covert nes rom to fds possible?

I would like to know if its possible to convert, nes roms to fds ?

Converting an NROM game (iNES mapper 0) should be a matter of disassembling the ROM and getting it to run from $6000-$DFFF instead of $E000-$FFFF. Other mappers will be harder. But in any case, it's not something that anyone can automate to a point-and-click level unless, say, it's a homebrew that comes with source code.

Just guessing: Did you come upon a Famicom and FDS RAM adapter and intend to use an FDS drive emulator as an alternative to a PowerPak? I ask because I want to know if there's enough demand for FDS versions of NROM homebrew games to warrant my buying a Famicom, FDS RAM adapter, and drive emulator to test on.

I have nes america and FDS RAM adapter.

Picture nes

FDS to NES is mostly doable, but NES to FDS is nearly impossible for a large number of games (probably most of the library).

Most cartridge games expect instantaneous banking of code or graphics, or both, but the FDS needs time to load from disk. This is why it's usually possible to go from FDS to NES; the slow disk load can be replaced by an instant bank swap, but the reverse is not usually appropriate. Lots of games need to change banks several times per frame.

Ok Thx! Is it possible convert nes to snes rom ?

Probably NROM games, or CNROM-like games with only 16K PRG could be made for the FDS easily enough.

The list of CNROM-like games is tiny though:
Argus
Choplifter
City Connection
Goonies
Hyper Olympic Gentaiban!
Kage no Densetsu
Ninja Jajamaru-kun
TwinBee

That is an interesting question. The time and effort required to do that, when you would end up with a game that looks and plays almost identical... seems like it would be a bad idea....but hypothetically... Yes. It can be done....Super Mario All Stars, for example.

I've literally never heard of anyone (homebrewer) doing this. It would be quite a challenge, especially the music. But a simple mappered NES game, minus the music, using the same graphics and MODE 0...possible.

If you were going to port a game to SNES, shouldn't you make use the better hardware...improve the graphics... Move up at least to Mode 1. Improve the music and sound fx. Add some layered backgrounds. Then you'd have a final product that is better than the original.

What game(s) do you have in mind?

115 in 1
Adventure of lolo
Smb3
Smb2 usa (Doki Doki link)
Robocob 2
For play with snes game doctor sf 6

Well, there's certainly this: viewtopic.php?t=13229 ... but I haven't looked at it at all.

Thx

115 in 1? Now I feel like you're just screwing with us.
Smb 2 and 3...just use SM All-Stars.

Robocop 2, Adventures of Lolo...the only reasonable ones on the list (both MMC1). For $2000 a piece, I'll make you SNES versions. (I'm kidding, I can't guarantee that.)

It can be done, but it's not worth anyone's while. See above for $$$ value of the time spent by someone skilled.

If you had $$$ to throw around then you would never jury-rig an FDS RAM adaptor (sans drive) to an NES in the first place.

Give up, move on.

Attach a small PC to your TV and run an NES emulator, if that will make you happy.

There are a few NROM games that have been hacked to run on the SNES. Anthrox made them. None of them support the game's sound and music and in general aren't very fun to play.

There are some NES games that have been made to run on the TurboGrafx 16 and work quite well and are enjoyable to play.

Now running NES games on the GBA on the other hand.... *wink* *wink*

The OP is obviously in a region where 100 NES games on a GBA cart are plentiful anyways... :-/

Aside from Anthrox's NES->SNES conversions, there's also a Korean 20-in-1 SNES multicart of NES games: http://www.dforce3000.de/?uid=46

Rather than trying to emulate the NES's sound, it instead features replacement SPC music including a less-than-faithful recreation of the Super Mario Bros. overworld theme. I dumped the music from it a long time ago here: http://snesmusic.jukor.net/viewtopic.php?f=28&t=950
