New page

We're not doing a full patch or anything on the DOS version but I've got an IDA database going for it to compare a few things against. If anyone asks me for a DOS patch I will put them in The Little Box Of Screams along with the Amiga fanboys.

=== Possible thiscall format ===

A lot seems to use __usercall with int a1@<edx> at the start. I'm wondering if this is a __thiscall variant specific to some DOS compiler, where that should actually be int this@<edx> more or less across the board. Watcom perhaps? I don't have enough experience with DOS C++ compilers to know whether or not that's accurate.

=== Some functions ===

* '''cseg01:00038BA7''': char __usercall SimulationProposeMilitaryBase@<al>(int a1@<edx>, __int16 a2@<di>)
:: Cities with coastlines seem to have a 50/50 chance of getting a naval base versus getting something else! This is good to know for reimplementation in the Win95 version.
* '''cseg01:00049F2A''': char __usercall MessageBoxYesNo@<al>(int a1@<edx>, int a2)
:: Message format is an array of 32-bit near pointers to strings followed by a null pointer for termination.

=== Some variables ===

Booleans all seem to be the C++ bool type, so sizeof(bool) == 1.

* '''dseg03:000C82E5''': char bMilitaryBaseType
:: Same format as Win95 version
* '''dseg03:000C82E6''': bool bCityHasOcean
