Of course, There's a way
U can copy savestates from xbox located in the directory E:\TDATA\a64fea57\game_name(In numbers) and copy only file .fla to pc
Then download 1964 emulator and copy the file .fla to the save directory in your pc, this is for emulate the games in 1964 emu in your pc, but u can convert the 1964 savestates to project 64 v 1.6
How to export your savestate from 1964 to projet64:
Open the game and load previous .fla copied from xbox and Go to File option in 1964 emu and click on the option : To Project64 save state File.
Then u need rename the export file to the current for the project 64 emu and compress or edit the project 64 savestate.
This work for me.
