Picodrive is a Master System, Megadrive/Genesis, Mega CD/Sega CD and 32X emulator running on Maemo-Leste.

(Note: Maemo 5 Picodrive version didn't support 32X emulation)

It works only on Nokia N900 and Motorola Droid 4 at the moment (thanks to their physical keyboards).

The emulator uses the generic GTK UI: This version of Picodrive is based on a well working raspberry version and not the old maemo one.

  • Megadrive games are playable, with sound and input, running at 30 fps on N900 with frameskip=1.

Without frameskip and sound, games run at 60 fps with default CPU frequencies.


  • 32X games are only playable without sound on N900 and run at around 40-50 fps. Some games work better with frameskip=1.


Default configuration is already optimised for Megadrive/Genesis games (with sound and 30 fps). Like other emulators hildon compositing must be deactivated while playing, using Ctl+Shift+N.


Keymapping and all other parameters can be modified directly in the user config file available in /home/user/.picodrive/config2.cfg


WARNING: on N900 in the GUI, 'enter menu' is associated to 'escape' key. 'back' is associated to 'e' key (hardcoded).

Almost all configuration parameters are available from the GUI.

Aladdin, , Behind Oasis, Desert Strike, Psycho Pinball, Phantasy Star 4, Sonic 2, Sonic 3, Street Fighter II CE, Strider, James Pond, Landstalker, Monster World, Quack Shot, Road Rash, Street Of Rage 2.

Tips

If (for some reason) the GUI is not working, it is possible to directly launch a game from command line:

/usr/games/picodrive/picodrive /game_dir/your_game.zip

Default keymap is visible in /home/user/.picodrive/config2.cfg

On N900, it is recommended to activate boost mode (720MHz or 805MHz) while playing 32X games.

As root:

echo 1 > /sys/devices/system/cpu/cpufreq/boost

echo 720000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

TODO

  • Implement sane default keys for the devices
  • Try to implement Maemo 5 -touch- UI
  • Find a way to get a proper fullscreen mode
