You set the "boot flag" on your cam. It will now check for a bootable card each time battery hatch is closed and each time the cam is powered up from powersave. If you insert an incompatible card (very, very old EyeFi cards) cam will get stuck. If a bootable card is found it will check for autoexec.bin. If no autoexec.bin is found cam will get stuck. Just don't use bootable cards without autoexec.bin.
You haven't flashed a custom ROM to your card. Your firmware wasn't replaced. ML runs from card, not from NVRAM.

And you may consider not going somewhere without checking the consequences of your actions. Maybe consider asking before doing something if you're unable to check the consequences.
Just saying ...

So, which are the functions avaiable on the fishy build or it's just a visible GUI with no features for the april fool's day?

Thanks i want to test it too but i have no time right now, thanks @safwanck for your post.

Thanks for the info. I personally test everything myself, ie why tested the fishy build without looking for more details.

Are you willing to donate few bucks ?

Yes.  send me/reply with a link?

Do you happen to know if any of the devs have an M50 and if that's the major block to further development?

Hi,

Could you please provide me raw samples in continuous mode (both raw and c-raw) ?
So that I can check it is 12bits or not ?
It should be stored in CMP1, offset 32.

Kind regards

I don't think devs share your problem. See nanomad's reply https://www.magiclantern.fm/forum/index.php?topic=3096.msg14579#msg14579

Hi,

I'm documenting the CR3 format here : https://github.com/lclevy/canon_cr3
Any CR3 capable model with continuous model can help, please.

12bits in continuous mode has been discussed in this thread, that's why I'm asking here.

Kind regards

Hi,
It seems continuous mode in M50 produces 14 bits, sorry.
But G5 X Mark II and G7 X Mark III do produce 'raw burst', with several pictures in one CR3.
https://www.dpreview.com/reviews/canon-powershot-g5-x-mark-ii-review/5

"Another thing to note - the camera saves all the image in a sort of 'wrapper,' with the 'CR3' suffix. To open them on a desktop machine, you'll need to use Canon's Digital Photo Professional software. You can also extract and process individual files from the camera and save them out as JPEGs that way if you prefer."

Kind regards
Laurent

Sure?
I also looked at the RAW data of the M50 some time ago. The data in continuous mode looked like the histograms of the previous posts. There is definitely a lack of information. Maybe the result will only be shifted to 14bit.

Canon has released a firmware update for the recent PowerShot G7X III. Can someone take a look at the FIR and tell whether the current decoder/decrypter can still cope with it?

It appears to use the same file format as EOS R/RP and 250D. That means, I'm unable to look inside without physical access to the camera (such as the UART interface).

Thanks. That means, reversing the new format will be mandatory before any serious development effort on these new (and future) models.

Does that say that it is an EOS firmware?

Would a firmware dump in the camera bring more?

The FIR file format is the one used by EOS firmware. Whatever is inside, I don't know, but I'd expect something similar to the other EOS/PowerShot "hybrids".

Not exactly a priority for me right now - but once (if ever?) I'll be able to handle the already-started DIGIC 6/7/8 ports, including M50, I'll also look into newer models. The only problem is time - if you solve that for me, I can handle the rest :)
