Sony Super Audio CD (SACD) runs a 1-bit DAC using delta sigma, also called pulse density modulation (PDM) or Direct Stream Digital (DSD), at 2.8224 MHz, which is 64 times the CD-DA sample rate. The rate of M2 on a Famicom is almost as high as that: 1.790 MHz. So a 1-bit DAC could be a very good stra...

I guess ability to keep the emulated NES running at the expected speed even on a monitor whose refresh rate is 50 Hz or 75 Hz or whatever else.

On a sufficiently fast PC, I'll agree: stick with bsnes-plus or Mesen-S for debugging. On one entry-level compact laptop I've owned, however, NO$SNS and ZSNES were the only debuggers that ran at full speed.

I ask this toward setting the rules for entries to compos and inclusion of games on community multicarts, among other purposes. It has come to my attention that some things are unacceptably insensitive to put in a video game: Don't make puns or other jokes about Holodomor, Holocaust, other genocides...

In #nesdev on EFnet, tehcloud mentioned nesdir.github.io (source), which uses the last NesCartDB XML as its data source, as a stopgap until NesCartDB can get rehosted.

If this database is brought under the umbrella of TCRF, how would outages (if any) be reported?

NES pixels are two-thirds of a color subcarrier period wide. A white dot that small will carry a small amount of color fringe depending on its relationship to the color burst phase.

If you two were to host NesCartDB, would the origin http://bootgod.dyndns.org:7777/ still be valid in some way? Or would it be a fresh start under a new domain name?

A better reference for a curved Mode 7-style floor is the cylinder-shaped floor of any Animal Crossing game on the DS or later. But I don't know how compatible that'd be with a behind-the-player camera, seeing as the AC games I've played have the camera always pointing due north while outside and no...

I'm favoring nocash's option 2: turn instantly but interpolate more gradually toward the new camera angle. You could try a quadratic ease-in approach, as I did for ease-in and ease-out of the help page in the GB and GBA ports of 240p Test Suite. These equations should help locate the screen position...

As for the Doppler effect, here are things Doom and Animal Crossing have in common: The four-character code ADME. Doom for Game Boy Advance was AGB-ADME, while Animal Crossing: Wild World for Nintendo DS was NTR-ADME. (Spider-Man anyone?) The release of Doom Eternal and Animal Crossing: New Horizons...

As far as I know, the MMC2 (used only in Punchout) is the only memory controller that bank switches in 8KB chunks. Namco 108/MIMIC, MMC3/MMC6, MMC5, Sunsoft 5B/FME-7, RAMBO-1, Namco 163, VRC2/VRC4, VRC6, and VRC7 all have at least one 8 KiB PRG ROM window. Almost a third of NES releases licensed by...

Is there a burn-down list of things you want to fix before the next demo release?

That and 6502 (well, 6507) was the processor associated with the crash of 1983-1984.

If you're using the Pently sound driver, try pently_get_beat_fraction in its "BPM math" module. It returns a beat fraction from 0/96 to 95/96 calculated from the tempo and the declared time signature. Your code can use this to determine how far to move the arrows. Pently also supports callbacks that...
