Thanks Otaku! Your efforts are _greatly_ appreciated.
Regarding from your website:

I have had a preliminary shuftie : I might try knocking together a new firmware image if I can find someone (brave|stupid|willing) enough to install it .. :)
Count me in as (brave && stupid && willing) :)

Oh, also, FYI..
The unlock keys are stored in ata_hdd.dll
The one from the firmware image I unpacked appears to have 2
B2 BA B3 BC B0 DF AC BE B1 BB BE DF B1 AD D2 CD C9 CE AA B2 DF B1 9E 89 96 DF AA 8C 9A 8D DF DF
B2 BA B3 BC B0 DF AC BE B1 BB BE DF B1 AD D2 CD C9 CE AA B2 DF B1 9E 89 96 DF B2 9E 8C 8B 9A 8D
One is a User key, the other is a Master key.

For the 261EM version (Outlander 07) I can also test an image. I don't think there is something to screw as long as I use another disk. So, count on me :)

Heh..
I _believe_ it should be ok... I'll see if there is a fairly low level way of backing up an existing working system before we try screwing around with it .. :)

Well I took the plunge and started screwing around with it :)
Here's my results.
I downloaded the modified image you created for the dvd-in-motion hack and pulled the hard drive from the MMCS and updated the loading.kwi file with yours and put the drive back in.
When I turned the ignition key on, the MMCS booted as usual. Turns out you have to disconnect power from the MMCS for a few minutes to get it to do a "Cold" boot. I assume a cold boot is the only time the bootloader code is invoked.
Anyway, the bootloader came up with the message "Program version-up in progress." with a progress bar that filled up within about a second. Once the progress bar filled up, the screen went blank and nothing would happen. Sigh :( Each time I turned the ignition key off and on, it'd just do the same thing.
Since I figured this modified firmware wasn't going to work, I decided to do some experimenting with the bootloader.
I removed the hard drive from the unit and turned the key back on. I got a message "Insert a program disk."
I already had a CD burned with the mitsubishi's original "loading.kwi" file on it, so I stuck it in the drive and got a message "Now checking the disk." After a few moments, it came back with this message "Program writing error. Turn the engine key off to retry." Oh well.
After that, I put the original loading.kwi back onto the hard drive, it did the 'program update' just as it had been before, then immediately after got a message "Checking screen data.", then shortly after a message "Screen data check has been completed. Restarting"
And all was back to normal.
Sounds to me like we are _extremely_ close to being able to modify the OS on this thing! Stay tuned!
