Re: Modding FPGA64

Hi,

nice to hear about such a thing. The pinouts should all be in the
schematics of the C-One, which you can find under www.c64upgra.de.
Expanding the color ram to 8 Bit should be one of the easier graphic
extensions.
Using all 8 Bits of the color ram as 256 color index might be another
easy extension, right? Just an idea...

Regards,
Andreas

Hi, A little problem with the C-One is that the 65816 is sharing the bus signals with the 128K SRAM. So for enabling the 65816 it would be easier if the SDRAM...

... Well, once I'm done modding, the core won't have much compatibility anyway. I'll have a try at using the SDRAM then. ... Ooh, I hadn't considered that....

Dear all, isn't it possible to use some space in the upper area of the 128k RAM for the color ram? I think, the upper 64k are only used as ROM area, right? ...

Hi Andre, ... There is about 40k free in the SRAM. Putting the color ram there takes 1 extra memory cycle so the VIC-II code needs to be changed so it allowes...
