The DeSmuMe, and also other Nintendo DS emulators, can be ported to the PlayStation Portable.
It emulates, almost perfectly, all known 2D graphics; has some small issues such as the color bit depths.
So if DraStic does not hit downloads in millions by the end of this year, I will be very surprised.
YopYop156 stopped development on the DS emulator at version 0.
But even French version of DeSmuME is easy to navigate through menus as it has a similar users interface to DSemu.
I can honestly say that I am proud of Exo yet I feel jealous because his App is just really amazing that I find it absurd how damn good it is.
