The PSP Scene has seen some great releases, many of them apparently dead or simply not updated, As a fan of emulators above all else i would love to see a new release of PS1P which is the best Playstation Emulator for the PSP bar the Official Sony Emulator.
Another emulator would be Sougens PSP Genesis one of the very biggest emulators at the time and as with PS1P both were released exclusively on DCEmu Forums (unlike sites who would have you think were released on their forums)
3rd Emulator that really needs an update must be the Port of Mame for the PSP and more importantly the port of Chui`s Mame4All emulator ported to the PSP by Kech.
Another project that i would dearly like to see news of would be the Snes emulator Snes_TYL by Yoyofr and co.
On the gaming side i would love to see a new version of Iris a project by our very own PSmonkey which really took the PSP Scene to a new level and boasted such promise. Speaking of PSmonkey his Nintendo 64 Emulator for the PSP showed such promise and is another that sorely needs to be revitalised.
Now i would never bug coders to restart projects or release new versions but these are projects that are so great that its a crying shame not to see new versions of them.
