UGBasic is an open-source, isomorphic BASIC compiler designed to create portable and efficient programs for a wide range of 8-bit retro-computers.
It allows developers to write a single source code that can be compiled for multiple vintage platforms—including Commodore, Atari, Sinclair, Tandy, and more—without sacrificing performance. ugBASIC supports advanced features like graphics rendering, sprite manipulation, multitasking via protothreads, memory bank management, and inline assembly. Its integrated IDE streamlines development, and the language includes modern conveniences such as conditional compilation, structured types, and support for various CPUs like the MOS 6502, Zilog Z80, and Motorola 6809. With ugBASIC, users can rapidly build games and applications that leverage the unique capabilities of classic hardware
