Removing selfboot

Is there any way of removing the selfboot sequence from a game (eg: tony hawk2), so that I can use it with the standard utopia bootloader?

Any help would be appreciated.

1) use hex editoR to search the boot.bin that contain

5A2E 0000 0100 0000 4344 3030 31
change it to
A600 0000 0100 0000 4344 3030 31
save it

2) Burn all g**a data files at ISO 9660 mode1
