There are two extremely rare Korean editions of this game that were released. And one of them seems like it could be slightly faster for 106% IGT.

One of them, Korean 1.0, is almost exactly the same as NTSC-U 1.1 except for a couple tiny changes. The other, Korean 1.1, is fully dubbed with Korean voice actors and Korean text. Otherwise the same as NTSC-U 1.1.

Korean 1.0 has a glitch where once a time trial is completed, the game automatically enters three characters into the name entering screen and also automatically goes to the next part, which is finishing the level (or onto the screen where you can select restart trial or warp room if no relic is achieved). This is more consistent than manually pressing done at the bottom in other versions.

It should be possible to do the screen just as fast in real-time with going to "done", but this would be much more consistent and maybe save a couple seconds over a 106%.

It's a very small timesave and more about consistency than anything but still worth documenting imo. It's also pretty funny to think about how this super rare version could have something faster.

Here is a video of the glitch:

Here is an album I made comparing the differences between how the versions look on the disc/cover and the serial numbers. https://imgur.com/gallery/G4ro5Bd
