Well I started hacking WL4 and found some discoveries.

I found some unused tiles in the game that only appear around the file select and new game cutscene.



This is what they look like in game.



A diffrent BG for the file select. It could either be a S Hard reward or a beta BG. I don't know because I never beat the game at S hard and it only appears when you change the hand sprite into something diffrent like the crown or the delete file sprite. oh and the image looks all messed up in japanise and crap because I was testing some things when I took that picture.

Their is also a beta logo for the title screen (this was not found by me, it was found by Racoon Sam)



Most people probably already know about the unused tiles though.

The most intresting thing I found though was the test level, It's surprisingly similar to the Metriod Fusion one, but thats because MF was built off of WL4's engine.

I also found out some stuff about sprites.

Part 2

So far all I know is the X/Y placements, some sprite ID's (which sprite it looks like) and the some sprite behav's (which sprite it acts like)

If anyone wants to see what I got so far on documents ill show them but their sloppy and don't have level layouts or crap like that.

Oh and would it be possible to make a level editor out of the tools on VBA? By this I mean could you make a level editor that reads the data off of VBA's memory viewer and other tools?

Feel free to ask any questions.
