For the record, I did try searching around some forums and some wikis for an answer, but most of the topics I looked at in my search usually just asked if the 3-in-1 was a good slot-2 to use with it. Anyway, I have been able to use it to emulate GBA games using that app from Rudolph. But is that most I can do with my 3-in-1? My CycloDS firmware recognizes it as having rumble (which it should), and I can enable it, but when I trial-tested the rumble with Metroid Pinball, the game itself didn't recognize that there was a rumble pack in there. From a little bit of reading, I think I'm supposed to soft-reset something to get the rumble and the RAM working? One of the topics says that GBA emulation does not natively allow for a soft-reset back to the DS software, because that's just how it works out. And I've seen some wikis refer to a file called "SoftRest.CEVO" for soft resetting. Where do I put that file, if that is what I'm supposed to be using to activate the rumble? Any tips on what to do to get the most out of my 3-in-1, using the CycloDS?
