1. Copy and paste all the files from the gzip folder into: C:/documents and settings/admin
2. Copy and paste your kernel.bin file into: C:/documents and settings/admin
3. Click on Start, All Programs, Accessories, Command Promt.
4. In command promt type in: ff7dec d kernel.bin
5. Press enter.
The kernel bin will then be decompressed into several seperate files. Look in Qhimms wiki to find out what data each file holds. You can edit each file using a hex editor. If you don't have one, there are several free ones available on the net, just google search it.
Once you've done the editing, you need to compress all the files back into a single kernel.bin file.
6. Open up command promt. Type in: ff7dec e kernel.bin
7. Press enter and your new kernel.bin will be created!
EDIT: Got rid of the typo - Hes editor - lol!
