Feature Request: Full Corona MMC Support with new Xell Implemenation

[knutwurst]

I would like to have full support for 4GB Corona consoles like flashing without weird wiring and flash restore via flash drive.

Describe the solution you'd like

Alex (https://github.com/15432) has two wonderful solutions for writing and reading the 4GB eMMC via the known interface (without SD adapter etc.) and also an Xell implementation that allows you to flash 4GB MMC consoles from Xell Reloaded!

It is actually enough to use the xell.bin from the RGH3 repo (https://github.com/15432/RGH3/blob/main/xell.bin) and maybe just add a reference to the "new" PicoFlasher (https://github.com/15432/PicoFlasher).

For the initial flashing of the ECC/Xell you could use the ready-made binaries (which is what I did) -> https://github.com/15432/RGH3/releases/download/1.0/rgh3_ecc.7z

Currently I have solved everything manually to flash the new Xell, but I would like to see it integrated directly in future updates, as this saves you all the workarounds.

Additional context

For over 12 years, missing features have never been addressed and everyone has just accepted it as a given. But it would be a much nicer and more elegant solution.
