Hacking DSi XL Firmware 1.48

[baxr6]

Hi all,

I have purchased a M3i Zero for my australian DSi XL.It says the firmware version is 1.48, but when I search for anything about M3i Zero core files I can only see 1.48.Does the M3i zero work on my version.and is the latest core 1.7.2 right for it.

Thanks
