FWIW, I think it may be easier for some (including myself) to do a mapper primarily in an HDL (Verilog or VHDL), rather than using only schematics. Maybe for disabling WRAM, you could fake it by emulating open bus for reads of disabled WRAM - detect the high address byte of the read and force that i...

I noticed how blargg's 3-phase NTSC demo turned white pixels into cyan, magenta, and yellow. I tried experimenting with this using a single grey palette ($0f, $2d, $10, $30), and it turned out to be a pretty decent looking palette. You can see here . Download here . I think I now see why blargg sugg...

Nope - the game doesn't even read $2002 for anything during the level-intros.

Mickey Mousecapade uses CNROM. So I'm guessing the problem has nothing to do with the mapper - since all CNROM does is CHR bank-switching, and it looks like the pattern tables are correct.

There's a walkthrough for the SFC remake , so I used that. It did help me learn a few bits about the plot, but unfortunately, not everything is completely compatible with the FC version, it doesn't say anything explicit about the plot, and it only shows one path, but there are a few extra possibilit...

*SPOILER WARNING* : Be very careful here, if you didn't finish the game, DON'T read the list and the stuff under that. Recently, I finished Metal Slader Glory ...it's one of my favorite NES games! The music is awesome - but IMO it has the best NES graphics EVER. I mean, it looks so gorgeous that it...

For some reason, it won't work when I put it inside a link, copy the address into your browser bar.

Or...go here and click on "Here you go."

I can't find baby mario (bio miracle baby upa) or something. Know where to find it? ROM sites probably have it - If you can find FDS files, you can probably just find a copy of the game. "Bio Miracle Bokutte Upa (J)" or similar under NES is Konami's official port of the FDS version to NES...

Buzz & Waldog is not even findable on google anymore. Buzz and Waldog is an SMW-clone. While it stole its sound engine and some of its sound effects from Konami games, it has original music. The game has simplistic, cartoonish graphics, but they're very colorful and are well-executed. The contr...

I assume you are referring to FRAM...I checked the schematics and it appears that it's clocked by "nesclk". However, it's really strange, because for the symbol definition and schematics for FRAM, the clock is labeled "m2", but "nesclk" is being fed into "m2" ...

I don't have a PowerPak yet - maybe until Christmas or my birthday...but I might want to try create a mapper anyway, heh

Where's the PowerPak's own clock, though? I can't see it anywhere for some reason...

Technically, the FPGA connects to 13 bits, but not in the way to support 8KB, though - bits A10-A18 are missing and supposedly utilizes the PPU's bus on the PCB. I do have a question regarding a few of the CHR RAM pins that are connected to the FPGA - Why are pins A0-A2 and A10-A11 pretty weird? I c...

Speaking of Nintendulator, Quietust recently updated the emulator, see here. There's also a post in his own QMT Productions forum here. So even from that bizarre drama, Quietust did not seem to quit NES development.

EDIT: Assumption removed about Quietust leaving the Internet.
