Ok, now, from what I can gather from it...
This is a distribution edition. It is just a copy for us to play due to ZUN laws.
However, I am EXTREMELY baffled by- one, the wrong stage music, and two, crashing at mid-boss Aya.
My theory is... that Aya's cut-in is not in the img files, when it is suppose to load it. wtf.
EDIT: Cheat Engine works! Thanks Drake, although the system is extremely gimpy. You can't set it at 4.00 and make it stay that way. The game still sees that as a death, puts your back to 3 power (and so on...), while the power bar still says 4.00.
To do an easy fix, simply set the value to 3.99. Just grab the Power item every time you die, and tadda! Full Power.
If you bomb however... it will "fix" itself to 3.99 again. Oh well, I'm doing this to practice anyways, so why bomb?
