Hey thanks for mentioning this. I have a question:

I changed the

#define CBM8580_FILTER_FIX 1

to

#define CBM8580_FILTER_FIX 0

to disable the filter fix (I am using the 6581), but after reassembling with no errors, converting the hex to sysex, and programming the chip, I don’t get any sound out of my sid. If I change it back to 1 and do it again, it works fine.

Is this what you did Stigmata?
