No way to port it to Mac, I simply do have neither skills nor compilers...
I decided not to integrate romident functions because this would lead to a never ending update battle... But ROM-Wizard has an integrated "Ask Google" tool, just right-click on your ROM and choose "Google Suche..."
Then the SHA-String will be automatically forwarded to a Google search. Try it out. If Google doesn't find anything, your ROM is either unknown or corrupt.
