Its permited for the console runs?

I have the original disc but my PS2 doesn't work because of the optical reader.

So here's what I've found. OPL would likely have to be it's own category due to faster loads than Emu and real disc. In my experience it takes my hard drive (Sata modded official network adapter with an HDD) about 10.5-ish seconds to load Maui. On emulator (all versions/regions), in fosteredpancakes' run and hypnoshark's run on real disc it takes the game 13-ish seconds consistently to load Maui.

As far as I can tell, OPL just loads faster than every other version of the game.

I see that it wouldn’t make sense then because i use a pendrive in my ps2 slim but if in the future the category is added... I will try it! Thanks for answer <3

If you've got a flash drive loading games off USB in the front ports you'll probably end up loading slower than a person playing off a hard drive or a disc. OPL is bound to have a lot of goofy things with loading due to where it's being loaded from.
