GTA Chinatown Wars for Nintendo DS has been leaked online just before the weekend, and many users at GBATemp.net (linked above) have confirmed it works with a variety of carts.
The official streetdates for the title are March 17, 2009 for North America and March 20, 2009 for Europe.
Apparently it works on the G6 real with latest firmware, SCDS1 (clean, no patches with latest firmware and AKRPG (AKAIO).
To quote: "At the start when you turn on your DS with your supercard, go to the GTA NDS file on the top screen, then in the bottom screen you will see the file information, at the right hand side you will see ''SET PATCH'' click that, and you will notice that the top one is ''ENABLE PATCH'; which is ticked, well untick that and start the game!!"
Also, the DS-X is reportedly capable of running it with the MaxCrassMethod and others by using this save game file on your cart:
Downloads: Grand_Theft_Auto_Chinatown_Wars.SAV / GTA_CTW_YGXE_00.sav / 3517 - Grand Theft Auto Chinatown Wars (U)(Xenophobia).SAV
Download the save file, then convert the save file, for the source put R4 and target put your flashcart.
