I thought I would put this in Introductions even though I'm not quite brand-new here, because this introduces my first successful speedrun of Columns III! I did it in about 30:17, so I've got the half-hour barrier to go after now for level 2 of speedrunning Columns III (level 1 was beating the 34:45 time, the only one recorded in America.)

I actually "double-recorded" it with a commentated version here:

Here is the uncommentated version with the emulator's recording:

So I thought I would post this here while I wait for approval from @SegaJunkie.

One possible technicality I could get this rejected on is that I paused emulation BEFORE timing started to move the window on my screen. I never paused during timing or afterwards, though. Some very competitive games have rules that require the run to be from a hard reset.
