NintendulatorNRS and Mesen run it as a standard NES/Famicom. I do not know about any other emulators, but expect them to not react to that field at all.

Re: New hardware and the INES 2.0 header

I assume we are referring to the expansion port at the bottom of the front-loading NES? How will the sound device be used with top-loading NES or Famicom consoles? But that depends on what signals the cart sends down through the EXP pins to the expansion connector. But if its functionality requires ...

Re: New hardware and the INES 2.0 header

The "$4016/$4017 devices" may not be set into stone, but I would like to know how your expansion sound device is interfaced and connected to hardware, then. I would prefer to just define additional entries instead of allocating bits, because once you have allocated a bit, you have effectively alloca...

How difficult is it to decap and analyse a globtop-only ASIC, such as J.Y. Company's ASIC?

I don't even know what that is, and I disagree that I need to do anything for you.

Re: Make a VT game work on nes

I am not so much worried about using the Windows XP toolset as I am about installing it, just to satisfy a single user who persistently makes rather extravagant requests across several forums, including this thread. I have not had people report issues with regards to Wine compatibility, and nobody e...

Re: Make a VT game work on nes

could you please give the new nintendulator nrs windows xp compatibility? I would have to go out of my way to install the Windows XP Platform toolset. Too much trouble for too little benefit, so no. You should not be using XP these days anyway. I can understand people not wanting to switch to Windo...

Re: Make a VT game work on nes

Backgammon and Wave Tiger are VT369 games, running the main CPU at 5.37 MHz and requiring a second CPU for sound. The others are VT03 games, requiring VT03 graphics and a custom ADPCM sound chip, notwithstanding that you changed the header to incorrectly denote VT02. None of these games can ever be ...

Re: mmc3c decap and trace

Strange scanline counter, yes. There is something new to be found out about its behavior, whereas the MMC5 (thanks to your efforts) is fully-understood, as far as I am aware.

Re: mmc3c decap and trace

Very cool. I am not on Twitter, so if he takes suggestions on what chip to decap next, might somebody suggest to him to decap the Tengen RAMBO-1 next?

Re: iNes mapper 159 with 512KiB PRG

Alternatively, because this first Knight Gundam game only uses 128 KiB of CHR-ROM, you could connect the LZ93D50's CHR A17 pin to PRG-ROM A18. But then you would have to modify the game code accordingly. But that would switch the entire $8000-$FFFF CPU address range, without the fixed bank at $C000-...

Re: City Figher 4 with ext audio (Mapper 266)

I speculated on the wiki that doing so would allow them to add a low-pass filter to make the grungy PCM sound less objectionable.

No, I only debugged the game's code and tried to draw plausible conclusions. 8-)

Re: dragon ball revival of the dark lord, JumpA or Doragon2 donnor board

If FCG-1 supports 256 KiB already, what then could be the difference between FCG-1 and FCG-2? So far, we only know the difference between FCG-1/2 (submapper 4) and LZ93D50 (submapper 5).
