[Pokemon Online] MC Tutorial -> OllyDBG

[Sketchy]

What you could do is locate the address from where the MoleBox unpacker calls the client's original entry point from and then insert a new instruction which will move the value 0xEB to the byte at 0x4F8944 right before the OEP is called. This is actually rather simple to do, first search the bottom of the stack for the last return address within the unpacker's memory range and then follow this address in the disassembler and get the address for the previous instruction and you have the address for the OEP call. Now it is just a simple matter of inserting a MOV instruction to move 0xEB into the byte at 0x4F8944 immediately before this and Bob's your uncle.

I can confirm that this method does work as I have done it myself using Olly to add the instruction, and I could tell you the address of the OEP call but what fun would that be?

that makes sense and i liked the idea. it's a general solution for the problem and makes everything else possible but i don't have any interest in pokemon online anymore, so if anyone feels like helping the players out there i wish you good luck. thanks for the info

I did all steps in the same way it's written but it doesn't work for me.
The PO MC Launchers says "Done. Press enter to exit" but Tibia returns error so I can't run 2nd client..

Can any1 check if its still working? Cause I don't know if it was my fault or it just stopped working [I heard that there was update some days ago]
