what if you just replace getValue bytecode?
keim_at_Si at 16 Mar 2013 22:15
Yes, I can imagine it is a solution if I can detect the address of ABC on memory. But now I have few knowledge about ABC and how it works. Currently, I use ordinary cheat techniques only.

@makc3d: You know any good tools/libs for this sort of thing? I had to resort to hex-editing just the modulo byte and clicking 100 times, because replacing getValue bytecode was too hard.

yogurt had that kind of tool, it was bugy as hell but worked correctly in 50% cases :) do not remember exact name

I looked it up, it was yogda.com and it seems abandoned. You can still find binaries around, e.g. http://code.google.com/p/opengg-clean-player/downloads/detail?name=Yogda.1.0.564.zip&can=2&q=

modfied swf + local http proxy, or something more hardcore?
keim_at_Si at 19 Mar 2013 14:03
No, It's only in browser, nothing special to do except for memory hacking.
keim_at_Si at 19 Mar 2013 14:07
And currently this is the most challengable one.

modifying swf is kind of pointless, since you could just do .text = "100" and call it a day.

>you could just do .text = "100" and call it a day. yeah, but where's the fun in that??
