ok. So what game? From what I know of programming and file controlled data, I don't see any other place that the data can be changed except for in that INI file. Seems that that is where the chagnes are made, so that is where you want to change it. It's very possible that the game programers knew what the possible constaints of the game were and limited the abilities of the INI file input to certain value ranges. It's also possible that the values are read in once and then held in another file. There are a lot of possibles with this.
have you been able to modify any of the other settings on the other monsters and get them to work?
Also, are you makeing the chagnes before loading the game or after? cause you have to do it before or it won't work.
Good luck, and if you want more help, please detail your response. Need more help than a simple one word response...
Thanks and good luck
