was lucky enough to be given a 450d .. started doing google found this an updated 450d from 1.04 to 1.09 (arg when u can find it lol) then 1.10 (had to flash from eos util on pc) and gave your test files ago and it works! OK not much you can do but loads magic lantern menus !! .. I know this camera is so old now and be awesome to have more features but I guess like the most of magic lantern seems to be dead or lack of devs 😔
removed it from my sd card via format option and just stock canon again as lack of being able to do really anything with this so no point leaving it running.
