Kingdom Hearts: Birth by Sleep - US - ULUS10505

the problem is not everyone has a lot of ram, for jpcsp to be usable for a wider range of people these settings need to be low (user can up them if they need)
if all the settings are set to a use a lot of ram people with low memory will get more crashes or possibly jpcsp not even starting up, not to mention they don't help every game since it takes away from the xmx setting.

As a former 1GB user of JPCSP I know very well. (see my threads about ZHP Unlosing Ranger or Disgaea 2)
But 128MB + 64MB = 192MB fixed memory usage I don't consider too high for todays low-end computers, really.

as for the ReservedCodeCacheSize setting, I really don't think it does anything

It does, believe me. Aedis Eclipse, which I've played through just a while back, needs this to be set at 64m minimum, otherwise it will always crash after a short while of playing.

I've never seen java disable the compiler even though it says so in the console, so could possible remove the ReservedCodeCacheSize line and add the extra 64mb to the more useful maxpermsize setting for 128mb

As already pointed out, ReservedCodeCacheSize=64m is a minimum required for Aedis Eclipse. Kingdom Hearts seems to require even more as of the log posted just above my former post.
