FPGA Tuning C64 SID Jeri Ellsworth

Use an FPGA to tune a secondary SID chip to give the C64 a pseudo stereo effect. This demo shows how you can play ordinary chip tunes as if they had stereo channel differences.

Isn't there some way to modify an existing C64 without ripping it apart or attaching some techno gizmo to it to get stereo output?

[jeriellsworth]

@HoneycombAgent This is a little different than just adding a second SID. This converts mono tunes into pseudo stereo. It could be made into a cartridge.

Sorry, but isn't it overkill to use a FPGA for just producing stereo ?

[jeriellsworth]

@Antitrack The idea is to pitch shift the second SID or other similar effects.

Too much stink and testosterone in the comments hehe !! The JTAG bit was very useful , always wondered how FPGAs are programmed.

@Antitrack LOL ... you're so not a geek :-P Nothing is overkill to a true geek. :-D

@anilksolanki i think he may contributes with his genitalia. Good enough heh

Sorry if this sounds sexist or not focusing on the point of the video, but that's insanely attractive :3

I guess this is a good way to hack sounds that are played quickly.

But controlling the chip itself is very simple.

At 3:40 did you actually press the button and detune the right channel? It didn't look or sound like you did. Very nice work btw explaining some of the basics of the FPGA tool chain.

Hi, I am new to this channel. Can someone tell me what the "Fat Man" does? I have watched a few episodes of "The Fat Man & Circuit Girl" but I can't figure out what the "Fat Man Contributes". Many thanks. I love the channel Jeri, entertaining & educational, perfection.
