Those ROM images aren't copyrighted, are they? Because if they are, I'm pretty sure it's very against the forum rules to post them here.

P.S. If you don't get this note, let me know and I'll write you another.

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 made to run on a standard NES.

let me explain:
backgammon has vt02 graphics.
all we need to do, is to cut out the adpcm.
and the other games can do vt02 but with weakenend palletes

Yes, they are copyrighted:

I have saved myself the trouble of looking up the other games, but I expect them to be copyrighted just like this one.

There is EmuVT, which is based on NNNesterJ, it will probably run the games. But EmuVT's accuracy for the base NES console seems a bit spotty, as it is based on NNNesterJ, which fell behind in accuracy as emulators improved.

so maybe, we could implant the vt03 compatibility into pocketnes on gba.

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 Windows 10 because of forced updates and telemetry, but I cannot see why people still would want to use XP.

The biggest difference between the "Windows XP" toolset and the non XP toolset is how thread-local storage is implemented. Vista and onward use one of the segmentation registers to point to thread local storage, while XP and earlier do not. So any time a program uses thread-local storage, it will crash on XP with an access violation.

The "Windows XP" toolset also supports Windows 2000, and earlier operating systems, it's the traditional Win32 that was established from Windows 95, 98, and NT 4.0.

I figure it's worth building on that toolset just because it also improves compatibility with Wine.

So again, if you're not making use of thread-local storage (will get a slight boost with the non-XP toolset), and don't need the newest C++ standard, the XP toolset is just fine.

actually the error of nintendulator is the "exe is not a valid win32 application"

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 else demanded Windows XP compatibility. It's still a "no" from me.
