Like many UE4/5 games, R-Type Final 2 encrypts its resource files and uses a custom mapping format. To unpack or modify in-game resources, you'll typically need both the AES key and the .usmap mapping files.
Download AESKeyFinder, and follow the first method described in this guide. Copy RTypeFinal2-Win64-Shipping.exe into the AESKeyFinder folder, then run the script to extract the key.
In the current version, four keys will be extracted—only one of them is valid.
There are two ways to do this. The simpler way is to use UE4SS to export .usmap mapping files. Follow this tutorial for instructions.
Alternatively, you can use Dumper-7. Download or clone the project and compile it. Then use any DLL injector to inject it into the game process. The exported content will include the .usmap files.
