Firmware hacks... opinions and experiences?

Digital cameras are, of course, just portable computers with onboard image sensors. Over the years, some truly inspired programs have been run on them - I had a Kodak DC290 which, I kid you not, I could play "Doom" on.

However, computers can be hacked. An enterprising fellow in Russia has developed a hack for the EOS 300D (aka the Digital Rebel) which activates many of the features which the hardware suports but the camera will not allow you to engage. (Most of these are features it has in common with the EOS 10D, which shares a common codebase with it. They have the same CPU.)

Among them are:

1) Mirror lockup.
2) Flash Exposure Compensation.
3) ISO 3200 (from factory firmware high of 1600)
4) A modification that allows you to use the command wheel to change resolution on the fly. (You don't have to use the menu system.)
5) The ability to change the size/quality setting for the JPEG which is embedded in all RAW images.

This is a mighty tempting free upgrade that puts the 300D most of the way to a 10D: the remaining features (bigger buffer and metal body) are hardware-dependent. Anybody tried it? Anybody have experience with similar sorts of hacking?

No camera hacking problems, but I do have problems with a computer hacker that I don't seem to be able to get rid of. [img]/ubbthreads/images/graemlins/frown.gif[/img]

I will not post a link to the hack so Rolando doesn't get a nasty letter from Canon. Anybody who wants it may PM me and I will send it to you.

Yes, I know several people who have done it. So far the only negative consequence is a failure of the SET button which honestly sounds like a mechanical failure, not a software glitch. Several people have also reverted to factory firmware with no problems for whatever reason. Technically Canon won't service a camera with hacked firmware but people have reported sending them in for service with the hack in place and getting them back the same way.

Hundreds if not thousands of people have implemented various versions of the hack and I have seen *no* reliable reports of camera failure. A few people have had problems with corrupted firmware files (probably due to a bad download) but after a restore and reinstall with fresh copies they were good to go. It certainly seems worth a shot.

Wow....that is pretty darn cool of some hack! Does anyone know if there is some hack that can speed up my 10D bodies?? ...like the frame rate....or if I can play "DOOM" on mine too?? [img]/ubbthreads/images/graemlins/cool.gif[/img]

Unfortunately, you need DigitaOS to run the MAME emulator that I used. Since the chip in the 10D and the 300D can run x86 EXE's, it's possible, but I doubt anybody will do it. Unlike DigitaOS, the proprietary OS's that Canon uses are not available to developers to monkey with. Sorry. [img]/ubbthreads/images/graemlins/frown.gif[/img]

As far as the frame rate, no on that one too - it's entirely dependent on the size and speed of the buffer RAM, which is not changeable unless you're an electrical engineer with nerves of steel and a lot of free time. That's the one thing that no hack will ever raise the DR to the level of the 10D on.

Gosh, I'm just full of bad news. Sorry again.

How does anyone download anything to their 300D?

Another question: I saw the hack site for the 300D, and I still don't understand how to change any functions (ex: mirror lockup). Can anyone explain this to me?
