Are any of the ROMs 8-bit roms? They'll need to be interleaved if that's the case, and it may be tricky to figure out which is even and which is odd

If you post your files, I or anyone else can look through them and see if any file operations need to be done to make them usable.

Probably gonna skip out on that then and just make a proper NROM socketed cart after all. It looks like that mey be the quickest line after all.

You select the correct ROM size, then click read ROM. It will then dump the contents of the ROM into the buffer, after which you will save the buffer as a file.

Simple - I need to do a demonstration with a little graphical SMB hack I did, but the only cart I've socketed is an FME-7 cart (originally to play Hebereke), and I really don't want to tear apart my SMB cart. Err, I'm a hypocrite - I've torn open my famicom SMB cart, and it's a late one, with glop-t...

NROM games on other carts

Forgive me if this question is elementary, but if I have a game like Super Mario Bros, an NROM game, can I burn it to an EPROM and run it on a cart with another mapper, such as my FME-7 socketed cart?

This is assuming I repeat the data within the ROM to fill up the EPROM and tie high address lines.

My famicom will do that with removed games. After a few minutes, where it starts to become unstable with the data, moving my hand closer and further from the cartridge slot very visibly affects the data. It's a neat theramin-type effect.

Do you have a multimeter? If you do, check for continuity between VCC and GND - it's unlikely, but it sounds like something isn't electrically sound here, as there aren't many reasons for an NES to actually lose power from a cartridge. It's also possible that the Ciclone isn't functioning properly, ...

I'm the one who first posted about the mod after finding that wacky datasheet - apparnetly 1K to ground is the way to go. I've had different results between two seemingly identical SNES machines, however - one shows up perfectly on any TV which takes YPbPr, while another was almost completely washed...

If I'm not mistaken, this works simply because by hoding A+Start as you begin a game in SMB, it does not clear the values in ram associated with the current world. Normally, the value in ram will simply be the world you were previously in. By starting another game, which uses that address for a tota...

I would like very much to order one of these. I haven't had a chance yet to read through all there is to read; is it publically available yet and payable via PayPal? Also, how is compatibility with VRC6 and Sunsoft 5B external audio? May we possibly have a demonstration of the functionality? I am pa...

Well, I've dumped all the roms for this. Looking in a hex editor, a few do squarely correspond with some real Sexy Parodius ROMs. If anyone is interested in the images for some comparative work, let me know.

pichichi010: I appreciate the offer, but we should be set (I believe the server we'll move to is running a Xeon.. just total overkill, I'm sure). mikejmoffitt: No worries man, Parodius is closing but NESdev isn't. Just means the address will be nesdev.com rather than the classic nesdev.com. Alright...

This is all an unfortunate read for many I'm sure - I recall reading through nesdev for most of my middle school times years ago, and having only recently rediscovered it to find it's closing is disapointing! I have a server lying around on a fairly beefy stable enterprise-level connection; would it...

I'm pretty sure the music is simply because of how they handled audio - the entire M68000 that normally controls audio is entirely missing, and it seems they implemented their own hardware to listen for the audio cues and respond appropriately. Of course, this solution relies on shitty sample playba...
