Hi, I'm new at romhacking forums, although I've been lurking this site for years now. I'm a great fan of rpgs, especially oldschool ones. I've just finished this game, and I've found it really interesting.
I only want to add my little contribution. Using emucheat, I've been able to find the memory adresses of the "next lvl" value for every character, so I was able to put it to zero, resulting in levelling up after every battle (makes level up a lot easier,

) Well, here you are
Tim: 00E118 and 00E119 (it's a 2 byte value, so put zero in both bytes)
Cherrie: 00E168 and 00E169 (same as above)
Celia: 00E1B8 and 00E1B9 (same as above)
Ray: 00E208 and 00E209 (same as above)
I know that playing with cheats is not as fun as playing the game the normal way, but it's useful for people like me who only want to follow the plot and not waste time raising levels and loosing against bosses over and over.
