Usually the android emulators (Even if you have installed on Your Android RPG XP Emulator) runs with .dsv safe files, So You will need to convert them somehow but won't be as easy as just renaming save file with .dsv cause it can corrupt or even worse won't even allow to play Your save file anymore on PC. The thing you should be looking for is either .exe file (Your game file) or .rxdata file (Your save file) conversion to .dsv safely without corrupting data. Hope it helps!
