gba

It's a gba emulator. Things are mostly working.

Notable stuff still TODO:

• Optimization
• GB sound (non-DMA/PCM sound)
• Mosaic effect
• Better CPU/memory cycle accuracy
• Customizable controls

Building

• Install SDL and cmake, and optionally Capstone for disassembly output.
• cd build && ./build.sh
• Build tested on Linux and MacOS. Windows unsupported at this time.

Running

• ./gba rom.gba

Flags

• Use -s to skip the bios
• Use -b bios_file.bin to load an alternate bios
• Use -S X to set the scaling factor for the screen to a provided integer. Default 4.
• Use -v to enable verbose logging. Repeat up to 3 times.
• Use -d for debug mode. Currently does nothing.
