pRO Episode 27.2 Malangdo (Meow Meow) Patch Hexed Client

If you’re wondering why your old hexed client is not working anymore or if you’re looking for a new hexed client for the recent Episode 27.2 Malangdo patch, then you’ve come to the right place. Actually, the old hexed client is still working (The exact size is 4,847,616 bytes or 4.6MB). If that’s the size of the current hex that you’re using, back it up first before patching, then copy and paste it again in your hexed client folder. Check out my old post here for instructions. If you’re looking for a new hexed client, you can do the hexing yourself.

You can actually hex the latest unpacked Ragexe.exe in your RO folder, using this free hex editor. Then, just follow the same old instructions below:

Search:
85 C0 0F 85 D1 00 00 00 0F BE 05 A9 BD 89 00
Replace:
85 C0 90 90 90 90 90 90 0F BE 05 A9 BD 89 00

Now we just search for the line we marked.

Search:
85 C0 74 07 C6 05 87 5D 98 00 01 33 DB
Replace:
85 C0 EB 07 C6 05 87 5D 98 00 01 33 DB

That should enable you to run multiple ragnarok clients now.

To disable GameGuard just look at the above code for WINMM.timeBeginPeriod and look down a bit I marked it already.

Search:
E8 92 26 DD FF 3B C6 74 75
Replace:
90 90 90 90 90 90 90 90 90

That should disable GameGuard for the pRO client.

That’s it! You now have a working Malangdo patch hex!
