Thanks J-F ! I can confirm the patch works on the HP-15C Limited Edition

That's great news and you beat me to it!
Can you give details of the method you used to flash?

I assume you applied the patch bytes directly to the posted final beta rom using a hex editor.

Did you follow the method described here:

An original (or patched) rom binary file into address 4800-77FF leaving the nut emulator in situ using Mysamba?

Edit: ah, just looked at HP15C- 04-15-11 LATEST.bin in a hex editor and can see the rom is unencrypted and starts at address hex100 so can be directly patched
