First, install Fallout 1. No need to add any patches or fixes other than the ones below - 1.2.1 adds in children if they're missing from your game, and includes all the stuff from the official patches.
- Team X 1.2.1 EN RC-1
- Team X 1.3.5
- [optional] NPC Mod for v1.3.5
- [optional] No armor-changing for NPC mod
- [optional] Wasteland Ghost RP mod (FO1RPv10b1), includes Invasion Mod plus more content. Cannot be installed with Wasteland Ghost's Invasion mod.
- [optional] Wasteland Ghost invasion mod (FO1RMp1v10b2), doesn't contain part 2 in above's readme. Cannot be installed with Wasteland's RP mod.
- Fallout High Resolution Patch 4.1.8.
- sfall1_v1.7.20 -> no longer requires any CRC input, has some good QoL options like show weight, take all button, "friendly fire" perk enabled by default (a FO2 feature). Lots of good stuff.
You can download all of the above in a single zip,
