Well that really depends on how much they are willing to give you for the two games (based on popularity) and the DSL. It also depends where you trade them in and on how much the DSi currently costs. There's no way of finding out how much they will give you for the games unless you ask them.
The DSi has two cameras, shop and can't play GBA games. The DSL has no cameras, no shop and can play GBA games.
$100
No it's better to trade it in.
Some shops allow part trading, however, the Nintendo DSi does not need Nintendo DS parts. Gamestop is currently offering the trading of the DSL for the DSi. If you trade in your DSL then you can get $70 towards the DSi (which is currently priced at $170). :) Yes that is right but the deal is no loger avaible!!!
Good News Yes You Can But DSL Not DS Hope I Helped
Yes. You can play fossil fighters on the DS, DSL and the DSi. You can play all* ds games on the DSi. *Unless they have an accsessory that uses the GBA slot
Nope. Sadly, you cannot because some of the games require a camera, the internet, etc. The DSi can play all Nintendo DS and DSL games, however.
DSL is high speed.
DS - $69 DSL - $99 or $129 (depends on color) DSi - $169
the dsl ( ds lite) doesnt have a camera, internet, or a sound mixer, or a store online for more apps for the dsi (like the wii shop)
Sadly, no. DSi games cannot be played on the DS or the DSL. The DSi features games that are specifically formatted for it,and some can be downloaded from the DSiShop (online) therefore, the DSi can play all the DS and DSL games, but its games cannot be played on the older versions.
