What's News Get Started IDE SANDBOX Games

WHAT IS ugBASIC?

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.

Download the compiler

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.

* = available only for Microsoft Windows 7/8/10/11

Documentation and manuals

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.

What's news?

 

 

The current version adds support for the TRS-80 Color Computer 3 (coco3) and is able to generate disk images for ATARI, MSX and Commodore VIC-20. Further optimizations have been introduced in the generated code, in particular for CPU Z80. Several commands have been added, and there is also better compatibility with 1980s BASIC syntax. Moreover, it can load and save data to mass storage.

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.

FALLING BALLS (10 liner)

This game is a multitasking arcade game for one player. The player must drop balls into the baskets at the bottom of the screen, in the shortest possible path. The longer the ball travels across the screen, the fewer points he/she accumulates. This game joins the "BASIC10Liner" competition 2024

PICK THE STAR (10 liner)

This game is a multitasking arcade game for one player. The player must pick mostly the stars that descend from the top of the screen, because they give to the player the higher score. This game joins the "BASIC10Liner" competition 2023

TIC-TAC-TOE (10 liner)

This game is a traditional paper-and-pencil game for two players who take turns marking the spaces in a three-by-three grid with X or O. This game joins the "BASIC10Liner" competition 2023
