You can play on nds, ndsl, ids and idsl.
Nds and ndsl are two hardware versions of the same machine with exactly the same skills. Ndsl is just thinner and smaller than nds. The locations of some interfaces have changed.
Ids and idsl correspond to nds and ndsl respectively.
I stands for iQue, N stands for Nintendo, and iQue is the authorized agent of Nintendo in China.
Ids series has all the functions of nds, in addition, it also supports genuine Chinese games (these games can't be played on nds series)-what we are talking about here is genuine games, and the rom downloaded online has no such restriction.
In addition, ids series is officially sold in China, so there are after-sales services such as warranty, while nds series is parallel imports, and there are no after-sales services such as warranty.
