Hi everyone!
Thanks to Leon's incredible perseverance, I was able to test his latest (S)GC compatible update to the basic CPLD-based 8301 ULA replacement.
I'm delighted to report that it works a treat on my (Tetroid cloned) Gold and Super Gold cards once reprogrammed!
I am yet to explore the optional 15-colour (RGB-I) mode and will share my findings here in due course.
Thanks again, Leon!
