I actually didn't write any guides for patching the ELF file. I just followed what was said in the posts I linked to over on psx-scene. It can be tricky to get it working correctly. All I've ever had to do is place the upgrade file and bug fixes in the root of the pendrive and the CB loads the custom files fine for me. I've never run into a problem with it where I've had to figure out a fix.
