User:Suicide machine/Research bunker/Alekhines Gun settings structure
Settings of Alekhine's Gun are store mostly in 2 files - smersh.shadvs and settings.scg.

File's structure is fairly easy to figure out, mostly because of a mix of String names describing it, followed 8-bytes (or 7) later by its value. Example:
0x0100:
........ModeWidth...............
................ModeHeight......
........................ModeBpp.
Hex representation:
000000000C0000004D6F64655769647468000000030000000005000000000000
0100000000000000000000000C0000004D6F6465486569676874000003000000
D002000000000000010000000000000000000000080000004D6F646542707000
Since PCs for many, many years have been using Little Endian, we have to remember to reverse the bytes to get our values, let's see then:
00 05 -> 05 00
D0 02 -> 02 D0
Now what's left is to convert these to decimal from hex:
05 00 -> 1280
02 D0 -> 720
Easy!

Structure of settings.scg is sadly way harder to read. Assuming all of these config files are generated the same way, we are dealing with different type of values (of different byte length) saved at specific offsets. Fortunaty the file is fairly short:
| Offset: | Type (byte length) | Description |
|---|---|---|
| 0x00 | String (4) | Probably prefix |
| 0x04 | Unknown (4) | - |
| 0x08 | Float (4) | Mouse sensitivity |
