Hi guys, this is a port of a windows game called Dink Smallwood to the PSP. It's an isometric RPG originally made in 1997 about a farmer defeating the forces of evil.
This port works better on the PSP-2000 models due to larger RAM, but still works on a phat.
I didn't make this, but the developer doesn't mind me listing this.
You can download it from freedink.org under the downloads for PSP section.
The source code is available as well under the GPL.
The original windows version is available for free from RTSoft.
