Modified Binary File for Panasonic DMRE95 (and maybe others)

Post by **The Robman** » Wed Jun 14, 2006 6:56 pm

I notice that you quote hex codes in the description of your file. I should probably point out then that the PL bin files are encrypted, so the hex code that you quoted is encrypted also, and the encryption is different for each model of chip that's used (ie, JU, PL, PK, RV).

Here is the excrypted hex code that you were editing...

Code: Select all

0000  80 6f b3 84 61 6f 9b 2e 28 16 1f ad 9d 6f f6 bb
0010  2b de ed 2b ee 48 ec 4c dc 3c e4 44 d4 34 e8 e3
0020  43 3f b4 b0 1e ba 6c 0e 06 16 f6 2a 6d 68 50 6d
0030  f8 2e 0e 50 68 da d6 e6 46 ee ea f8 62 2e 9e af
0040  5f 9e 24 b4 66

And here's the same code un-encrypted...

Code: Select all

0000  44 00 11 54 C9 00 B0 FE E6 9E C2 F8 B8 00 1E 31
0010  F2 BF FB F2 FF 67 F7 77 B7 37 D7 57 97 17 E7 D3
0020  53 43 15 05 BE 2D F5 7E 5E 9E 1E EE F9 E5 85 F9
0030  26 FE 7E 85 E5 AF 9F DF 5F FF EF 26 CD FE BC 01
0040  C1 BC D6 15 DD

If you're going to be editing the binary files by hand, it would probably help to understand the format of the data, which is explained in the following thread...

As for the format of upgrades themselves, here's a quick guide...

Byte Description
1 = byte2 of the protocol id
2 = zeroes, or id of the table entry used for the numeric buttons
3+ = keymap bytes
+ = fixed data
+ = button codes

a) the 1st bit (starting from the left) of the keymap bits indicates where the numeric buttons are present
b) the 2nd bit indicates whether the vlume buttons are present
c) the 3rd bit indicates whether the ch+/- buttons are present
d) the rest of the buttons are represented one button per bit (the order varies by device mode, by remote
e) the 8th bit of each byte is used to indicate whether there are any more keymap bytes

Wow, Thanks.
I got it now.
I would never have been able to do it without your conversion formulas.

I'm going to re-upload it.

Rob,
I tried to update the file, but it just added another file.
The old one is

Can you delete it please to avoid confusion?
Thanks
