The person that probably got the email didn't have the authority to say anything, so passed it on up the chain until someone nearer the top said to just ignore the email. If you want to convert the game I'd say just do it - I can't see them busting anyone for converting the game to a "dead" system.
Your comment "Guess nobody was interested after all" - are you referring to Microids or the EAB guys? If you mean the EAB guys, the problem is more likely that none of us know the game or have played it so can't really comment. If it's aimed at Microids, well I could have told you they'd ignore you. Most companies completely ignore requests/permission for things
