Introduction
TODO this is a work in progress, please help fill it in.
Starting with version 1.1, CHDK uses loadable binary modules (similar to .dll or .so files on other platforms). This reduces memory requirements and allows platform independent binaries to be made.
Development thread http://chdk.setepontos.com/index.php?topic=847.0
Thanks to tsvstar for the initial implementation of the module system.
For end users
In 1.1 and later, a minimal install of CHDK must include the modules as well as well as the CHDK core (DISKBOOT.BIN and/or PS.FI2, PS.FIR). Modules reside in CHDK/MODULES and have a .flt extension.
On multi-partition cards, the modules must be installed in the main (large) partition that the camera sees, not the small boot partition with diskboot.
For developers
