Abstract:
|
||
|
|
|
||
|
|
This game is divided into 3 programs:
|
||
|
|
1. The launcher (bshipl.exe)
|
||
|
|
2. Classic (bship.exe)
|
||
|
|
3. Ultimate (bs.exe)
|
||
|
|
|
||
|
|
The launcher is the only shortcut exposed to the user and runs the other 2.
|
||
|
|
However, the launcher and Classic both have a ton of problems that aren't
|
||
|
|
easily fixed with a shim.
|
||
|
|
|
||
|
|
Ultimate, is a complete superset of all the features of Classic and doesn't
|
||
|
|
appear to have any issues.
|
||
|
|
|
||
|
|
Therefore, the fix is to redirect the launcher to Ultimate and prevent
|
||
|
|
Ultimate from spawning the launcher on quit.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is a specific shim.
