Global Memory bank
This is a structure of significant size that holds over 2500 DWords related to the global situation. These range from logs to screen resolutions to sound handlers. Documenting this is a very difficult task as it is accessed all over the executable code and usually passed to other functions as pointers. As such this list is likely to change a lot and some of it might start off completely wrong. This only applies to the PC version and possibly only v1.02 of the '98 release.
| Memory pointer | Initial Value | Function |
|---|---|---|
| 0x000 | 1 | |
| 0x004 | "APP.LOG" | Log file name |
| 0x00C | Current bits per pixel | |
| 0x030 | Related to time (elapsed time?) | |
| 0x038 | Related to time (start-up time?) | |
| 0x058 | hInstance passed to the WinMain function as the result of a GetModuleHandle(0) call on startup. | |
| 0x05C | Window handler pointer created from a CreateWindowEx call | |
| 0x848 | 0 | Width of border on left and right |
| 0x84C | 0 | Height of border on top and bottom |
| 0x850 | 640 | Display's width in pixels |
| 0x854 | 480 | Display's height in pixels |
| 0x858 | [0x850] - [0x848] | Display's top left X coordinate in pixels |
| 0x85C | [0x854] - [0x84C] | Display's top left Y coordinate in pixels |
| 0x934 | Method used in redrawing screen | |
| 0x954 | 640 | Application's width in pixels |
| 0x958 | 480 | Application's height in pixels |
| 0x95C | Requested bits per pixel (should match [0x00C]) | |
| 0x99C | 90.0 | |
| 0x9A0 | 5.0 (then changed to 125.0 | |
| 0x9A4 | 2000.0 (then changed to 50000.0) | |
| 0x9B0 | 0 | Seed for randomizing function (current time is used if value is 0) |
| 0x9B4 | "DEFAULT" | Process Name |
| 0x9B8 | "DEFAULT CLASS" | Equally un-inventive process class name. |
| 0x9F0 | 0x4089C5 | Library access function. Will load all LGP archives. |
| 0x9F4 | 0x676605 | If passed argument is 0 this function sets it to 1 |
| 0x9F8 | 0x408FA6 | "Main" function called first when a game is loaded or started |
| 0x9FC | 0x4090C7 | Function called when a game is quit via menu (PC only?) |
| 0xA00 | 0x4090E6 | Event Driver pointer |
| 0xA28 | 0x409CF2 | Function to set up window for playing a movie file |
| 0xA2C | 0x409D66 | CD Check function to make sure correct disc is present |
