Hoi. :3
Thank you, Bonesy. Thanks to you and your supplied save, I diagnosed the problem successfully. The culprit was not any of the patches I suspected. It was Soul Saved B, for reasons I currently don't understand. I've removed it for the time being. The current comp patch doesn't have the softlocking problem and should be good to play.
Removed:
Soul Saved B (Leet Sketcher) ... I'll put it back when the problem is fixed.
Added:
Precious Jewels (Leet Sketcher) ... Despite my claims to the contrary in the readme file, I never actually added this before!

Now it's in.

Happy patching. ;P
(Also thanks for all the kind words directed at this "project" everyone.)
EDIT: It seems I have a poor understanding of the Soul Saved readme. It doesn't say what order I should be applying the patches in. I must have used the wrong patch. I'm not entirely sure how to resolve this, but I think I can figure it out. Maybe. >~<
EDIT 2: Nope. My attempts to patch in a different order are still failing. So I need to leave the Soul Saved B patch out of the comp until something is figured out.
If anyone finds any other bugs, please be sure to let me know. You're helping the patch writers, too. :3
