v0.9 (upcoming release)

Note: These are the release notes for the nightly build, which is a release not publicly released, but under development. The release notes will be updated periodically as we keep improving the Operator software.


As always, we'd like to thank the community for submitting requests to our support team. This release focuses on controllers and keyboard controls. Adding more support for an additional 180 types of controllers out of the box, and improving the rebinding systems.


Operator software:

  • Autosaving support: Now the game is able to save directly to the cartridge. There's no longer need for the Emulator to ask the user to write the save.
  • Automatic save backups: Now the emulator makes backups of your saves also before writing to the cartridge. So that, in the situation in which the emulator, for whatever reason crashes, or the device disconnects. You can manually upload it back, without losing your progress.
    The software makes backups in the following situations:
    • When reading save data before launching the game
    • When writing save data while playing
    • When reading/writing save data from the Data tabs
  • Emulator Settings:
    • Fast-forward speed multiplier (from 0.25x to 5.0x)
    • Force Game Boy Model
    • Customizable color palettes
    • Hardware preset Game Boy palettes
    • Super Game Boy Border support
    • Color Correction (adjusting output colors to match real GBA/GBC hardware)
    • Interframe blending
    • Audio Low Pass filter configuration (with levels)
    • Allow Opposing Directional Input
    • Solar sensor levels (not from the hardware, just simulated)
    • Frameskipping with thresholds and intervals
    • Idle loop removals
  • Rumble support for games and controllers that support it (e.g. Pokemon Pinball)
  • Future support: added support for our upcoming devices, the Operator software now detects the type of device inserted and changes the emulator being used (now GB/GBC/GBA and SNES)
  • Gamepad rebinding: fixed an issue when rebinding a controller that has analog buttons would trigger the binding sequence for other buttons as well, making it impossible to rebind your controller. Tested with previously not working 8BitDo SN30 (model 80BA)
  • Gamepad support: updated SDL version fixing a bunch of controllers.
  • Save data: added the feature to preserve the current RTC values on the save file that is being downloaded from your cartridge.
  • Playing: added RTC support for GB/GBC in the emulator.
  • Major security and stability improvements, bringing the application closer to a stable release. This is where most of the work was done for this release.
  • Ability to switch from GB Operator to SN Operator (not yet publicly available).


GB Operator:

  • Faster bootleg rewriting for GBA: 4 times faster chip erasing implemented for most bootlegs
  • Added RTC support for GBA* 
  • Added support for flashcarts/bootlegs which require flashing commands on Bank 1.
  • Added support for flashcarts from Ferrante Crafts (32KB, 64KB and 512KB).


Game Save Type Auto-detection Updates:

There were reports of the cartridges below experiencing issues with the 'Upload Save' feature. With this release, users are now able to download/upload saves seamlessly.

  • NES Classics - Castlevania


Preservation efforts

Due to the amount different archivists that submit video game data to databases, there are instances in which the archives they create don't have the most accurate data. We use these databases in order to provide you integrity checks, however sometimes our community discovers wrong submissions.

Here we list the games which had wrong checksums and have now been corrected thanks to community contributions.

  • Minna no Soft Series - Tetris Advance (added both an additional revision of the game)
  • NES Classics - Castlevania (added an additional checksum to the database)
  • Three-in-One Pack: Risk + Battleship + Clue (improved game information)
  • NES Classics (added in-game save reading/writing)
  • Ougon no Taiyou: Ushinawareshi Toki (added support for save data read/write)
  • Sky Dancers: They Magically Fly! (improved game description)
  • Tactics Ogre - The Knight of Lodis (USA) (added support for save data read/write)
  • Knights' Kingdom (added game information)
  • Mahoujin Guruguru (added game information)
  • Crash & Spyro Superpack: Spyro: Season of Ice + Crash Bandicoot (added game information)
  • Monsters, Inc. (improved game information)
  • 2 Games in One!: Gauntlet + Rampart (improved game information)
  • Ranma 1-2 (added game information)
  • Barbie Groovy Games (added game information)
  • Konjiki no Gashbell!! Yuujou no Zakeru: Dream Tag Tournament (added game information)
  • 2 Games in 1: Quad Desert Fury + Monster Trucks (added game information)
  • Double Game!: Quad Desert Fury & Monster Trucks (added game information)
  • 3 Game Pack!: Mouse Trap + Simon + Operation (improved game information)

Note: mGBA does not seem to have yet the ability to load RTC data for GBA via the save file or other mechanism, most likely will be implemented in a future update.
