I'm gonna be doing runs fairly soon, but everytime I close the game out it wipes all save data. I've done forum searching for answers before writing this, but all I've seen is changing stuff in the bio3.ini, which has done nothing. If there's a way to fix this I'd love to know because I didn't even get to finish learning the route (I made it to the final fight w blobby Nemmy)

Create a new folder and copy these folders to it from your old RE3 installation: DATA, DATA_A, DATA_AJ, DATA_J, ROOM, ZMOVIE and also the bio3_pc.exe. Start the game from this new folder and hopefully it should create a new config file and try to read any new saves you make from the new folder.

Thank you it worked!!
