Here are some tips for people starting out, since it has steep learning curve, much harder to figure out then for example Dolphin:
-First of all, additional program called Sonic Stage from Sony needs to be installed or there wont be sound in a lot of games.
Some games need even more then this, they need Sound Forge from Sony and that one isnt free.
Fortunatelly, about 95% of games will work fine with only Sonic Stage
-Option "Saving GE screen to textures" should always be enabled, because its equal to dolphin's Internal Resolution.
It makes games render at higher resolution then native psp resolution, probably your desktop resolution or maybe some fixed high resolution, who knows
Like I said, steep learning curve..who would guess that option has anything to do with internal resolution, right ?
-Anisotropic filtering should be also enabled in emulator's options
-Fonts should be copied from real psp into flash0 folder. Jpcsp cant provide these fonts, because its illegal. Replacement fonts are provided, and they work fine most of the time, but some games have problems with it.
-Some games need more memory then default 1gb, java options xmx and XX:maxpermsize should be increased in .bat file which starts the emulator, but only advisable on 64 bit version
If anybody has any more questions, they can ask here or on jpcsp forum
