I'm not sure what exact emulator 2w used in his run, but whatever it was, the loading time for the first level was 9 seconds faster than on PS2 SDS. (2w had the cutscene start at 37s, I had it start on 46s). If this time difference is the same for every level, then he would've gained more than 2 minutes on my time on just the intro loading screen alone (the outro loading screen might also be faster on emulator). As this isn't really a serious/competitive game right now, I'm not too bothered about faster-emulated runs being on the leaderboards, but I thought I'd give note about it for future reference and to open up a discussion about it.
So this is to all PS1 emulator runners for this game, as I have been watching footage back from runs many years ago set by myself and Shoegaze (The other runner competing for WR alongside myself) I have spotted that the game is running at near enough full fps without any or very little slowdown.
