Very good work, I just updated to firmware i and it works for me!
Hey, I noticed there's a PS.fi2 file included. So I tried loading CHDK via firmware updated and that worked too (am I the first to notice?)! So glad I can use my SDHC card with CHDK now.
Thank you soooo much!
Oh, for those asking about ISO override, other versions have the same issue (or, at least d).
