Re: Trying to make a NES repro with a "not supported for guessing" board
Roll-Chan 1 is a standard UNROM game, nothing fancy. You might want to try using Nestopia emulator. In the Windows version, open a ROM, click the View tab, then Image Info, there you'll see a simplified mapper info screen. The only downside with it is a limitation of INES, that being it often incorr...

Re: What made UNROM such a popular mapper?
I see, you guys all raise a lot of good points for UNROM, it does sound like it has the most all-around useful features and less highly specialized to specific applications. I'm not sure why I included CNROM, it doesn't have CHR-RAM like the other examples. But while I'm at it, are there any advanta...

What made UNROM such a popular mapper?
This is something I've been curious about for a long time. I think UNROM might be the most common discrete mapper. What drew developers to it over other discrete mappers like AxROM, BNROM and CNROM?

Dragon Wars USA proto
According to nestopia's header lookup, it says Dragon Wars is MMC3 + PRG RAM w/battery + CHR ROM + 4KB VRAM for 4-screen mirroring. Is any of that accurate? If so, I don't think there exists an NES or Famicom PCB with all that. Has anyone put Dragon Wars on a cart before? What board worked? EDIT: Ne...

Making an NES Family BASIC cartridge?
By this I mean starting with an NES NROM PCB. http://wiki.nesdev.com/w/index.php/NROM According to that page, Family BASIC V1 is just an NROM game with 2KB PRG RAM decoded with a 74HC20, also a switch for write protection on the PRG RAM. Has anyone ever tried making such a cartridge? I'm tempted to ...

Re: Thoughts on this "unlock" of levels for Mario NES
Hot-swapping carts isn't exactly great for the NES, but I don't think you'll break anything from doing so. If your NES cartridge has some pins longer/shorter than the others, then that is hotswapping protection. The cartridge chips are a lot less likely to be damaged if the data/address/control/etc...

Re: MMC3A-L
Here:
I only noticed the different MMC3 chip after I converted it to FF3. Should I revert it back to SMB2 for posterity? I didn't do anything with the label.

MMC3A-L
I have a copy of Super Mario Bros. 2 used to make Final Fantasy 3, it's a fairly typical early TSROM-01 board, other than the presence of an MMC3A-L mapper chip. I can snap a picture if needed. Anyone ever run across this MMC3 version? Is it compatible with other MMC3 games? Maybe the L stands for l...

Re: What is actually "baked into" the PPU?
or do the exact opposite and not offer any video memory, using the stock 2KB for both name tables and patterns, at the cost of severely reducing the amount of unique tiles available to the game. No commercial games ever used that last setup, but it is possible. http://wiki.nesdev.com/w/index.php/IN...

Re: Managing complexity by delegating minigames
Wow, that is quite a trip back. I didn't realize NesDev reach so far back. Then again there was Nesticle and it was a DOS program. Thing is almost nothing related to ROMs and homebrew from the 90s still exists today, it's hard for us new guys to understand. Was anybody actually coding demos and stuf...
