1. Which areas in the first video are "unused"? If you're talking about the weird underground areas with the archaeologist, I'm pretty sure those are just glitches.

2. That "unused" HUD looks like a scrambled coin counter to me.

1: Well in the video it may seem like its just a glitch, but when you open up the map it shows a completely diffrent map then the one that was originaly their. The tiles dont appear but the collision does. the tiles appear if you go to one side of the screen and back so it can refresh.

Is that unused "Warioland" logo still in the ROM or something?

The way I see it, the Metroid games on the GBA are no more than Wario Land 4s in heavy, heavy disguise.

I looked back on Wario Land 4 several months ago and found the TSA data. Didn't document it, but it's ridiculously simple.

If you can pull together some decent documentation I wouldn't mind starting a level editor if you don't have someone else to do it. No promises though, I just feel like picking up a new project and you seem to be doing OK here as far as hacking it goes.
