Gameboy emulator for Sailfish OS

Put your *.gb roms to "/home/nemo/Documents/jboy_roms". The folder will be also created on first launch.
Some *.gbc roms can also be played with jBoy. Just rename them to *.gb and they can be started.

Features:
- Running most Gameboy roms
- Gamepad in theme colors or original color
- Option for emulation speed (5 Steps)
- Show FPS during emulation
- Option for original screen color or greyscale
- Logging on file (primary for bugfixing) to /home/nemo/Documents/jboy_log.txt
- Supporting MBC1, 2, 3 (with RTC) and 5
- Supporting up to 256 rombanks and 16 rambanks
- Original RAM saving when cart is using a battery (Creating *.sav file for *.gb file)
- Savefiles are (except RTC-Roms) compatible with other emulators
- Gameshark cheatcodes (Up to 25 per rom)
- Scale screen up to three times (Default size can also be set)
- Screenshots (saved in original resolution in "/home/nemo/Pictures/jboy_screenshots/%Timestamp%.png")
- Debugger (primary for my own bugfixing)
- Savestates (inclusive quicksave and -load)
- Sound support
- Link-Cable emulation (in this version either online or local via another instance of the jBoy Color application)
- Sailjail Sandboxing is deactivated in this version (due to problems with the local linking-cable emulation)

 

Do not run any software you don't own with jBoy.
