Thanks very much NiLuJe, I've updated
post #102 to attach the full patch_kobo_3120v010.zip package which includes executables for patch32lsb v0.10 and all the patches from post #1 and #2 updated to use the new keywords.
The patches that can be used for multiple firmware versions have had a comment added to indicate how far back they can be applied.
If you customise the multi-version patches in post #102 then with a bit of luck you will be able to use them in the next firmware version without any further changes.
