Theres no GBA slot for those games. (Which you cannot play Guitar Hero, or other games that need it) And if you use an Action Replay, those DO NOT work...
Not me.
I wouldn't attempt it because if you think about it, DSi must use more power than an ordinary DS because of the features. If u do put it in, the DSi may die after 10 seconds. I don't really know because I dont have DSi. Just don't try it. Or if you want to malfunction your DSi then you can. Also, the DSi case is slightly thinner, and you may run into spacial problems instead of just technical ones.
They are barely any different. The DSi XL has better screens and a longer battery life, but it's not easy to carry because it's much bigger. Since the DSi is cheaper, I would recommend that, unless you have problems with your sight, or if you would use it regularly with others (the XL is designed for other people to watch you play)
you cannot get a dsi with dsi points
yes a dsi charger fits a dsi XL and a dsi XL fits the dsi
i have heard that the games from the US will not play on the PAL system, not sure about that
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
