It is rather frequent that MMOPRG don’t provide logging for ingame messages like chat or hit points etc. To track and log those messages I was thinking about using CE, because it has an excellent memory browser. It is rather easy to find the messages in memory with CE. However, since messages are moving frequently between addresses and normally there is not a fixed address range where they get stored, a dump of those messages is not easy to implement. At the moment I see the following possibilities:

1) Active scanning within CE: i.e. memory is scanned in regular intervals for the byte array of interest using wildcards. Found messages are verified if they already exist and stored if not. With this, one is able to log messages. However, modifications to CE are needed and one is only able to log distinct messages. So there is the risk to miss some.
2) Code injection: The procedure that delivers messages have to be identified and a dll is injected that gets the messages and logs it. With this, one can log all messages of interest but the original program has to be modified. Moreover, a logging dll must be developed.

What do you think about this and maybe there are other suggestions?
