The ChameleonMini is a versatile contactless smartcard emulator compliant to NFC. The ChameleonMini was first developed by KAOS. This is NOT the official repo for KAOS's ChameleonMini. For further information see the Getting Started Page
This seems easy enough if you look through the LUFA configuration files in the Chameleon firmware sources. What you need to do is update the strings (and sizes) here and here, and then recompile. If you are talking about the binary naming conventions, that should be in the Makefile?
