How to trigger Emil near Resistance Camp in NieR Automata™ / Type-3 Fists & Anger's Folly location

To make Emil appear near Resistance Camp for ability to buy last weapons in the game: Type-3 Fists and Anger's Folly, you need to follow next steps:
1. Load game at Chapter 14-01 and Transport to Desert: Camp
2. Follow path to City Ruins and you'll see Emil, shoot him and buy anything from his shop
3. Immideatly make your way to marker at map to Resistance Camp, Emil can be seen at Resistance Camp route, but not always, shoot him as soon as possible
It must be RNG, but I found possible to trigger his shop with weapons loadout with only this method
