Seems like the fonts are messed up...
if you own the game, you could try to dump your game fonts into the JPCSP font folder :flash0->font
If not, try disable "use debug fonts".
Which emu version are you using, BTW?
actually i just got the game from thepiratebay (the iso file) and i m using version 0.6 2736 and can u tell me where i exactly find the "use debug fonts " ?
