While EA was kind enough to include a very basic debugger, running before the actual game boots, and that reports any 'common' error (typos, misreferences ...), there are some errors that we have to handle, the 2 main ones being Worldbuilder errors, and game.dat breakdowns.

We know for a fact that EA has some tool to handle game.dat errors, since such errors create a file after the process has shut down. That file is a memory dump, also known as Core Dump.

(note: this error will occur if the game cannot access your INI files correctly, probably because you have set them wrong)

Now, if all errors were like this, we would all love our job as coders, and simply follow the instructions given by the debugger. But some errors will just create a dump file, and won't report anything to you; this tutorial is thus here to help you solve these problems, so stop hitting your head on that wall and read on ;)

wise words indeed,

though it may be worth mentioning that sometimes the best (or only) way of debugging is to brute-force it: to slowly change back all the last things you edited until the game works again, not nice but sometimes necessary (is currently having to do it)
