Changing What Keys Open Which Doors

[weegetime]

Hello everyone! Just registered today so I'm new to the forum! Anyways I recently started hacking Luigi's Mansion and I want to change what keys open which doors. 
Any help is appreciated!

Thank You!

Woo welcome there bro Well if you started you should know the basics right? Anyways, they're managed by the JMP files. In the game root, you need to extract from map/map2.szp. There's a folder "jmp" inside it and in the folder there are some files, the JMPs, that manages different features and ghosts stats in the mansion. Actually the file "treasuretable" manages it. To open and view the item list inside it, you should like to use InfoFR (http://lmtalk.proboards.com/thread/84/info-file-editor) When you open it in the program there are some lots of items called "key_#". (# for number) If you click in the item it will open info about the item in the right list. Altering the number should in "some" way (for example key_35 to key_33) should open the Master Bedroom. Sometime for me the number is not as expected so it unlocks an unreachable door. Don't know why this happens, I need to test more. (Sorry for the long post too)

Thanks for the help, but I still have a question: when I change the key number and recompile the game with GCRebuilder I open the chest with the key I changed but the chest opens and no key comes out.
Does anyone know how to fix this?

Well, what key you changed? Make sure to check GBH's map and if it is a valid/accesable room from your game's progress.
