I, too am seeing this RTC issue with Prism. Still happening on 1.04 FW4. The RTC functionality of this card is a big incentive for Prism players, so it would be great if we could get to the bottom of it.
Is there any good way to debug this from our end besides trying different emulators? This quirk appears to be unique only to Prism + EZ Flash Jr.
happens on other flashcarts as well like the Everdrive GB X7
