Hello friend, thanks for the translation, I can help you translate the images and text my Spanish is neutral and I also think that the problem of the mods (which does not load the Spanish when it is saved) is creating the Spanish menu in the preferences.
cuando ingreso al juego me sale esto:
While running game code:
File "game/tl/Characters.rpy", line 317, in <module>
File "game/tl/Characters.rpy", line 168, in alt_font
NameError: global name 'Mr' is not defined
