Default Options	Set the contents of the Options menu when the game launches
Delayed Load	Insert an artifical pause on every load (e.g. for practice)
DirectInput Background	Allow DirectInput controllers to be used when the game is not in focus

This program used to occasionally be flagged as malware by a small number of antimalware programs using machine learning (ML) definitions. That doesn't seem to be an issue any more, but have this VirusTotal report for version b7 anyway.

Instructions

Ensure that Ultimate ASI Loader is installed by installing one (not both) of the following:
- V's Fix (recommended)
- Ultimate ASI Loader (x86 version - copy
```
d3d8.dll
```
  to the game's
```
bin
```
  folder).
Extract the zip to your MGS2 installation so that
```
MGS2.asi
```
is in the
```
bin/scripts
```
folder.
(Optional) Copy
```
MGS2.ini
```
from the
```
MGS2.ConfigFiles
```
folder to the
```
scripts
```
folder.
For any mod you want to use:
- Either: Copy
```
MGS2.NameOfMod.ini
```
  to the
```
scripts
```
  folder...
- ...or: Copy the contents of that .ini to
```
MGS2.ini
```
  if you want all your settings in a single file.
- Also edit that .ini in a text editor, if you want to change the mod's configuration away from the defaults.
Most lines are commented out with
```
#
```
symbols, so delete that symbol to edit the line. If a commented-out line has a value already, that value is (usually) the default.
Launch MGS2.
