GAAAAH! I need some minor/major help on a big project

[Katakiri]

Okay, I really wanted to keep this a "hush hush" project but I ran into some walls (buildings actually) and now I'm stumped at what to do.


I'm replacing Pokemon Stadium 1's background with Pokemon Stadium 2's.

Problems:
-PS2's main platform texture appears in transformations with dips in the stage as shown here:
(Very outdated pic) See how there's wood in the middle where the dip is?
The stage glitches badly everytime I try to hex it out.

-I can't move the buildings/monitor back to where they should be. (Don't know how)

-I can't resize the stage so the ledges look right. (Just don't know how)


Other than that the stage plays fine, even on wifi.


The only solution I can think of to get rid of the regular PS2's green/pokeball stage texture is to make it transparent. Which I'm not sure if anyone knows how to force polygons to use transparent textures correctly.

Help would be MUCH appreciated.
