Having trouble running JPCSP

[Oonoki Tsushikage]

Hey guys, as you can see i'm new here. I downloaded the JPCSP to play naruto Ultimate Heroes 3, butt, it doesn't even open, CMD opens very quickly with this message:

"Error occurred during initialization of VM
Could not reserve enough space for objects heap
Could not create java virtual machine."

I already reinstalled java and it doesnt work

Configs: Windows 7 Ult. 32-bit SP1
Intel Core2 Duo CPU E7500 @ 2.93GHz, 4GB RAM, nVidia GeForce 9400 GT

Please help me, i want to play that game *-*

And another question, whats that "Encripted, decripted" game? I dont get that ._.

I'm brazilian, sorry for my english.

Bye

It seems that something is using your ram,jpcsp needs at least 2 gb to run,you have 4Gb so it's probably some program that uses your ram.About the encrypted games:Encryption is the method to make information unreadable,only the owner can read it,a decrypted game is readable by every one

I had the same problem with the emu and if you want that's work, change this line of .bat and replace number by this one :
-Xmx900m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=128m.
If it doen't run, decrements the 2 lasts numbers until 64m and finally if it doesn"t run always, decrements xmx about 50m step by step and try each time. After the emulator can run but if you decrease the memory allowed by jpcsp, the program will be slower to run your game (especally, the new games).

Hey the, thank you, it worked, and i increased the memory, but then the game dont load... With mem at 512 it loads, but at 1024+ it just shows a black screen. How can i fix that?
