Download area

The current stable release is v1.45. Older stable releases which might still be useful for some people are v1.40 and v1.35.

Zap distribution sets are made as 'zipchives' - Zip-format archives, compatible with the free InfoZip program (which is available for most operating systems, including RISC OS) and David Pilling's SparkFS. If you don't have either of these, download sparkplug.basic.bin, set its type to BASIC and run it - it self-extracts into a copy of SparkPlug into the current directory, which will also read zip archives.

If you need to report a bug, or want to suggest a new feature, please check the contacts page for the appropriate email address. You should also try to make sure that the bug/feature hasn't already been reported/proposed (the buglist is currently available via the CVS repository, and in recent beta releases).
