Well, i would like to understand why....I'm getting another Slot4 this week to have more test and compare.I dont know why is that. Maybe those carts are making some kind of read/writes to some zones that the cart also has and are related to protection. In any case, I hope you are OK playing it with League Bowling.
=> I hope my multimvs is healthy (I'm not the only 4 slot owner and i would be the only one to report???).
let's see....Anyway thanks for your reactive support. (my other purchase CPS2 multi is great and was easier to setup )
