Two versions of GCBASIC are available. The older version, which is easier to install and has all of the correct translations in it, or the newer version, which has less bugs and more features, but doesn't have up to date translations or an installer. For AVR support, you will need the newer version.
Files marked in bold are the recommended downloads.
| File | Version | Description |
| GCBASIC_Installer_0930.exe | 24/2/2007 | Installer for GCBASIC. Includes gputils, which this version requires to assemble programs. Note: The version of gputils included in this file is now outdated |
| GCBASIC_Minimal_0930.exe | 24/2/2007 | Installer for GCBASIC. Doesn't include gputils - use if you already have MPASM or gputils, or wish to download gputils separately. Use this if you are going to install the newer version, but need the Italian or Turkish translations. |
| GCBASIC_zip_0930.zip | 24/2/2007 | Archive containing only GCBASIC. Extract to a folder to run. |
| gcbasic.zip | 9/9/2009 | Archive containing the latest version of GCBASIC. You
can use this by itself, or extract it over an existing installation of
GCBASIC to update it. If this is the first time you have used the gcbasic.zip version, you will also need to save gcbasic.ini to your GCBASIC folder. This settings file is not included in any updates - including it could result in someone's customised settings being removed. |
| gcbasic-nochipdata.zip | 9/9/2009 | Archive containing the latest version of GCBASIC, but without any chip data files. Use this as an update for your existing copy of GCBASIC if your existing version is newer than 17/5/2009. |
A file listing the changes made in each newer build is available here.
