for some reason, when I export an FDS song as .NES, the FDS fails to play, so I end up with a melody, but no bass. Does this happen to anyone else, or am I just being a complete retard?

Also, I've tried with and w/o the PAL flag and the emulator used is VirtuaNES

Disk System ROMs use the extension .FDS; I don't think .NES files support FDS audio. Dunno if there's a way to create an FDS file from FamiTracker though.

Yeah, the .NES file format I don't think does FDS. They reserved mapper #20 for it, but I don't think it was ever made part of the format.

Also, in NSF, some emulators will disable all audio expansions if you set the PAL flag.

Maybe you can find some sort of NSF2FDS utility?

The only reason I tried was because I wanted to play music on the real hardware, then I found [url=http://nesdev.parodius.com/bbs/viewtopic.php?t=4442&postdays=0&postorder=asc&start=0]this.

It's an NSF Player for the PowerPak, which I think is absolute genius. I have yet to use it, for my PowerPak, and OTHER NES haven't arrived yet.

Does the PowerPak do sound expansions?

Yes - VRC6, FDS, and N106 expansion audio is supported (but not VRC7). But you can only hear the expansion sound if you solder a resistor between some pins in your NES.

FME7 is also availble, but only while playing Gimmick! and not while listening to the NSF for some reason.

FDS has it's own file format so .NES won't work. And by the way, the .nes exporter hasn't been updated in a long time so it won't export any expansion chip file correctly.

On pins 3 and 9 on the PC board directly on top of the expansion port, which is why I bought another NES.

The PowerPak is emulating the sound expansions though, isn't it? (I can't imagine it being cost effective otherwise...)

Yes; mapper 20's reserved for the FDS' BIOS ROM cartridge. Technically, the FDS game floppy requires the BIOS ROM in order to boot the floppy, run the program, control I/O access & detect any access errors.

The FDS file format itself, though, isn't part of the iNES format; it's a separate binary disk image format that relies on a BIOS ROM to run (either the file "disksys.rom" or "Famicom Disk System BIOS (J).nes".

As for the PAL/NTSC flags, the FDS was never released outside of the Far East (a region that uses the NTSC standard; namely Japan & Korea). Here's the BIOS ROM's info:

File: Famicom Disk System BIOS (J).nes
CRC: A461436A
SHA-1: B89164B4611E1715D071C8B5FE3C6ADB8E282235
System: NES-NTSC
Board: NROM-256
PRG-ROM: 32k
CHR-ROM: 8k
Solder Pad: H:0 V:1
Battery: No
Dump: Unknown

Tested in Nestopia. I hope this was useful.

An updated version of the .zip from the original developer, for the PP of course.
