Eventhough the New 3DS XL is more powerful, I still feel like the DS Lite was a more polished system. It's a real shame that it never got an XL variant keeping the GBA slot. You'd have to go on AliExpress and buy an ML shell to give a DS phat the unofficial "DS Lite" treatment, and that's the best we'll ever get I'm afraid.
@Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.

For Items they start at 0x84738E58 and you just fill it with 63 all the offsets until you dont see any more 00 (its a LOT).
For characters level you start at: 0x8475A138 for the first one in your rooster and add +920 for the next one, you will see the ST, DF, etc. values a few offsets from the level one.
