Transport Tycoon Forums

Have been trying out 2.5 beta 5 on Windows XP pro SP2 and it works great apart from every now and then, the game locks up (no movement on screen, mouse freezes, but music continues) although you can get task manager to run and it shows TTDLOADW.OVL running at 99% CPU usage. Have to terminate the process. If you then run TTDPatch again loading autosave game (or saved game), it works fine (ie. doesn't lock up at the same time). No crash files created because it didn't actually crash.

edit: same problem with beta 6

In beta 3 there was same problem. AFAIK it was fixed! maybe solution: moreanimations bigger by half, when its 5000 then make it 10000.

Follow the ollydbg-related instructions here.

There is a slight problem with using ollydbg. When TTLOADW.OVL locks up the display, you can't get any other apps to display on the screen. The ONLY thing that can display on the screen is the taskbar and task manager. I haven't found a way to do File > Attach in ollydbg because I can't see what is going on.

Have attached the ttdpatch.cfg file in case that is useful.

Try running TTD in a window instead of fullscreen.

That did it.

Hope this is useful.

I'm afraid not. Did you do the "Hit F7 once" step before taking the screen shot?

Sure did. Here is another go.

Strange, somehow your OS is different in a way than what I'm used to. These screens only show the Windows exception handler, not the actual patch code that's hanging.

OK, try pressing F8 until the first line starts with 004xxxxx, 005xxxxx or 006xxxxx (the only that's 7C95xxxx in your screenshots). Then send me that please.

Well it doesn't get very far. Have tried it a number of times and pressing F8 works only a few times and each time, ollydbg gets stuck as shown in the screen dump. TTDpatch seems to crash more frequently when running in a window instead of full screen.

I'm afraid then I don't know what you can do at this point, somehow the debugger isn't behaving as I think it should.

I'm assuming you meant "F7" there.

Does this solve the problem:

JohalaReewi, Do this for me:
Once you have TTDPatch locked up, Attach as per usual.
OllyDbg will pause the execution of the program...

You initially need to hit F9 (Or the play button up on the toolbar) to continue the program... so it gets back to it's locked-up state.

Now hit F12 (or the Pause button up the toolbar) in OllyDbg and see where it stops.

If it's still in a memory address above 650000-700000 then I think you should consider upgrading Video Drivers or DirectX.

This looks a bit better I think?

Yes, that one was actually useful, thanks.

It seems to hang searching for the end of a tunnel, while updating a signal block with a train in the tunnel.

This suggests that somehow the tunnel is broken and only has one end so that it never actually ends.

Check your savegame for tunnels, especially look at trains that are in a tunnel to see if they're alright.

Can't see anything obvious but this save game crashes on 6th Oct 1984 if you just load it and let it run.

Also happens with 2.5 beta 6. Started brand new game. This save game locks up on 25th Oct 1958 if you just let it run. Have also got ollydbg screen capture. Hope this is useful.

Screen shot of a train in a tunnel when game crashes.

Looks like there are some earthworks going on as the train goes into the tunnel. That truck also looks a bit out of place?

Can you try to disable autoslope if it's enabled? That looks like an autoslope bug when terraforming ...

Autoslope is off according to TTDXC. Should I try to switch it on?

Check post previous to screen shot for copy of ttdpatch.cfg.
