I have the first R4i-Sdhc with firmware 1.08b. On the website they stopped supporting the dsi v1.3 or lower carts. so i was wondering, since they are based off the dstt or dstti makeup, is it possible that i can use the latest dstti firmware and just rename the important files in it? Could anyone help me with this question, cause ive already used the search box. thanks in advance.
