The various (V1, V2, V3) programs have special scripts that designate which Version the save game is for. Thanks to the Chain Game providers persons of different versions can change the script to allow the other version Players to do missions and save in modified form that will allow other version Players to use the save game.
V2 and V3 are the same, but V1 is different. Using the wrong script will cause the game to start at the beginning, or crash.
Since my base Game is Version 2, the uploader Converted it so you a Version 1 player can use it.
Game Tip:
Explore, there is a body armour in one of the wrecks. If you don't mind spoilers you may be interested in the 'new' Weapons Guide, too.Mission Tip:
To do it yourself, take off, fly North to the sea, Fly along the coast to the south of the target. A quick trip inland and back south to the sea. Then home. Most flying missions now are take-off, enter corona, and land. It's worth the trouble to practice. Later you can do this one overland.
