Can't you use the R4 as a Passme? I think if you boot while holding Select the DS'll boot Slot 2...(I think!)
Got mine from Minionlinestore.. the most gansta of all flashcart sellers, got to Gibraltar no problem and works super with a cheapy microsd I bought on the high street.. Kingston Japan blah blah my rear.
Most peoples troubles with games are likely to be file fragmentation.. i.e. the file isn't stored in a linear fashion and thus the R4 has to stop and reissue commands to the microsd while the DS' interface is trying to burst. I doubt the R4 has any read buffer so to speak. Then they buy a new card and think "magic, because it's japanese it's better than a card produced in exactly the same fab".
Refer to the numerous kingston taiwan vs. japan threads and you will realize that the two cards are actually not the same. In fact, their difference is astounding.
And for those with no problems, just try Castlevania PoR, the most troublesome game of all. My taiwan card was useless trying to run it, but my japan card runs it without a hitch after hours and hours.
I guess that would explain why the 4 that I ordered haven't arrived either. so much for the "ships within 24hrs" that was listed next to the item when I placed my order about a week ago.Ordered mine from Dealextreme 5 days ago for the R4 + microSD combo. Seems like there's a packaging delay. They said they're still waiting for the dealer's package to arrive
