I meant they are useless as you can get newer and more compatible revisions! the old EMS carts had teething problems with the 1mb/4mb ram and needed a hardware modification for it to work correctly with games that needed the 4mb expansion... Some places still sell the old version with a comm port (with modification) but i'm not sure if the software is upto date? (most current is V2.02).
Why would anyone choose an old Datel over the newer and much better EMS cart??? My old Datel does not even allow imports to be played!
EDIT: EMS carts with comm port's are pre-2007 and are no longer manufactured so there must be some old stock floating about on the net
... also i cannot find the old comm cart on the EMS website, just the new 2.02 version.
