So I got this R4 last April/May I think. So far I can play most of the game I put on it around that time (except for bowser's inside story). It's running Wood R4, not really sure what version it is cause I don't know how to view what's its current version. Also I got this from somebody with everything set, firmware, games, etc. And here are my problems/questions: 1.) Now I'm trying to use the latest Wood R4 version v1.49 I think, and it doesn't seem to work. I just deleted the _rpg folder and the _DS_MENU folder in my SD card and replaced them with the ones from v1.49. But when I tried to turn on my DS I only get a black screen. Did mess something up? Here is the kind of R4 I got: http://lightake.com/detail.do/sku.R4_GOLD_3DS_Revolution_for_N3DS_NDSiLL_NDSi_NDSL_NDS__V1.4.2_-44841 I really want to play some new games. 2.) How do I know what Wood version do I have? 3.) Is Bowser's Inside Story really not working on the Wood Firmware? I might ask a couple of more questions later. Thank you very much.
