Hmmm...
Well, it started to work in oldskool amp'd, but then it just stood there blank on the black screen, so I figured I made a mistake and redid the whole thing. Holy Cow! My UT game works in fullscreen now! (HP Pavillion with intel810 gfx, running WinME, a true nightmare!!) I could not even run software mode in fullscreen until now. In fact I can ONLY play it in fullscreen mode now. Still no DirectX though (It actually works now, but is totally unplayable). Sad part is, oldskool amp'd got wiped off my computer, so I don't have access to Unreal, RTNP, or Legacy anymore. Guess I have to redownload everything, 'cuz I don't know how to fix my .ini for it.
Or give it another go, and see what miracles happen this time!
Except now UT Ued won't allow me to edit the UPak

.
Also: all of the default properties code caused errors, so I had to comment them out to compile, including some code. EX:
<ERROR: Unexpected defaultproperties in UPak.SpaceMarine>
:redeemer:
