A'right. I dunno if anyone has it or not but it's as simple as the last one a guy made.
I've got the unlimited HP/MP too. Just read below.
1 - Go to ninja saga(use firefox or chrome)
3 - If using firefox select the process ''plugin-container.exe''
2 - Open CE and scan your gold
3 - Take that address( you might probably get something like this 03D93F58)
4 -Now if you want to increase your WIND stats, change the last digits to 90 ( like so 03D93F90) and change the value to 99999(It's better if it's 5 digits for value).
5 - For Earth(HP) change the last 2 digits to 95 and the value 99999.
6- For Thunder change the last 2 digits to 97 and the value , you know it 99999.
7- For FIRE change the last 2 digits to 89 and the value 99999.
8-Now the last one, for the WATER(MP) change the last 2 digits to 86 and value 99999.
If I find anything else I'll be sure to post it.
Edit : 7/4/12 ''1HKO still working using CE''
EDIT: 20/4/12 ALL STATS HACK!
NOTE: This works best with an old version of FIREFOX. I tested with the latest version of firefox and only FIRE stat worked, but with the old one, every stat worked.
