GameBuilder BASIC (GB BASIC) is a retro Fantasy Console that generates ROMs compatible with the popular handheld game console. It has everything ready-to-use for writting code, making assets, compiling projects, running with the built-in emulator, exporting to runnable ROM, etc. 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. Programming Paradigms Imperative paradigm Non-structured programming Concurrent processing approach Declarative paradigm Data driven approach 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 Specs CPU: 4.19MHz/8.38MHz for classic/colored respectively Threads: up to 16 concurrent execution contexts Display: 160x144px Code: BASIC, supports multiple source pages Gamepad: 8 buttons (D-Pad + A/B + Select/Start) Mouse and touch: supported by extension Tiles: up to 256 units per page Map: up to 255 tiles in one dimension per page; two layers (graphics, attributes) Sprite: supports 8x8 and 8x16 sprites Scene: up to 255 tiles in one dimension per page; four layers (map, attributes, properties, actors) Actor: up to 8x8 tiles per frame; up to 1024 frames per page Font: supports TrueType (.ttf) and bitmap-based (.png .jpg .bmp .tga); up to 16px; 1bpp or 2bpp Audio: 4 channels; supports importing from JSON, VGM, WAV, FxHammer Palette: 2bit (4 colors) per tile, palette of map and actor is configurable for colored device GUI: supports label, progress bar, menu, etc. Persistence: supported RTC: supported Serial port: supported
