Hello ludde
have you simuluated it in modelsim or other simulator?
I have tried it by modelsim and failed ,because many signals are unkown (x state) during simuation cause cpu stop at some instruction.
and I do some modification by initialize signals in initial statement or during reset , but I can‘t fix it all because i am a newbie.
and also port it to cyclone4 device, after downloading, vga only show boarder, other area is black.
can you give me some suggestion on porting and simulation?
