Unable to launch JPCSP from command prompt

[montcer9012]

It seems that Java arguments must be on the exact way they are; to fix the issue you must replace one lower case letter by uppercase. The mistake is on "-reservedCodeCacheSize":

"c:\program files\java\jre7\bin\java" -Xmx1024m -Xss2m -XX:MaxPermSize=128m -XX:reservedCodeCacheSize=64m -Djava.library.path=g:/emulation/jcpsp/lib/windows-amd64 -jar g:/emulation/jpcsp/bin/jpcsp.jar -u g:/emulation/jpcsp/images/hexyz force.iso

Anyway, once it is replaced by "R" JPCSP will start but the full patches are not allowed on next commands so you must place the batch file inside "g:/emulation/jpcsp/" instead place the full patch on the arguments; if you want it on Desktop or somewhere else create a shortcut; besides, it will allow you change the icon. The working command look like this:

"c:\program files\java\jre7\bin\java" -Xmx1024m -Xss2m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=64m -Djava.library.path=lib/windows-amd64 -jar bin/jpcsp.jar -u "images/hexyz force.iso"

Remember to add -r at the end if you want JPCSP load the game image once is started.

EDIT: Some users add optional Java arguments that need administrator privileges on Windows Vista/7/8; to properly start JPCSP like administrator, must add to the batch "CD /D "%~DP0"" after the "@ECHO OFF" on the very begging. More info here: http://www.emunewz.net/forum/showthread.php?tid=87454
