Patch firmware version string to indicate patched firmware. #16

Closed rct closed 8 years ago

rct commented 8 years ago

Patch the firmware version string (bytes?) that gets display from the Radio Info menu to differentiate from stock unmodified firmware. A one byte difference might help avoid some confusion.

Note Radios that are configured to display text lines on start up from the codeplug won't show the PoC || GTFO logo from the patched firmware.

The easiest place to patch seems to be the Firmware Ver. string at 0x080d14d8 or the Radio Info string at 0x080d1d68.

Either can be seen in Menu/Utilities/RadioInfo/Versions, but "Radio Info" is used in menu different locations, so it is less appropriate to patch.
