I am quite enjoy and learning a lot using CHDK with my S3 and SX10 (not much on SD500) for several days now. Few thoughts and questions yet don't know which to start, just post whenever question rises.
Perhaps at least for starting;
101b-0.9.9-869 full for SD500 / 1G SD
100a-0.9.9-966 full for S3 / 8G SDHC
101b-0.9.9-966 full for SX10 / 16G SDHC
Somehow, I can not install 102b or 103a onto any card for SX10. Either the camera "freeze-up" or not booting. Everything is fine after switched back to 101b. So the question now is : Am I using the updated CHDK for the SX10?
Thanks
