i've added this to the other thread, but here is the same information:
Here is my current standard writeup:
One thing that can at least reduce the frequency of the problem is to make absolutely sure you both are using the same EXE file ... you can compare byte count ... date time stamp (which will usually be adjusted by time zone) or even use a CRC utility, there are a number of easily downloadable ones.
As Allies (or Axis) - there are a couple of things you can do to try and prevent sync bug... it is related to the amount of memory you have.
SO - run the file from a (preferably cold) boot, ie - don't load anything else before you finish running the turn. Make sure you have any memory hogs in the background turned off (i had some problems with things like screensavers, esp things like SETI@HOME).
Set your virtual memory settings up to maximum.
Control panel -> System -> Advanced (tab) -> Perfomance (click on Settings button) ->
Advanced (tab) -> Virtual Memory (click on the Change button) -> select Custom Size and make the size as large as you can make it
This can SOMETIMES get rid of problems.
You can also ask your IJ opponent to not use the ESC key during replays - some people insist that this can cause (or intensify) the bug.
Actions with PT boats seem to also cause problems, esp. strafing PTs. One game i had would invariably start a replay problem when this happened.
Otherwise use the Pompack Patented Procedure to restore sync:
1. Japanese player, receives Allied turn.
2. Japanese player turns off COMBAT REPORTS
3. Japanese player watches combat, enters orders and sends to Allied Player. (Japanese player does without combat reports and SIGINT for one turn; take good notes during combat)
4 . Allied player watches replay with COMBAT REPORTS ON (AFAIK)
5. Allied player enters orders and sends to Japanese Player
6. Japanese Player receives allied turn, turns ON COMBAT REPORTS
7. Japanese player watches combat, enters orders and sends to Allied Player.
