[Inichua]

I tried 'Silva's Tutorial of hex editing'but the problem is the game will not open "lf2.exe not a valid win32 application.
I use a Windows 7 OS and HexWorkshop v6.5
Can u tell me what the problem might be.
Should i do something extra before running the .exe file
Ps.
I dont how to debug
Plz Give a solution or else I will never be able to create my first project

What was it you wanted to do?
Whatever you changed probably caused it to be unrunable, but there is no way we can say what without knowing what you did.

all i did was to change Little fighter 2 to Saga Fighter

If I have counted correctly, "Little Fighter 2" is 16 characters long, whereas "Saga Fighter" measures 12. Where did the remaining 4 characters go? Did you insert any additional stuff? Did you remove them completely from the exe? What happened to them?

What about changing ""Saga Fighter" to "__Saga Fighter__"? yeah cuz it has to be 16 characters.

No it doesn't. It needs to be 16 or less(unless you change other sh*t), as long as the byte after the last character is 0x00 it's fine. C strings are null (0) terminated and windows api uses C strings.

@Inichua:

You broke the exe. Restore your backup and try again.

I tried for 11th time now it still dosn't work is there anything else u didn't mention yet? If no then ok.
Plus i didn't change anything else I guess. And i also want to know another thing. how to use more than 16 Characters.
