Forcing Jpcsp to use more RAM?

[Finzy]

Is there any way to force Jpcsp to use more RAM? Currently the 32 bit version can only use about 2 GB max I think, and in games like Dissidia Duodecim, I'm always running out of memory after 10-15 mins of playing (since I have vertex cache and shaders enabled for better performance), and it gets annoying to restart the emulator every once in a while.

I have 8 GB worth of RAM and I'd like Jpcsp to use up to 50% (I think that's the limit since Windows reserves half for itself iirc), without needing to use 64 bit Java since it has no sound.

Yes, if you do following steps:

#1 - for 32-bit OS only:
------------------------------------------------------------
for Windows 2k/XP -> add attributes "/3GB /Userva=3072" in boot.ini, like this:

[Boot Loader]
Timeout=30
Default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
[Operating Systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Microsoft Windows Server 2003" /fastdetect /3GB /Userva=3072

for Windows Vista/7 -> run command line from administrator and type there

BCDEDIT /Set IncreaseUserVa 3072

wait until receive message with operation completed and reboot.
------------------------------------------------------------

#2 - adding LARGE_ADDRESS_AWARE flag
------------------------------------------------------------
Get 4GB Patch tool and patch java.exe
------------------------------------------------------------

After those steps 32-bit applications with LARGE_ADDRESS_AWARE flag could use up to 3Gb on 32-bit OS (and up to 4Gb on 64-bit OS).

What's the last JPCSP version you tried?

Obviously not the version released within the last month because if he had tried it, he would've found that the 64-bit version now has glorious sound.

Damn it, that should've been mentioned more clearly, I thought only videos worked on the 64 bit build. Awesome news anyways, guess I'll just install 64 bit Java and get playing then.

EDIT: The 4 GB patch worked just as well, thanks for the help!
