im new need help

[rayjay9000]

so its my first time trying jpcsp because i heard it runs many games now if you got a strong enough pc and i tried it i used version 2373 64bit and when i try to boot a iso it says it dosnt support that format my other big problem is that after i opened the emulator for the first time configure it and close whenever i use it again i get a black screen so i cant run a iso or do anything than my only option is to close the emulator using the windows button

If you had chosen to looked up a wee bit further before posting your thread, you would've noticed there is a thread most likely already addressing your issue: http://www.emunewz.net/forum/showthread.php?tid=14984

I suspect you got 32 bit Java installed and this is why it doesn't work as 32 bit Java is not compatible with 64 bit JPCSP (duh).
