what is this sfall IIRC?
It's a set of engine modifications for the classic game Fallout 2 by Interplay. Includes fixes for bugs in the original engine, allows fallout to run correctly on modern operating systems, and adds additional features for modders.
The main features are:
Increase movement and combat speed to up to 10x normal.
Play fallout in a window or in 16 bit colour mode.
Use d3d9 in place of the usual ddraw.
Use the mouse scroll wheel in the inventory, barter, conversation and save/load menus.
Assign a use to the middle mouse button, and adjust mouse sensitivity beyond fallouts normal range.
Adjust or remove the 13 year time limit.
Fixes the broken pathfinder and sharpshooter perks.
Adds some additional script functions for modders to use.
