I think it just does ISA mods and you don't need an extra program to do that. It has the muyu ISA bundled with it which is the oldest one (and which has a higher failure rate). If you're going to do an ISA mod it's better to just run the cbrom command with one of the updated ISA's.
Not at all. It was a simple overflow (a silly vb thing where uint = byte * byte must be written as uint = byte * cuint(byte) - otherwise problems.... which is daft!). The tool handled the 4 extra bytes fine! Andy
1. The Modded file is 2005.ROM (this one has the slic) and is EXACTLY 524,288 bytes (512K). Extract the file using WINRAR 2. Modded bios is 2005.ROM Let us know how it went - Good luck!
