Hello,
I tried playing with the +relay, but I only get about 2fps playing the game so it's pretty hard to play enough for it to freeze (sometimes it's only a minute or so in, sometimes an hour or more) I played for 15-20 minutes and am feeling pretty nauseas :) the trace file's around 7.2G,
I have written a little perl script, what helped me to do small traces from some programs, when you need dump trace info from a advanced point of a program.
It is very simple of use. Run wine with for example:
wine --debugmsg trace+all winmx331.exe 2>&1 | wineparse.pl
Wineparse goes reading the log lines, and buffering the last "n", by default 500, but you can modify it. When it finds the line what you were searching (in my case: wine: Unhandled exception, starting debugger), it dumps to the file "/tmp/winparse.log" the last "n" buffered lines.
Probably it is possible to do the same using a combo of sh command lines, but i didn't want to think too about it hehe :)
It should give you some more fps, than dumping the complete log to disk. I wait that it can help you.
Good luck, Regards, Carlos.
