Reverse Engineering

Graphic

Microsoft Minesweeper uses the BitBlt function to draw its mine area.

loop-bitblt

0x01005334 and 0x01005338 are the addresses of the mine area's width and height. When the game executes at 0x01002700 for the first time, the mine area is empty.

empty-area

The stack is shown as below:

bitblt

According to the declaration of BitBlt, the pixel coordinate of the top-left corner of the mine area is (12, 55). And the side length of a block is 16.

c BOOL BitBlt(HDC hdc, int x, int y, int cx, int cy, HDC hdcSrc, int x1, int y1, DWORD rop);

Mine Data

At 0x01002669, the game reads mine data from 0x01005340.

read-mine-area

For the following mine area:

game-end

The data around 0x01005340 are organized as:

mine-data

It is clear that each 0x8A means a mine and 0xCC is the activated mine.
