I tried ... I press the playbutton and i pressed the FUNC button I waited 2 ... 3 ... 4 minutes I put the sd in the notebook and nothing
Make sure the dumper script is saved as plan text (ANSI in notepad) on the card as EXTEND.M (not EXTEND.M.TXT or something like that)
I already had a Canon SX 50hs with CHDK ..
If you already have CHDK on another camera, you can also use that to make a script disk, with the attached lua file. You need turn on "Enable Lua Native Calls" in the CHDK miscellaneous menu.
After you prepare the card in your SX50, be sure to unlock it so your SX60 doesn't try to boot SX50 CHDK
