i'm playing golden sun on UO gpsp kai 3.4 test 3 build 92, and the overworld and battles lag horribly
GBA emulation on the PSP isn't 100%. Don't expect all games to work flawlessly. Also lol at Maplestory Sig EDITED SO GRAMMAR NAZIS CALM DOWN
For GBA emulation, I use something called "gbSP mod". I think it's a version of "kai", but it allows me to change the GBA screen size, which option I could not find in "kai". I am very happy with this version. Don't know about the lag in Golden Sun, I only played it for an hour once and did not enjoy it.
The Golden Sun games are badly coded/programmed, especially as far as emulation goes. There are a number of bugs and glitches, especially those involving with water djinn. You should really play these on a computer, or a netbook at the least if you wish to emulate it. As far as which emulator to use, Rydian did recommend the best version thus far, GPSP-J.
Yeah, my version of gPSP (I think it's Kai or J) also allow me to change screen size of the games. I can have full screen, stretch, zoom, normal.
Golden Sun 1/2 are one of the few games that still don't run at full FPS. All other games run perfectly. If you really wanna play it just get a gba emulator on your computer
