Corrupted savegame is not detected as corrupted by the Player while it should

[Mimigris]

When testing the GetSaveInfo feature, I've tried to make some corrupted saves by manually adding garbage data in it.
I've managed to make a savefile that the Player accepts as valid while the RPG_RT does not accept it.
Save08.zip

On the RPG_RT, you can't see this save at all.
On the Player, this save can be seen in the loading scene. You can try to load it but it will result in an error with Map0000 not found. Also, if GetSaveInfo from the Maniac Patch is used on said save, the Player will crash.
