GT2 Loading Times

My Japanese PS2 is here, which means I can do the Gran Turismo 2 100% now. But, there are some issues.
As you know (or don't, no one follows me haha XD), I did an any% GT2 run a month ago by doing the swap trick on my US PS2. So, taping down the sensors that make the PS2 think the disc tray is still open, changing discs when the PS logo appears to get by the security and thinking it's booting an NTSC-U game. This, for some reason made the game load really fucking fast. That's bad. On the JP console, GT2 loads like normal. Why do I (the reader) need to know this shit, just play.
Ever since I've started Gran Turismo speedrunning I've had this vision of everyone being on the same level, hardware/software-wise. So, loading times pretty much, to encourage people to buy the discs and consoles and stream from that to be fair. Something like a Swap Trick making the game load 30 seconds faster in the first 7 minutes of a run, is bad.
Why does this pertain to hundo? The run is still gonna be fuckin' long and won't sub-26 hours. But that's fine. I still want to do the run.
Gran Turismo 2 100% will be starting sometime Tuesday, when I wake up. This is because there is so much going on this weekend.
Like, Crash Bash 200% race on Sunday, Monday Night RAW on Monday, catching up with the Super-J Cup, UFC 202, etc.
From here on out, Swap Tricking a console for playing foreign games, is prohibited until further notice.
And, I will be deleting my WR from youtube and speedrun.com leaderboard and re-do it on my JP console.
