Accurate emulators do not have fast disk speed. This includes mednafen/xebra/bizhawk/beetle/etc.

Duckstation, notably, DOES have a working adjustable fast disk speed option. It's been stated that with the the fast disc speed option on, that a ps2 cdrom loads ps1 games at 12x. So upping speed to 6 (12x) should replicate the time saved by fast disc speed if it works on a ps2 that way. Note that some games can't handle that, but any other setting for fast disc speed will not match any hardware.

So it's worth doing tests in duckstation at 6 (12x), which should be as fast as a ps2 in good condition. going above that will definitely be too fast.

tcrf to the rescue.

1.0 has no wingsmash chaining, has a glitch that lets richter fight dracula (but the game freezes after), and doesn't have wargs dropping their karma coins.

1.1 has the drop bug fixed, enables wingsmash ciaining, and has an exclusive glitch that allows corruption by rapidly swapping items. It also corrects some bad data in two of the enemies.

1.2 adds the lyric feature, undoes the aforemantioned fix to the tombstone and archer (because the international versions have it unfixed there), fixes the swap corruption glitch, and allowes the double fire boomerang trickery that will crash the game in earlier JP versions (but works in US) to work properly. Oh, and richters flame whip is changed to fire elemental.

The combination of save corruption and fire boomerang issues does mean 1.1 is different, though this probably doesn't matter unless you manage the game end glitch

If you press the triangle button on controller 2, the bridge instantly breaks.

X360 version is an overclocked emulation and it's already on the leaderboard.

Specifically if you do a 200% cpu overclock, and speed up the cdrom to 4x it's original speed (so 8x), you get the same performance as it.

Having x360 version on the same leaderboard as console really isn't fair, because of the built-in overclocks.

Going over 200% overclock indeed breaks things at a certain point, but a 200% overclock and the cdrom speedup i mention gives parity with the x360 version.

Photn with touchscreen is weird.

Photn with controller is same as ps4 pal version, except even faster load times and 'continue" option.

it CANNOT be put on same track as psx version, and might even be unfair to put on DXC track.

Mobile is essentially DXC Requiem PAL, with an added Continue option that restarts you form the room entrance, UNLESS it's a boss oom. ten it rstarts you form the previous room entrance.

The continue option is what makes times not comparable.

Oh, and the instant loading. so it's the fastest version of them al.

so yeah, it would need to be tracked separately.
