3 bytes to crack a small game

In one breath, I downloaded several small programs from the sky download network to practice algorithm cracking.

Due to copyright issues, I often practice foreign software. I caught a very simple algorithm and had no interest in it. I just wanted to try to crack it in the shortest time.

This is called PegIt 1.1.9 very simple: http://www.skycn.com/soft/35366.html

Before cracking:

After cracking:

You only need to modify three Bytes:

0040C000/$8A81 79070000 mov al, byte ptr ds: [ecx + 0x779]
0040C006 \. C3 retn

To:

0040C000 B0 01 mov al, 0x1
0040C002 C3 retn
0040C003 90 nop
0040C004 90 nop
0040C005 90 nop
0040C006 \. C3 retn

That is, assign the value of al to 1. In fact, you only need to modify the first three bytes, 8A 81 79 to B0 01 C3.

It takes about 2 minutes to complete the process. It is intended to update the space.
