaystation reads the coding for Rayman 1 and plays at that frame rate. This is just a theory, it could be right, it could be wrong.

But what really baffled me was when we entered a certain hallway in this level. It played at an even faster frame rate! At least 90 fps. But it only happened in this hallway. The only thing I can think of is there is only 1 sprite which can be killed in this hallway, so the game can play at its maximum speed that way.

My friend and I have just recently discovered this glitch and haven't messed around with it in many other levels. We know it works in some and doesn't work in others. So if anyone finds any additional side effects of this glitch, let me know and I'll credit you.

And in case you're wondering, yes, you can complete an entire level in this speed. Just make sure to leave the disc out for a while and put Rayman 2 back in before entering a loading sreen.

And yes, this works on the level selection screen too, you just have to get a green lum in some level beforehand.

Enjoy!
