I'd like to try, but first I have to learn how to build a core from your sources...

I didn't see comprehensive guide about FPGA programming. Google may help you

Because of author of FPGA64. He prohibit release the code.
Btw, how it's related to SAM Coupe topic?

- Fix disk formatting.
- invert RXMIDI and Tape-IN bits to suit some picky games.
Sorgelig wrote:Unfortunately, i cannot increase CPU speed due to MiST using SDRAM. Unlike in other my cores where i could use FPGA RAM for video cache, SAM Coupe uses whole 512kb for video. So i had to use SDRAM for video. Since SDRAM require significantly longer time than SRAM to access the data, there is no time left for increasing CPU speed (unlike in ZX core where i could achieve 56MHz).
So, the only thing i could do is to disable CPU Throttle to allow CPU work at full speed (6MHz) whole time.
