r5918 /src/mess/drivers/pc6001.c: [PC6001]: Rewritten the video emulation from scratch, ASCII's AX-1 Demo now displays correct gfxs








PS: any help / info / suggestion about how to handle these ADC'ed tape images in MESS is appreciated.

is there any info on the specific format?

usually, we convert back tape formats to wav at loading time (not always easy, but then you can use core functions to handle everything else wink ), but of course you need to have enough data to recover the original wave (or a square wave that a PC6001 could not distinguish from a real analogic one)

pc-6001 .cas format is just raw image in digital format that can be hooked up like a ROM sequencer in MESS (like is currently doing right now).

yet, given the bad experiences with some old drivers like cgenie or trs80 (and commodore tapes as well), I think it would be better to try converting the bits back to a wave then to feeding bits directly in the memory...

I'll take a look to the format once I'm done with NES mappers, later this week (of course, if you haven't already solved the issue)

r5920 /src/mess/drivers/pc6001.c: [PC6001]: Implemented 128x192x2 support, most games uses this mode





They are actually static images, they hangs due of a missing irq (vector 0x06), I should study what this irq does and implement it...

Since the version 0.133 I have problems to load harddisk images (.chd) on pc or compatible drivers like pcmda.
The .chd files are already updated with chdman.
As I said, the last working version was 0.132
