I have no idea if this will work well in a Windows workflow, so I can't comment on that. No real API is in use here, it's just ANSI escape sequences. As for the other program, there are several which do similar functionality but I wanted this one as a Python script so when I go between a computer ru...

You can use your four palettes to print up to four different colors without having to touch the font in VRAM.

The old version of GCC used with SGDK drives me insane because 1) SGDK spits out a lot of warnings unless you squash them with type casting on resources, and 2) there is no colorization to let you find the one error admist twenty warnings. I put together a tiny python script towards which you can pi...

Got the email, sounds great.

You want to donate one?

I would, but mine isn't available since I'm not anywhere near it. If you can give me a few months, then yeah, that should be possible.

I'd actually love to see a decapping of the Genesis 3 all-in-1 ASIC, if that's available.

For single-direction communication, actually, isn't a voltage divider acceptable to bring a 5V signal to 3.3V using a suitable ratio? It's the single-resistor series drop that presents problems.

Thank you for a very comprehensive look at this issue. I hope this can provide a good reference for developers of hardware for these old systems going forwards. All the cheapo 3.3v Neo-Geo multi-carts slowly killing the SNK ASICs over time are just as unnerving... My Mega Everdrive looks like it has...

If you can read the digital output of an operator, it would be very productive to dump with a logic analyzer the output of the carrier with TL at max, with all modulators silenced, to get a decent dump of the sine table used internally.

I don't know if SGDK has a function for it, but in the end what you're doing is writing to VRAM, and your sprites will show the relevant tiles. If you are doing software rendering you should keep a buffer in 68k memory, draw to it, then DMA it to a location in VRAM. I think SGDK provides bitmap func...

Not exactly. SCUMMVM is already a reimplementation of the original engine. As long as your engine follows the "standard" of what it is expected to do, a brand new engine with no shared code base should still interpret a game properly. It's not wildly different than writing an emulator. Certainly con...

You can do this: const char *strings[] = { "A C String", "Another C string", "A final C string" }; You can then refer to strings[0], strings[1], strings[2], etc and do VDP_drawText(strings[0], 1, 0); VDP_drawText(strings[1], 5, 0); // etc When I use static arrays like this, I like to null terminate ...

You are right, that does look just like it. That's your sprite prefetch image I was thinking of that I referred to earlier.
