I would like to confirm that Pokemon White 2 works perfectly on R4i Gold Plus running RetroGameFans latest firmware. I just patched the ROM with the ds-scene tool and played it. Have not tried to trim the ROM yet but I assume it'll work still.
EDIT: I have tried Pokemon White 2 and Black 2 clean and trimmed, and both work flawlessly. I experience no crashing of any kind, no noticeable or crippling lag, and I can gain experience.
