I dont understand what you mean by "make the ball move". But here's a little hack that will make the ball animate:

At address 0x44E2AC patch the code to PUSH ECX (0x51)

Did you want the ball rotating or something else?

No no. Just bouncing to the 4 walls. But remember: no patches!

geeko, you have a TTimer in the form to control the ball movement?

Not a problem!

Fun crackme, although I cant imagine how this could be used in the "real world". ;) But its a nice reversing exercise, of course!

Hint: Think in a grid-like way! ;)

As usual, will write solution if/when possible...
