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. ...

Does anyone know if there is a list of games that contain w-ram anywhere? Thank You

I know one of the guys that sells reproductions makes adds his own batteries onto the final fantasy 3 carts inside of a holder. Thats what I want to do

Well with the TKROM I would have to use 2 games just to make the one game, which I do not want to do really. Plus I would like to learn how to do the batteries as well. Thank You!

I cant seem to find any information about how to add a battery to a TSROM cart (for games such as Final Fantasy 3 for example). Are there any docs anywhere on how to do this? Im trying to make a Final Fantasy 3 but do not know how to battery save it =( Thanks!

This would be SLROM correct??

Is there an alternative way to wire SLROM boards? I have a rom, it is MMC1, It splits into 2 files, prg/chr, so it is a SLROM board.....When I wire it up by the directions below, The title screen works fine, but when you start the game, the screen will screen will just go blank. The rom works great ...

I have designed a box for my game, but I have no clue where to get it printed up at, anyone have an idea? I have found a few places online, but you had to order 500+, another was 1250+. Thanks!

I tried, hince, thats why I am asking. Im not a techie.

Would it matter if it was a CNROM-256-05 (Tiger Heli) or a CNROM-06 (Back to the Future) or is there a difference??

found another copy that says 3 - VROM switch ???

This is what it says in cajoNES anyways. (or the rom I have is) Is this not a correct one?

To convert a UNROM (must be 128kb) to AOROM (must be 256kb) you must simulate a static bank by dividing the game into 16kb blocks and append the last bank (bank 7) to each of the banks including bank 7. The file size should be 256kb. .....you lost me. lol Im not that technical into these type of th...

I know you can convert an Unrom/Mapper 7 cart (7 - 74HC32). I am attemping to make a Goonies 1 cart. But the problem is, There is both a PRG AND CHR file with this, but the AOROM conversion only talks about the PRG chip slot. Any clues? Thanks Bunches.

Im looking into purchasing some of the ram chip's that are im SMB3, but every place I find , you have to email them for a quote on prices, or have something like a minimum order of 150. Anyone know of a place to purchase these? I tried digikey and jameco

Thanks
