DMCA arcade and console game exception

BoingBoing posted this about six new exemptions to the digital millennium copyright act. In particular, note this one (the paragraph below is the EFF's summary):

2. Computer programs and video games distributed in formats that have become obsolete and that require the original media or hardware as a condition of access, when circumvention is accomplished for the purpose of preservation or archival reproduction of published digital works by a library or archive. A format shall be considered obsolete if the machine or system necessary to render perceptible a work stored in that format is no longer manufactured or is no longer reasonably available in the commercial marketplace.

Hmm...

I wonder what that implies for arcade or console titles that are for obsolete HW, but for which emulated or re-written versions are still in distribution?
