While not quite "skipping", I've found the files you can edit to make the intro less annoying. Either by not appearing at all, or replacing it with your own intro.

Because of the way the files are loaded, I'm assuming that you'd need to edit the executable to actually SKIP it (not waste time).

Since all I care about is the interruption (content), and not time so much. This solution works well for me, and wanted to share it, in case it works for you too.

contains (the japanese voices for):
00000000.wav = "sega"
00000002.wav = "puyopuyo tetris"

the file itself can be deleted, or renamed to "title00_bank.xwb.old", and the sounds will no longer play. The game won't crash either.

For the english voices, it's title00_bank_e.xwb

ALL of the files containing "title" in this folder DO say the same thing. But for me at least, aren't played during the intro.

Need to be replaced with valid files (not deleted, or renamed), or the game will crash.

I've had luck with GIMP and the .dds plugin, and editing the originals (with the same canvas size) to just be black instead.

also seems to be loaded for some reason.
ALL of the files in the logo folder basically contain the same things, just packed in different ways.

This guide is super helpful, and has pretty much all the stuff you "need"

Extra tools:

Windows Process Monitor[docs.microsoft.com] (to help find files being used faster. also not to be confused with process explorer)
GIMP[www.gimp.org] (free image editing software)
Gimp DDS plugin[code.google.com]

.wav = basic sound file
.dds = fancy picture file (you need additional tools - in the above section - to view or edit)
.xwb = archive / compression (like .zip) file that contains other files. In this case, .wav files
.narc = archive / compression (like .zip) file that contains other files. In this case, .dds files
