Famicom Disk System

[Upstream illustration: fds_header]

The Family Computer Disk System a.k.a. Famicom Disk System was released in Japan in 1986. It is an add-on to the Famicom and used floppy disks.

Emulators: lr-nestopia, lr-fceumm, lr-fbneo

ROMS

Accepted File Extensions: .7z .fds .nes .zip

Place your FDS Roms in

/home/pi/RetroPie/roms/fds

NOTE: lr-fbneo expects the game roms to be in .zip/.7z archives named in a similar fashion to arcade romsets, so the filenames of the roms is important. Use a romset validation/building program like Clrmamepro or RomCenter to have the correct filenames, with the FBNeo FDS DAT file file and a No-Intro NES ROM collection to get the correct ROMset.

BIOS

FDS games require the disksys.rom bios file. Place the BIOS in:

• /home/pi/RetroPie/BIOS for lr-fceumm and lr-nestopia
• /home/pi/RetroPie/BIOS for lr-fneo, zipped in a file named fdsbios.zip

Controls

Both emulators utilise RetroArch configurations.

Side Note: In order to "switch to side B" of a ROM most controllers have this set to a default of the upper right bumper or right trigger button

Side Note: Games that display Ｂメンヲセットシテクダサ are asking for the disk to be flipped to side B in order to continue. It is common for a game to display a title screen that asks for side B before the game can start.

Add custom retroarch controls to the retroarch.cfg file in

/opt/retropie/configs/fds/retroarch.cfg

For more information on custom RetroArch controls see: RetroArch Configuration
