Automatic save conversion deletes memcard file

[theflyingzamboni]

Users may want to keep the actual memcard file for further use and could have it accidentally deleted entirely if they just move the file in. Conversion should therefore maintain the original file. Could move it to another folder to keep the saves file cleaner, but this could result in people not realizing their memcard was preserved, so it may be best just to leave it there, or put it in a subfolder.
