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 ...

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?

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 ...

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.

Re: SEGA IR wireles joypad

The IR problem is in unidirectional. So, all emitting devices doesn't to know about each other. If they can be bidirectional, they can be in passive mode and answer only when base unit ask any single device wich will have unique address (callsign). All arbitrage done by base unit and no colisions ...

Re: SEGA IR wireles joypad

Sure. The joypad sends its own state every X time. Always when any button is pressed. The base reads the joypad state and convert it to state of internal joypad, that physically connected to the console. If no state was recieved by IR after X time (plus some time) the internal joypad state force to ...

The end of the ROM should be 003FFFFF =P
The ROM windows should be $000000-$3FFFFF, but ROM itself not required to be up to $3FFFFF.
