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.
This is an example of vector graphics render with ugBASIC. The characteristics of the language are such as to allow fast execution of the same BASIC source on various home computers and consoles.
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 adds preliminary support for inline assembly, software for map tiling, system calls, the floating point data type, for the Commodore 128 target with the Zilog Z80 processor and for graphics blitting operations.
Further optimizations have been introduced in the generated code, in particular for the Olivetti Prodest PC128 home computers, which is now able to handle banking at the single frame level instead of the whole image, and for the COCO TRS-80 computer,
which can now make use of almost all available memory, including that under the ROM banks.

Happy birthday ugBASIC! Today (24/04) we celebrate two
years 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 26 heterogeneous systems,
ranging from ATARI to Olivetti Prodest, passing through MSX, TRS-80 and,
obviously, Commodore computers. A dedicated page takes into account the
actual list of supported targets.
From a quantitative point of view, ugBASIC is composed of over
156,000 lines of C code and about 43,000 lines of assembly code
(MOS 6502, Zilog Z80 and Motorola 6809), where the lexer and the
parser occupy 7,559 lines!

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.

ugBASIC v1.14: A New Era for Commodore 64 Programming
The Commodore 64 is one of the most popular home computers of all time, and it is still enjoyed by many people today. However, the original BASIC interpreter that came with the C64 was not very powerful or versatile. This is where ugBASIC comes in.
ugBASIC
ugBASIC is a modern, open-source, active (as of March 2023) BASIC cross-compiler able to generate machine code for multiple computers built around the Motorola 6809, Zilog Z80 and MOS 6502 8-bit processors which were popular both in the USA and European markets in the 1980s and 1990s.
ugBASIC
If there's one language that just can't be killed, it's BASIC. Not that there aren't others, but BASIC has a very special status.
