Sniffing of real Amstrad, I listen on some wires of my Amstrad CPC 6128 plus, but I can't access to VSYNC/HSYNC output of CRTC, so I have to buy another model to do this test.In fact you can listen at clock of Amstrad and overclock it after using FPGA DCM component, resulting a clock sequence insertion that permit to insert 4 operations during one tic of real Amstrad, that's it with FPGA DCM you can overclock output Amstrad clock signal for insert more operation, I use this tips for listening signals and saving it in RAM (write, stop write, write, stop write... i'm a perfectionist paranoid...)
