Today Wood has been updated to V1.50, the main fixes for 'pocket monsters'. And wood developper also released a an important note of distinction. just take a look.

QUOTE: Important Distinction
Now, there are so many fake Wood R4 versions which have nothing to do with me. Only Wood R4 for the original R4, R4i Gold (, R4iDSN (, and AK RPG are supported by me. I can only fix bugs for these specific releases. Do not post bug reports or ask for updates to clone cards running a fake version of Wood.

QUOTE: Change Log

  • 'pocket monsters - black 2 (japan)' fixed.
  • 'pocket monsters - white 2 (japan)' fixed.

From the distinction, we know that only 3 R4 cards are really using the wood firmware. so if you want to buy a R4 Card for your 3DS, you should just buy the r4i gold 3ds from which is this one: R4i Gold 3DS Wood R4i 3DS flashcard For DS DSi 3DS Don't buy other r4 clones.

And today team also has updated the r4i gold 3ds wood firmware from V4.19 to V1.50. if you have this card, just download the new firmware and then you can play the pocket monsters - black 2 and pocket monsters - white 2 with r4i gold 3ds card.
