I have dsi xl which used to have firmware version 1.4 and I could freely play in ROMs on r4i sdhc white "new" (2012 I guess). But now I updated my dsi to 1.45 fw after I checked it compatible with my flashcart and now it blocked. some details: wood version v1.62 updated card firmware (spongebob icon) I believe this is my flashcart. I can still use the cart with by brother's ds lite. It never worked on my 3ds. Is there anything that I can do?
