He found that D0-D3 and D5-D7 were connected to the PRG ROM data lines; I'm comfortable saying that all eight lines are connected and in order despite D4's conspicuous absence.rainwarrior wrote:Finally, one thing I don't think has been mentioned is maybe check the remaining pins of the 74377 and see if they connect to any of the card edge pins of the PCB (the gold fingers on the edge, both sides).
Not obviously. He found Q4 connects to CHR A13, and the few visible traces in the photo of the underside connect from Q5 to CHR A14 and Q6 to CHR A15. I can't say about Q0-Q3 or Q7.but maybe they're in scrambled arrangment here?
The bad dump he sent me included the reset stub (x: lda #$11 / sta x+1 / jmp $8009). The code at $8009 is a credible init routine, so I have to assume that this bad dump is of PRG bank 1, not PRG bank 0.
I have no idea why the Kazzo isn't working; this is pretty clearly the Color Dreams hardware. But as I linked earlier, a previous person trying to dump a Wisdom Tree game had similar problems.
