[joshisposer]

Yeah wat carlix said, wat will this do to the psp? I mean, it's not like it's in the browser. I mean, homebrew is homebrew and i respect the guy for taking his time to make this.

does this play cell phone games?

[Exoskeletor]

yes can we play jar games?

[kiore]

but ain't most jar games set ,around 128x128 pixels , that gonna look like crap on a psp screen.

Screw that, EMULATORS!!!! Nescafe....... etc

[dejkirkby]

Tried 4 or 5 .jar games and the program didn't recognise them.

[XioN980]

to run a .jar try extracting its contents and running the applications main .class file, it wont work for everything and you can only use one at a time. It wokred for one game i tried as a test :)

[cal360]

This is great hopefully we should be able to play a lot more games on the PSP now

[carlitx]

ok wtf does this thing do someone elabortae in english

[flu0r]

Funny to watch people complaining about non-working jar games and asking what good a java-runtimeenvironment will do on the PSP.

1000 thanks cklgamis, there are peeps out there who honour your work ;)

[scottyboynow]

Run extracted jar. games (like mobile game)

[LilSwish722]

PLAY RUNESCAPE ONLINE!!! Nah, that woudn't work. At least not right now with this current build. Maybe for the next version they can allow acess to the PSP Internet Browser so we can play online java games. THAT would be aweomse.
