Well, IMO theory is "connect according to datasheet" and one more question - how big was memory for programms? And last question - did you used any keyboard?
Thanks in advance
I do not CO, so these tips will never give.
I always give clear and detailed answers. So, let's begin.
First, I will tell about PPU circuit. PPU is required 16KiB memory. I used half of 32KiB chip. What we get? 8KiB fonts and 4 full tilemaps. I used the PAL PPU, so that my scheme is as follows (for NTSC one you must to change resonator and maybe some capasitors near it):
We get the full VRAM version, without useless mirroring. Further, as this is connected to the Z80. With the majority of the signals is clear, R/W should be connected to the signal WR of Z80, but CS connect to decoder of memory map. Memory map of Z80 can be any, invent one.
Something else?
PS To be clear. Everybody knows
CaH4e3?
CopyFamiClone is my device, created specially for CaH4e3. It's like yours CopyNes, but much more powerfull. :3
