snes.xscalefs (and yscalesfs) resets to lower value itself

Hello,

With the following options : Fullscreen -> Horizontal resolution 0 Vertical resolution 0 Stretch to fill screen 0 Scaling factor for the X axis : 3,500000 Scaling factor for the Y axis : 3,500000

Setting are correctly saved in .mednafen/mednafen.cfg

cat .mednafen/mednafen.cfg | grep snes.*scalefs snes.xscalefs 3,500000 snes.yscalefs 3,500000

Game starts fine in fullscreen with 3,500000 scaling factor.

But when closing/launching again the same rom, it resets itself to 3,000000 for both. I tried to start with a blank config for both mednafen & mednaffe to rule out corrupted config file but it still happens.
