Final Fantasy Hacktics

Been using shishi for a year and made lots of custom sprites but now....havent touched it for 2 months, decided to do it again and ...nothing..... shishi 3.52 doesnt wanna load psp, only psx and the newest shishi doesnt wanna load too big files... and to top the whole shit off, exporting bmp in both shishi only gives me a file the size of 123k!!!! Thats twice the size you are supposed to get....WTF gives??? Im so pissed right now, messing with this shit all day and no solution....any ideas?
