Galaga (gallag bootleg) arcade repair: debugging CUPL for a replacement daughterboard.

Описание к видео Galaga (gallag bootleg) arcade repair: debugging CUPL for a replacement daughterboard.

This is the first part of another Gallag arcade boardset repair. The CPU pcb was missing the syncbus daughterboard so I implemented a replacement into an ATF1502 CPLD using CUPL language. It didn't come right at the first try though.
