Will a romeo mod need to be applied if you play backup games (such as with ESR) on a version 9 PS2? I thought that it was only needed if you modded your console or changed the laser but some people have told me that just playing any non-original media will kill the laser. Could anyone clarify this? My friend has offered to trade me his V7 39003 or V5 30003 R for my V9 50003. Should I go ahead with the trade, and if so, which PS2 should I ask for?
