The example you have provided did not respond correctly to the actual sentence. We are dealing with data (both singular and plural), in this case, specifically the save data, thus I'm pretty sure it's singular instead of plural.

Okay to explain to the unknown, In the wrong translation above, This save data cannot be used because customizations used by the save data has been deleted, at first the subject is save data which is singular, but later in the sentence after the conjunction because, the subject changes to customizations which is now plural. This is why my translation is correct.

All these translation are corrects (I mean, originals one)
"ceinture" is feminine, so "noire" and "bleue" get an "e" at then end.

"Rien de place" means absolutely nothing. (I guess he isn't French)
Plus de place is right.

PS : I'm French
PPS : I'm going to edit my 2nd post now.

Nah, not all colors are according (this verb exist in english?) to the nouns.

If you want the list :

Every colors you see takes an "e", the others doesn't change.
