ugBASIC is an isomorphic and open source language, fully documented and designed to develop portable programs, without sacrificing efficiency. With a single source it is therefore possible to create games for numerous 8 bit platforms.

You can download the official ugBASIC compiler (ugbc), which directly converts a program written in ugBASIC into the assembly equivalent for the given CPU / computer. The compiler is free, open source and licensed under the Apache 2.0 license. You can download or recompile the latest version from the GitHub repository.
On this video, you have the example of a real-time animation of 4 fairly large sprites on Thomson MO6. Sprites can also move in a full background setting. This new language will allow for hyper-fast game development on all 8-bit consoles and computers.
Full and complete support for console hardware features on ColecoVision, SEGA SC-3000 and SEGA SG-1000. Automatic graphic conversion from modern graphical formats included.
Each target can have a dedicated optimizer, which allows to achieve very interesting
results while leaving the BASIC code fully readable.
Here we see the peephole
optimizer for Motorola 6809 in action.
With ugBASIC is simple to write multitasking programs using parallel programming, available "out of the box". In systems with severe memory constraints such as computers based on 8 bit processors, a mechanism based on protothreads has been implemented.
Developing for multiple platforms requires little effort, because the source does not have to be adapted. With a single source code you can get games and programs for multiple computers, even very different from each other.
Compile your ugBASIC sources efficiently and effectively for multiple retrocomputers: ugBASIC IDE makes it easier to download and install the various software required for one or more retrocomputers, all just one "click away".
At the moment there are two manuals available: the user manual, with which you can start developing using this language, and the reference manual, useful for those wishing to modify and/or to extend the language.
The current version (1.13) introduces support for Radio Shack TRS-80 Color Computer.

Happy birthday ugBASIC! Today (25/04) we celebrate one
year since the first commit, and with this milestone in
mind let's take a look at some of the results obtained by
the development team.
From a qualitative point of view, the system
supports as many as 14 heterogeneous systems,
ranging from ATARI to Olivetti Prodest, passing through MSX and,
obviously, Commodore computers.
From a quantitative point of view, ugBASIC is composed of over
137,000 lines of C code and over 36,000 lines of assembly code
(MOS 6502, Zilog Z80 and Motorola 6809), where the lexer and the
parser occupy 6,408 lines!
Following the sizing indicated by the "COCOMO model", to redevelop
ugBASIC from scratch it would take 55 man-months or, if you like,
two and a half years of development. Alternatively, having 22 developers,
it would be done in a year.
