Hello,
I have a problem with the modem option of F!GP from microprose. I
get a message "datamismatch" very often. It seems that if a car
is standing still (0 km p/h) there is a mismatch.
I have a pentium-60 with UART 16550 and a 386-40 (DX) with a UART
16450. The frame rate has no effect on the "data mismatch".
I hope someone knows a solution to this problem.
Greetings,
Rolf
I have played F1GP through a null modem without any problems, as
long as the gp.exe file was the same in both computers. Have you
checked this? This is only the case if you have been using
editors to modify gp.exe btw.
I was running two Pentiums together, a P75 and a P66. It was
great, hope you get yours working.
Have you also checked the connection speed (baud rate) they
should be the same.

I really must get round to updating the FAQ to reflect this.
When playing linked, you must make sure that EVERYTHING is identical on
the two machines. That means (hope I don't forget anything):
- the same GP.EXE. If you edit it, make sure you copy exactly the same
GP.EXE onto both machines. Any differences will result in mismatches.
(Okay, you CAN get away with different colors, but you will get
confused. :-)
- don't forget that not just editors affect the game. Think about
QTyres, GPBHP/WCF1GP, GPFlags, ... As I said above, the best thing is
to copy the gp.exe from one machine to the other to get exactly the
same program.
- the same settings on TSRs. Most importantly, if you're using GPLap,
be sure to use the same version on BOTH machines. If using CCpit, be
sure to usethe same settings on BOTH machines. (You CANNOT play linked
and multiplayer with CCPIT unless there SAME number of players is used
on each machine.) GPPerf shouldn't matter but it doesn't work right
during linked play anyway.
Did I miss anything, guys?

Yes. There is a bug in the linked code that is a real ***. It
involves having only one or none drivers (ie human) in the race.
In other words, BOTH human drivers MUST be actively racing or you will
get a data mismatch error when the game is reloaded. Obviously, this is
only if you reload the game DURING a race and one or both of the human
drivers have crashed out.
This *** little bastard bit my friend and me over the past weekend. It
was Monza and we were both trying to catch Schu who was running away with
the championship (we have the AI turned up quite a bit). My friend crashed
out real early. My car had so much oversteer that I was run down by the AI
and passed for the lead (it happens sometimes ;). I got really frustrated
and crashed myself out as well.
Just as I crashed out, the modem link disconnected. I dutifully saved
the game as I exited the screen. When we reloaded this game later, it
gave us a mismatch error. There goes the season. The latest saved game
we had was for Belgium, but we had both crashed out of that as well
(however, the race finished, therefore, the mismatch bug was eluded).
Well, we tried to reload the bad game with the mismatch from Monza, but
it still had the error. We then selected to restart (the race in Monza),
however, the 2nd bug came about. This time, he was ME and I was HE.
This was quite interesting because both of our files said we were
selected as ourselves. What was more strange was that, obviously, I was
in HIS car and he was in MINE. In other words, my joystick controlled
his car and his mine. When I hit N on my computer, it said I was him.
Well, we tried to drive each others cars and ended up crashing out anyway.
Needless to say, we just accelerated the rest of the season, handing the
title over to Schu.
The m***of the story - If one, or both, human drivers crash out, make sure
that you finish the race!! DON'T save a game with only one human driver
or else when it is reloaded, you will get mismatch errors.
