I have a link to a compatibility thread just a couple posts above you. According to it both games are compatible. It could be your pen drive, yet you can load your games from it. So I can't say for sure.If you have another drive you could try, it would rule it out. The mod chip usually affects USBAdvance when you start it and gives a black screen. Does your modchip have any boot manager software with it. I would say if it does to disable the macrovision in it if it does.
