Re: Starting games with two controllers and a microphone
This is the game crashing while running in FCEUX. There's some kind of emulation bug happening here. It has nothing to do with accessories, or special ways to start the game. Merely, the game just crashed. Try another emulator. It seems to work fine in Mesen, but that emulator can be slow. Try Virtu...

Re: Conference speech about nesdev, I need your help reviewing it
(note that my previous post was edited) "Lack of Writable memory in console" is ridiculous, that's just the wrong word there. It should be 'non-volatile', 'persistent', or 'permanent' storage instead, as the internal memory is quite writable. And the "No negative numbers" thing i...

I think users might prefer the native Win32 file dialog for picking files.

Re: Have you seen such a video mode?
Speaking of unconventional video modes or hardware, there's the FM Towns computer.
It can display a 640x480 monochrome Kanji layer on top of 320x240 256 color graphics.
Does this count as the "combined text and graphics mode" idea?

Re: Modding NES mini Chinese clone
Is it a Nes-on-a-chip or an emulator console?
If it's a NES-on-a-chip, you'd need a way to get to the actual flash memory chip, and that won't happen without soldering.
If it's an emulator console, there might be a microsd card just sitting there.

Bad cart connection makes NES display all 256 tiles
I saw a game have a bad cartridge connection, and it looked like it was treating the low 8 address bits of a nametable tile fetch as the nametable tile byte itself. Would any specific pin being connected badly cause this fault? Screenshot: faria-bad.png It also went in and out of glitchiness, exampl...

Re: As a kid, I never understood the difference in time...
Mario 3 came out in Japan really early, like 1988. Super Mario 2 was made after Super Mario 3 just to have something there for the US before they released 3.
Re: ArkNESS
Looks like the program isn't processing windows messages while the Open File window is open, combined with using DirectX, this is seriously bogging down a system. It takes Windows a whole second to process a single keystroke! I can see the main window become a Ghost Window while the Open File dialog...
Re: ArkNESS
Getting an access violation exception. A NULL pointer getting deferenced.
Happens soon after a call to SHCreateItemFromParsingName, but that might not necessarily be the location of the error.

Re: Drawing attributes vertically
I would keep a copy of the entire attribute tables in RAM, it makes it much simpler when you want to update them in VRAM.

Re: Drawing attributes vertically
Either set the address every write, or use 32 increment mode just to get two writes in.
