Hi, I prefer not to touch the laser on my ps2, and I want to know if it is allowed to run the game on an HDD or USB, it's a valid run?

No because the loads sadly get drastically affected, also rac 1 is better to play on ps3

I'm trying to buying a ps3, and i know about the time load in PS2. My question was is it is a valid run

PS2 runs can only be done with a disc if you want to submit to the leaderboard

PS2 on this game is slowest, but you can try to have the world record PS2

actually you can do PS2HDD Runs on OPL but its time gated to 20min + Rac1 on ps2 is slower than on ps3 anyways
