Why GB BASIC?
GB BASIC is programmable in a brand new BASIC dialect. The integrated assets editors are intuitive to use. You can generate real ROMs and play on any GB emulator or hardware.
- GB BASIC compiles fast
- GB BASIC generates ROMs for various mappers, devices and emulators
Features
- Programmable in BASIC, an easy to learn and fun to use programming language
- Easy to use API for graphics, input, audio, and other facilities
- Built-in libraries for scene, actor, controllers, GUI
- Built-in libraries for collision detection, persistence, RTC, etc.
- Extension feature including mouse & touch, shell command, debugging, etc.
- Handy tools for editing tiles, map, scene, actor, font, sound, etc.
- Project can be exported into real ROM
- Dozens of example projects
