Open Source Bootstrap roms

Open source roms are included in the core, adapted from the SameBoy project https://github.com/LIJI32/SameBoy/. These roms have MiSTer-specific enhancements, allowing fast booting and GBA mode to be controlled by the on-screen display.

For maximum compatibility/authenticity you can still place the Gameboy bios/bootroms into the Gameboy folder and load them in the menu with Bootroms->Load GBC/DMG/SGB boot.

For more information see the BootROM README

Palettes

This core supports custom palettes (*.gbp) which should be placed into the Gameboy folder. Some examples are available in the palettes folder.

Custom Borders

This core supports custom borders (*.sgb) which should be placed into the Gameboy folder. Some examples are available in the borders folder.

Autoload

To autoload your favorite game at startup rename it to boot2.rom.

Video output

The Gameboy can disable video output at any time which causes problems with vsync_adjust=2 or analog video during screen transitions. Enabling the Stabilize video option may fix this at the cost of some increased latency.

Savestates

This core provides 4 slots to save and restore the memory state which means you can save at any point in the game. These can be saved to your SDCard or they can reside only in memory for temporary use (OSD Option). Save states can be performed with the Keyboard, a mapped button to a gamepad, or through the OSD.

Keyboard Hotkeys for save states:

• Alt+F1 thru Alt+F4 - save state
• F1 thru F4 - restore state

Gamepad:

• Savestatebutton+Left or Right switches the savestate slot
• Savestatebutton+Start+Down saves to the selected slot
• Savestatebutton+Start+Up loads from the selected slot
