cheat programs

[K_I_R_E_E_K]

Yes there's an AR code called EXP Mod that will define the amount of exp you gain from each kill. There is a code that forces enemies to drop rares 97% percent of the time, as for making more enemies, I'm sure there is, but there isn't a code for it

no,no,no
i'm not refering to cheats (ar,cb,gs...)
a program(s) that will let me change the game without interfiring with the game
example: with a rom hack utility for a genesis emulator you can make sonic jump higher, run faster......(no cheats, just a different game)
like pso i would like to make my own pso with stats different from the original.
