IC1 is a 7805 or similar: a 5volt regulator, I'm sure of it...
Could well be. I wouldn't have a clue from looking at it. I've only listed part names where I'm sure about them though.
Perhaps if someone manages to dump a retail Pico cartridge we can get more answers.
I've got a couple of carts ...

I wasn't aware of the specs for the MSX; I've never looked into it. Well, reading the thread on the MSX forum, it looks like they had the same problem initially. The initial implementation took 447 T-cycles for each sample, giving a max of around 8KHz playback. Obviously they managed to improve on ...

Wow, that sample is impressive. I wonder if the Z80 in the Mega Drive would be fast enough to make the changes at the required rate though. At 44.1kHz, the Z80 would only have around 27 cycles to update each channel. That's 27 cycles to load the next sample data from the source, and write it to the ...

About the FIFO, the documentation give the max number of permitted CPU access to V-RAM by line (btw, data rate is likely the dma rate) , as well as the max waiting time for the FIFO to execute one command, did you figured the exact slot timesharing between VDP & CPU ? Can we consider taht a VRAM ...

Actually, the dots that appear are the colour of the value you write. Essentially, when you write to CRAM, the single pixel that is being drawn at that moment displays the colour you were writing to the CRAM at that moment, regardless of the colour that should have been displayed. This occurs even ...
