I just bought an R4i 3DS cart (this one), which from what I've read on here is a DSTT clone. So does this use R4 firmware, or is it DSTT? Can I use R4 Wood or YSMenu with it? Or do I stick with the proprietary firmware (the latest website has is 1.44b)? I'm curious as to what this cart can use since I'm gonna lend it to my niece until my EZ-Flash Vi is fixed.
