Well, if port will be released in source code, i will try to port again. Original version uses SDRAM.
Of course, I will release the modifications. Unfortunately, I don't think the MiST port could get an advantage from them because I replaced the 16 bit SDRAM controller with an 8 bit SRAM controller, and the MiST needs a SDRAM controller. With this modifications the core would be harder to port than the original one.
I also tried to make a port for the Altera DE1 board, but it didn't work at all. I think the Quartus software can't implement correctly some parts of the original design.
