Pokemon Black and White on R4 III Upgrade chip

It works for old R4 card with YSmenu to play Pokemon B/W

BUT it doesnot work when playing Eigokoro.nds and New Fire Emblem.nds

it reports rom load error -5

So if you use Ysmenu for R4, you have to put TWO r4patch.dat in your R4 card, one is this for b/w use, other one is the original r4patch.dat, you can use the R4wood file manage function to paste the one you want to use to the Ysmenu folder

 

This didn't work for me.... gave me errcode=-4. What should I do?

 

use the clean rom

 

It doesn't work without clean rom?
