SD1000 (IXUS70) 1.01A works with CHDK for version 1.01B

Hi all,

tried the search function on "1.01A", IXUS70 and SD1000, but so far no good.

Is there a way to get CHDK for the IXUS70/SD1000 with 1.01A?
I found my own firmware on the SD1000 - CHDK Wiki page, but i'm not SO technical that i dare to hack it myself.

Can't find a possibilty to upgrade my firmware on the internet either.

Any help?

It was a bit of a scary thing to do for the first time but i tried the Allbest update for the IXUS70 on 1.01B, and it seems to work.
Is that just me being lucky or is that supposed to work?

I've compared two dumps (1.01a & 1.01b). It seems they differ only in some data. All referenced addresses are the same.

What a coincidence, I tried the same two days ago. It seems to work indeed, though I didn't tested all features the firmware has to offer yet.
