Hi guys, planning to run the psx digital version, but need to clear my doubts

1. i realized the rules has changed, i rmb previously it was written emulator psxfin is recommended, but it has changed to retroarch 1.9+ now, is this mandatory?
2. tried out retroach 1.9.8, this version acceptable ?
3. under rules also, stated Load Settings: "CD-Rom Seek Speedup: Infinite/Instantaneous" and "CD-ROM Read Speedup: 2x (Quadspeed)" << any guide on how to configure this? i couldnt find this option
4. psxfin still allowed?

Thanks guys.

Hi guys, i plan to do a full run of this category, currently practicing a segmented speedrun. However i have some question to clarify, some being quite serious that i think will disqualify my run, others i think i know the answer but just need confirmation:

1. I know u need to show video FPS capped at 30fps, so i followed the guide and installed DXtory and FPSfix, tuned the setting in .txt file. So the question here is, i realized during some screen it still goes above 30fps i.e 30.01, 30.02, or 30.03, does this count as disqualify if it happens ? (most of the time its below 30.00fps)

2. I had PTown told me that my chocobo race in desert prison is faster than usual, i checked some completed run in this category and mine indeed is faster by quite significant, i think this is a glitch, how to fix this?

3. Whirlwind area, the screen before jeno death fight, the fog is okay but the "wind" that crosses from right to left, i see its moving extremely fast and disappear from time to time, i think it is similar kind of glitch with above, how to fix this?

4. i know can save and if die (game over) then just reload that save point, however if say i failed CC skip and i want to reset, i just go to menu and quit, then launch ff7 again ? ( i know need to run the fpsfix before launching it)
