This hack is probably the most perpetuated ruse in Amiga history next to the fake Amiga emulator for DOS. The only post-3.1 Kickstart ROM in existence was used in the Walker prototypes and is not publicly available.

The following bytes were changed from the original ROM (checksum A580A2DE):

0000000F: Changed minor revision to 71
0000001A-0000001D: Changed Workbench screen text to "Amiga"
         00000020: Changed Workbench screen text to "RAM"
         00000056: Changed Workbench screen text to "1996"
00000059-0000006D: Changed Workbench screen text to "Amiga Technologies "
         00000087: Changed Workbench screen text to "3.5"
         000000A4: Changed minor revision to 11 (exec.library)
         000000A8: Changed day to 11
         000000AA: Changed month to 1
         000000AD: Changed year to 96
00000248,00000254: Changed to 0x30 for ShapeShifter compatibility
00003740-0000374F: Changed software failure text to "Guru Meditation "
00003755-0000375F: Changed recoverable alert text to "Small Sins "
0000376B-00003777: Changed alert text to "Meditate and use"
         00007B14: Changed to 0x00 (why?)
         00018CF1: Changed initial CON window text to "Amiga OS"
