You can, but you probably shouldn't unless you are a trained, professional electrician because you can seriously screw up your DSi, if it's a leap year.
no, you might have to mod it :)
no not really unless you mod the dsi itself along with cheats
You would have to buy a special hard mod such as R2 (i think that is what it is called). You can find more info by googling DSi hack. A good website to buy from would be www.dealextreme.com
you cannot get a dsi with dsi points
yes a dsi charger fits a dsi XL and a dsi XL fits the dsi
UK: DSi - £129.99 Dsi XL - £169.99 - £189.00 US: DSi - (approx) $149.99 DSi XL - $189.99
No, the dsi XL has a bigger screen than the dsi.
Yes, the DSi charger is the same as the DSi XL.
There is no "DSi lite" console but if you mean the DSi XL, it is fully compatible with DSi games(although you'll have to buy them twice if you want a copy on a DSi and a DSi XL)
I dont really get what your saying. But if your saying how to get internet for the dsi. Go to dsi shop > dsi ware > free > DSi internet
No, it's only on the original Famicom/NES, the Virtual Console for Wii, and the SNES, in Super Mario All-Stars. Super Mario Advance for GBA was a remake including SMB2's content, however this too is unable to be played on a DSi.
In America: A Nintendo DSi is $140; a DSi XL is $160. In Japan: A Nintendo DSi is ¥15,000; a DSi LL is ¥18,000. In the UK: A Nintendo DSi is £150. In Australia: A Nintendo DSi is $300.
