Re: Strike Wolf (MGC-014) (Unl) [!] zapper
It mostly works in BizHawk (accuracy is a little low but generally correct.) you have to plug the zapper in port 2. WARNING: I don't recommend it though, it started hurting my eyes only after like 1 minute of playing. The flashing is quite a bit worse then in other zapper games. bizhawk。。。。not work...

Re: Difficult-to-emulate lightgun game: Top Hunter by Asder
All emulators that have lightgun support can run Duck Hunt and Hogan's Alley, but there are some tough-to-emulate light gun games from unlicensed publishers that pose a greater challenge. The most difficult seems to be a game called "Top Hunter", which only exists on the Asder 20-in-1 mul...

Re: Super NES controller support in NES emulators
I have added this controller to BizHawk's NesHawk core, and it passes the test.

VRC6 Test Rom and hot swapping carts
A while back, I added (what is believed to be) fully correct VRC6 support to Bizhawk, including the special PPU mapping modes. I also created a test ROM to verify that my behavior was correct, and asked for people to run the test rom. I had someone run the test rom on an everdrive, which showed that...

Re: about the APU raw samples and the real playable samples
The downsampling isn't done by picking out individual samples; downsampling algorithms take more than that into account (you might think of it as sort of averaging them all together, but it's more complicated than that). The Nyquist limit is still there though. If the final audio output is at 48khz,...

Zapruder calibration
I recently added zapper emulation to Bizhawk. A few games that I've tried seem to be working, but I want response to be as similar as possible to how it was on real hardware. I tried zapruder, but the docs for it don't seem to give any indication of how hardware should respond.

Re: Should I disable rendering during vblank?
The horizontal copy might be delayed by a scanline if rendering is disabled at x=257, causing wrong horizontal scrolling on the first scanline of the picture (which is well within NTSC's overscan). But it'll fix itself by the second scanline, and in any case, it overwhelmingly likely won't affect s...

CHR /OE vs /CE
As far as I know, the standard CHR ROM hookup is: PPU A13 -> CHR ROM /CE PPU /RD -> CHR ROM /OE Or, when a CHR ROM has only one /CE: (PPU A13 + PPU /RD) -> CHR ROM /CE As outlined in this thread: http://www.famicomworld.com/forum/index.php?topic=8671.0, some carts made for clones connect the followi...

Re: New NES/Famicom-clone
So is it a FPGA? Or innards from a real NES (or some clone) with an RGB mod hacked on?

Re: UNROM 8 IN 1 Multicartridge
Yeah, that's what I needed.
The board is supported in Bizhawk as of r6204.
Here's a UNIF header that should work:
http://www.mediafire.com/download/xt2c9 ... header.unf
Concatenate the exactly 1MiB of PRG rom on the end of that, and it works in Bizhawk.

Does the second 74'161 clear on the reset button or just on hard power?

Re: UNROM 8 IN 1 Multicartridge
Taking a look over this, I could easily add it to Bizhawk. It would be UNIF only though.FARID wrote: It would be nice if someone can emulate this cartridge.

Re: Cartridge slot pin out directions
I personally like labeling the cart edge busses as "PPU" and "CPU" instead of "CHR" and "PRG". It's more compatible with how mapper chip pinouts are typically labeled. CHR is really a misnomer here anyway because that bus carries both CHR and NT.

Re: 128 KB prg rom
There are some 28-pin 128KB mask ROMs in being used as PRG-ROM in original Nintendo carts. 128KB CHR-ROM never comes in 28-pin packages though, for some reason CHR needs more control lines. Third parties did it from time to time: http://bootgod.dyndns.org:7777/profile.php?id=2308 (I can't figure ou...
