Tutorial:
Hacking difference value non-DMA games
Tool(s) used:
CWCheat 0.2.1 REV.A
I can't find any non-DMA games to use as an example to find value that didn't show fixed value, I will still try to make a tutorial on finding them.
Objective: Finding the address for life bar (take note that I said life bar, it just show your character's life bar and no integer shown)
Game used: -
"How do we search the address of life bar? We don't even know the value of our life", alright it's pretty easy. First run the game on your PSP, load your saved file and take note of your character life bar's marking.
Hold down Select button button for 3 second, go to "Cheat searcher", and now go to "Start a new search for a difference" (this option is something like "Start a new search for unknown value").
You will see this,

First dump done!!
Select databasetype and modify data then resume search
Datatype: 8bit

By now I believe you should know which search type to choose, for fighting games it's more likely to be 8bit. Let's continue. Went back to your game and make some changes to your life.
After you make some changes with your life, go back to the cheat menu, "Cheat searcher", "Continue a search for a difference", if your life value is decreased then choose "less than before", if your life value is increase, then choose "greater than before". Or even better if you know the value that decreased/increased then you can simply choose "less by than before"/"greater by than before" respectively and put in the value.
Take note: Sometimes if you search using "less by than before" or "greater by than before" it might take a long time to search, and there's a probability that the game is hanged. Don't worry, there's always a solution. For example, if the value is decreased by 20, instead of choosing "less by than before" 20, you choose "less than before" same goes to increase value. This method might take longer time, but it's worth it when you found the right address(:
Just continue to change your character's life and search for the differences until you get a few addresses(just do some trial and error) or best, 1 address remain.
Hopefully by now hacking non-DMA games is not a problem for you.
