Hmm, yeah, I ran into the LoZ map bug when trying out the FDS. Agreed, there is no substitute for the real thing, but the Neo Fami has worked OK so far, aside from that bug and the whacked sound output (strange pulse channels, too-loud DMC.) Eventually I'll grab an AV Famicom off eBay, but what I ha...

...Are you thinking of CHR-RAM? Quick overview: W-RAM (aka SRAN) is on-cart memory, usually battery-backed, which is mapped into the CPU address space; it's usually used for saved games. CHR-RAM (aka VRAM) is on-cart memory, never battery-backed, which is mapped into PPU address space; it's used to ...

I just got my Lagrange Point cartridge yesterday, and I concur. Not only is it taller than a normal Famicom cartridge, it's noticeably heavier, so I'm almost certain that the sound is on its own IC. When AGTP finally finishes the translation and I have to open it up to make a translated cart I'll kn...

There is a pretty comprehensive document listing cartridge board types for a large number of known NES games. Certain of these board types have W-RAM and others don't; SAROM, for instance, has an MMC1, 128KB PRG-ROM, 64KB CHR-ROM, and 8KB W-RAM, while SBROM is identical except that it lacks W-RAM. A...

Well, there's definitely a lot to be said for pushing the envelope on what's already available (ever heard the Follin's Silver Surfer music? You should.) But it's also pretty cool to come up with interesting expansions, as Lagrange Point and Akumajou Densetsu proved. And as tepples pointed out, the ...

Update: I tried it on another computer, and it worked at least partially; it loads fine from side A, but it either takes a long time loading from side B or it doesn't work on side B. I checked the BIOS settings on the original computer and the parallel port was *not* set to EPP mode, so I'm going to...

Here's a question: I'm daydreaming about a homebrew project which would have VRC7 audio. Easy enough in an emulator, but I'd like to be able to make some game cartridges out of it, and there's no way I'd sacrifice a Lagrange Point cartridge for the silly little game I have in mind. So the other opti...

Um, this subforum is more geared towards NES music; this thread would fit better in "General Stuff." However, here are a few of my favorites: * The Beatles Of course, they're worthy of note because they're one of the most influential bands ever, but in my opinion they're also worth listeni...

Cooper's right; I think the C=64 Programmer's Reference Guide has the best freely available 6502 introduction out there. And yeah, you pretty much do have to test your code on real hardware to find out if it works (which is why I'm in the middle of trying to build an FDSLoadr cable...an approach tha...

Wait until left or right is pressed.
Make the appropriate changes.
Wait until the pressed button is not pressed (or, easier, wait until no buttons are pressed.)
Repeat.

What I'd look for in a devcart is configurable expansion. For example, the ability to switch between one-screen, horizontal, vertical, and four-screen mirroring. I'd also go for an MMC5-style graphics expansion if it wouldn't jack the price up too much. For Famicom devcarts, some form of sound expan...

Yes, but it sounded from your initial post (unless I misunderstood) like you were suggesting modifying a Rockman ROM to include DPCM samples.

Hmm, I remember Rock 'N Roll could change which song was used in which stage, but none of the Megaman editors on Zophar's Domain seem to be able to edit the music itself. If you have a description of the music format, though, that could be combined with a commented disassembly to see whether such a ...

If someone has figured out the Rockman music format and there's enough space in the ROM for altered music data, altered player code, and a couple DPCM samples, then yes, I'd expect so.

I don't plan on ever using any version of Internet Explorer again. Ever. Why not? It started with the fact that it's grossly insecure and bloated. Even if the security holes are as fixed as they claim in 7, it's still, by the accounts in this thread, just as slow and bloated as ever. And to top it ...
