Help changing some specific hex values?

[Som1Lse]

To change in windows title 'Little Fighter 2' to your game's title, open the exe with a hex editor or notepad++ and search 'Little Fighter 2'. When you found it rename it to your game's title and remember it should be of the same length of the previous title!

Correction: It cannot be longer.
Also use a hex editor and not Notepad++, because it isn't meant for these types of files, and even though it is possible to do so in Notepad++, it is vastly more complicated and thus using a hex editor is better. There is a hex editor plugin for Notepad++, so you can use that if you are interested.

For colors I recommend to search for the color values using cheat engine (link) first. The reason for this is that you can see the changes in real time, and thus find the correct values without having to modify the executable, and restarting it every time.
Then once you've found the addresses, you can then change them in a hex editor.
