Has anybody tried making a program that repeatedly polls the microphone and writes the output to D6 of $4011? I wonder whether the microphone circuitry is sensitive enough to read the actual audio from the mic, or whether it's just a level detector like the mic in the DK Bongos.

0.960 when?

I don't see any releases newer then 0.900 in Nintendulator's file list nor newer than 0.950 on the web page.

Emulators were written by humans, and humans are susceptible to errors. That almost sounds like a defense of Nesticle :) Asking for the "best emulator than X" is quite an harsh question. :( However, "which emulator in the experience of other NESdev members has fewest differences from the NES hardwa...

The easiest and most realistic way to move bullets in curves is to keep fixed-point velocity and displacement vectors for each bullet. Then each frame perform Euler integration: add accelerations due to force (gravity, wind, etc) to velocity, add velocity to displacement, and take the integer portio...

Which emulator for dev testing?

I don't want to become the victim of assault and battery for having published an iNES file that hasn't been tested on real hardware. Until Squeedo comes out, I can test NES ROMs on real hardware only by sending a copy to a trusted party on this board, but the logistics of that method limits such tes...

Re: scanline "detecting"

Sprite 0 hit: 1.does it work ok if the sprite has low priority? You mean the "behind" bit set? Yes. 2.if the left 8 pixels of the bg are disabled, does it work (I gess not, because of the "nothing to colide with" thing)? Visible sprite has to overlap visible background, and it can't be in the right...

Which Koei games use MMC5? Those would be the most likely to use the split screen.

Camerica can probably piggyback as a variant of UNROM, and NROM is the special case of CNROM with the upper CHR address lines not connected to anything.

125 in PAL, 150 in NTSC. The NT2 replay code emulates the PAL rate on NTSC, but it distorts arpeggios while it's at it.

What I'm saying is that the NSF players out there for Linux right now... well... suck. Are you referring to the fact that Festalon was discontinued?

...yeah. I mean, I could come up with an orchestrated version, but I'd rather have the bloopy MIDI; in some cases chiptunes have become an artform all of their own and really don't imitate any other instrument. If your machine can play MIDIs, then either it has a working wave-out or it has an Adlib...

I suggest we try every known homebrew ROM on hardware and on an emulator and document what goes wrong on either side. Also tell which commercial ROMs don't work on the newer, more accurate emulators, where the difference isn't one of mapper support. Then we'll know where to look for differences, wha...
