furNES

an NES sound driver for Furnace (pun intended)

THIS SOUND DRIVER IS CURRENTLY A WIP

A Furnace sound driver that's easy-ish to use? Yes, this is real, but you can't just drop in any .fur file with the NES chip enabled. You have to follow these rules/guidelines for your .fur file to be furNES-compatible.

• You have to have Python and the CC65 toolchain installed

• You have to set the pitch linearity option to "None". You can do this by going to window -> song -> compatability flags -> Pitch/Playback -> Pitch linearity and then setting the option to "None".

• This only supports 2A03, FDS and VRC7 (which can be enabled through a flag in the driver source). Also this only supports DPCM samples, so that means that there will be no 7-bit PCM samples :/

• The driver only supports arpeggio, volume and duty/waveform macros in each instrument and it DOESN'T support LFO and ADSR macros nor delay and step length

• The furNES driver only supports these effects:

  • 00xx: arpeggio
  • 01xx: pitch slide up
  • 02xx: pitch slide down
  • 03xx: portamento
  • 04xx: vibrato
  • 09xx: set speed 1
  • 0Dxx: jump to next pattern
  • 0Fxx: set speed 2
  • 0Axx: volume slide
  • 10xx: set patch/waveform (for VRC7 and FDS)
  • 11xx: write to delta counter
  • 12xx: set duty cycle/noise mode
  • E1xx: note slide up
  • E2xx: note slide down
  • E5xx: note fine-pitch
  • ECxx: note cut
  • EDxx: note delay

when you've finished / want to test out this driver:

• open the terminal/command prompt to the furNES directory
• run convert.sh your_fur_file.fur or convert.bat file.fur (depending on your OS)
• in the furNES/nsf directory you'll hopefully see a file called furNES-test.nsf
  • that's your .nsf music file that you can play on any hardware or software NSF player!

Hopefully you'll have fun with my driver :D
