Java games tons here

[admin]

crackzplanet dot com, under PDA, there are some gameloft games in category G.

I tried a few test test, and they were not runnable on my E680, maybe someone whould like to waste his time trying out more?

By the way, why does jar not really openable by all phones? I thought it has a standard

[ycyas]

example:
nokia has an own standart by java and api's.

it depends also on the programmer who wants programm for every phone brand/type or not.

can we reverse enginner it to make it possible??

Reverse engineer just to play a game? I think the people capable of doing that should spend their time on things better than that.

1) Extract the jar file.
2) Use this tool to reverse-engineer the java bytecode files:

Java bytecode is almost a human readable thing but the jar packages used in phone games optimize the classes, the methods(functions) names are modified to have the name small as possible to save space(java bytecode is a lame thing that saves the function complete name...). The reversed code still readable but it became such a mess with functions name lika A() B() C()... Nokia also have a big tree of classes to deal with...
I think it's better thinking to port games like doom

hmm .. can use this reverse method to check the keys in a java game ??

if the jar is not protected like the ones that come with the phone... if it is drm protected you got big trouble to decompress the jar file.
