Commodore 64 sound emulation with PIC32MX

in dev boards by Ian | 2 comments

A few days ago we asked about open source projects you’ve tailored to suit your own needs. Markus writes:

I don’t know if it counts, but my story is this: There is this PIC32MX open hardware board named CUI32 for which I managed to get some SID (Commodore 64 sound chip) emulation code to compile and run. The problem is, that the PIC32 used has “only” 32 kB RAM whereas the unmodified emulation code uses more than 64 kB RAM. To get it working for all SID tunes, I changed the design to use a PIC32 which has 128 kB RAM, and also made some improvements to the pin headers, USB connector placement on the top side, etc [4]. I am currently trying to get all the parts to build this improved version.

    Very cool :)

    I would assume the stock of genuine SID chips may be getting smaller, since from what I know people who use them seem to go after certain revisions for that certain “sound”, really coming back in fashion of late though :D
