Okay This is how to Play Pokemon Black or White on a R4 SDHC or R4i SDHC. (I have tested Black on R4 SDHC).
But before we get started cheek if you have the right R4 it sais [R4 Revolution for DS (NDSL/NDS) www.r4i-sdhc.com] If it sais something like that then it will work.
Things you will need...
Okay so this is what you have to do to run Pokemon Black or White (but i have only tested Black) on your R4DS the original one, I don't think this will work on any clones.
First of all these are the things you will need:
* An R4DS the original one( It sais R4 Revolution for NDS/NDS LITE)...
Cruisn on the Wii is one of my personal examples of that, it's considered one of the worst games of all time, I loved it and completed it several times.
