Hm the downside of this dmg hack only limited to the weapon.. what i mean is if you have different weapon, you need to find the code again by identifying that weapon attribute..
For level 25 subweapon with +25 upgrade and at *5.. you can try 1000;25;5;(price of weapon);48::50 ...... refine 25 to desired number like 9999... for trade limited *4 to *8 the code is 48.. also if you know the price of that weapon you can add there.. Ohh and if you mean you have level 25 but no upgrade (+0) with *5.. it will be 1000;0;5;(price);48::50....... then refine 0 and edit to 9999.. If any of those two didnt work, you can try to change the number order like e.g from 1000;25;5;48::50 will be 1000;5;25;48::50 etc.
