There are a lot of retro handhelds, and a lot of them can’t run Nintendo DS properly with actual touchscreen support. So here’s my list of retro handhelds that have 90% or more Nintendo DS compatibility and are safe to purchase for Nintendo DS specifically with actual touchscreen support.
However, the best way to play Nintendo DS right now is still on an actual Nintendo 3DS or DS. While emulation is there, the lack of options for dual screen devices and having to use touchscreen make it a bit cumbersome to play.
Here’s the list (from cheapest to most expensive):
