I own a Palm keyboard (Stowaway). I have developed a PERL script to
patch the "keyboard.prc" driver to change the keyboard layout. That
script just change the "map" resource of the PRC file (a big array
describing which symbol is binded to each keyboard physical key)
It's work on PalmIIIx OS3.3 and PalmVx OS3.5 but fails on Palm505 OS4.0.
Is there any mechanism on OS4.0 that prevent a user to patch a PRC file
? (Somethink like : "first of all, before the OS launches an
application, it verify the PRC checksum with a reference value store in
the PRC itself : it could be a way to prevent crackerz to bypass
protection !).
Thank in advance for your feed-back !
Note : I don't have any OS4.x device around to test that behaviour
(someone told me that my software doesn't work on Palm50x, but I didn't
test it myself). I simple test could be to patch any PRC using
"RsrcEdit" and see what happens.
