Re: Bus Arbiter and IO Chip Access

(that thread was actually one of the first I think where VDP signals behavior was deeply studied, too bad most of the image links are broken now) It's pity, yes. Feel free to ask me to recapture any of it (or any other) with any of this method: oscilloscope with up to 4 channels (up to 100MHz throu...

Re: Bus Arbiter and IO Chip Access

So, you slow down the system by underclock the MCLK to make more clear capture?

Re: YM2612 clock stopping

Interesting stuff. Did you test TA07 and PCS97 clones too?

Re: simple 68k loop

The DBcc uses only 16 bits for count. So you should use .W and not .B or .L for move opcode. Also, DBcc count until -1, not 0. So, you should load counter with 4 for count to 5.

Anyway, all rookies should read M68000 Programming Manual.pdl before something ask here.

Re: Exodus 2.1 release soon (Now available!)

That's weird because hwm.us.to is my own home server. What kind of error you get when trying to download a file with that link? Also you can try this one ("скачать" = "download"). I figured out what's going on with my home server. My ISP have some problems at IX point. They claim that they trying to...

Re: Exodus 2.1 release soon (Now available!)

Hi! Did you planed to add ladder distortion to the YM2612 core output? We already discover it in the "New Documentation: An authoritative reference on the YM2612" thread. Also, what you think about the Nuked-OPN2 core? My 2 in 1 Battle Toads (and Double Dragon) Sound Trax PD ROM crashes the Exodus 2...

Re: GAS: force move instead movea?

Yes. And usually all questions are resolved when you not just read the PM for CPU very carefully, but make some additional work with this info. For example, datasheet for AVR Mega claims that it have 135 instructions (opcodes), but analysis of AVR core gives only about 66 true different opcodes. Res...

Re: M68k opcode sizes test ROM

Mask of Destiny wow, nice debugging! Now I know, why my cartridge also reboots. I'm just forgot about RESET opcode... So, it must be launched only with dumb ROM cartridge.
