[PSP] [2005-2010] Minimalist videogame using wifi networks around

I'm looking for a PSP game, which I'm 90% sure was an homebrew, which displays wifi SSID on a 2D map (depending on how far they are, it should have checked the RSSI levels of the 2.4GHz signal). The player as to wonder around to discover new wifi networks and gather points.

It wasn't that fun but the necessity to do some wandering around surely was a novelty back then, and I'd like to find it again (even tho I'm pretty sure it won't work on emulators).
