Datel Action Replay Max Duo for GBA & DS Consoles

Worked well. Have not tried the DS portion though since I was just looking for a GBA action replay.

The silver Action Replay Max Duo for GBA & DS is the newest version of the GBA Action Replay. These will fit and work on a GBA SPand DS Lite consoles. You can add codes manually or by using an USB cable and downloading codes from a PC. This device is only foruse with GBA games only! Some people confused get confused when they see the "DS" stamped on the device and think DS games aresupported, that's wrong. You can find codes for most GBA games by Googling, Action Replay GBA codes rather easily. This device is abig improvement over the older, Action Replay GBA(Red Label) version. They're built solidly, like a tank if you know what I mean.These are rare, hard to find and can be quite costly. If you can find one at a fair price, do so. They are definitely worth the money.
