It didn´t worked for me at least
I did a fresh installation of game (even deleting all folders related with FF7)
SYW V5 5.28 installed without errors
Game launched and get to the first save point saving my progress
Exit through game menu as usual
Launched again and SYW V5 alerted about my gamesaves were deleted and if i want to restore that, checked "yes" of course
Only "new game" option available, "continue" option is greyed out
The "official" gamefolder for savegames doesn´t have savegames
I tried to copy manually (copy+paste) from game´s backup folder but it doesnt work anyway (seems to delete every time i launch mod)
Edit: as aditional info, every time i launch the game all my controller/battle/menu configurations get reset to default (buttons, battle speed, colors, etc)
Kind regards
