Just added the nfo and game icon. Apparently there's some antipiracy here, which is already fixed. Copy/pasted from DS Scene-

How to play "Estpolis" on your DSTT and R4
For other than R4:
1. Download
http://www.megaupload.com/?d=KZ4Q4UJL and get a Patch.exe file from the RAR archive.
2. Drag your ROM and drop it onto the Patch.exe. That's all.
For R4:
1. Use the Patch.exe in the folder of "For R4"
2. Rename your ROM file to "Estpolis.nds"
3. Put the Patch.exe to the same folder of the renamed Estpolis.nds file.
4. Execute the Patch.exe. That's all.
Note:
This path is not only for "Estpolis". It's one of game to be patched by Universal Child's Play Patch.
The file having the ".bak" extension is the backup copy of the original nds file.
