I bought these flashcards long ago for dsi. they work fine. I will try them in the 3ds soon, I have read all the forums but it's too confusing for me. So my questions are : both cards with latest wood 1.64 Both cards have different icons. rev C = http://www.r4ids.cn/images/dolasho.jpg rev D = http://www.yallgame.com/piceasy/upload/images/Z44T.jpg in the wood kernel help info both show as the same. dsi 1.45, 3ds 6.20. <-- does that mean they are already patched from factory? Do I still need to patch them? if so, can I try the latest patch: "The 3DS V6.2.0-12 Patch for R4i Gold 3DS is released now! (for R4i Gold 3DS card only)(Aug.6th,2013)". or do I need to patch the previous one first? I hope someone knowledgeable can explain it to me if possible. I will appreciate it.
