Hello!
Well, what you have to do is:
1. Get the QG8 datasheet, and locate the place where the registers and interruption vectors are, and make a copy of the original folder. You will work on the copy (or the original, whatever, just let one unmodified just in case
)
2. Open the file in the beekit project in wich interruption vectors are (don't know the name, but patiently you will find it) and replace the vector addresses in that file, with the addresses on the QG8 datasheet.
3. Do the same with Port Registers, Timer Registers, and any other module.
4. In case your QG8 has less ports or pins in a port or modules than the QB60, delete any references made in the main program for those pins or ports or modules.
5. Compile again, debug, and repeat if needed, until your application works. ¡Enjoy!
