It is only large because of the included "song". Also if it produces any sound somehow (it should, but it does not work for me with VICE) it may sounds poor, since the timing information is not so correct yet. Anyway, if I ever can make it hearable, I would clean the rest of the program and give the source, just first I like to make sure it works at all: at this point I am not 100% sure if it is my fault that it does not work or not. Unfortunately I have no real hardware (I have C64, but not the cartridge) that's why I would need VICE to test. The heart of the code is just this: loop: [...] STA $DF40 ; YM register select, register number in A now [...] STA $DF50 ; write the register data, data in A now [...] Looping ... There are enough instructions between the two STAs and between do the looping, so the needed minimal delay after YM register select/data write is provided in this way.
