If it has not been aproved wihtin 2 weeks, the cover was likely rejected. Unfortunately there is no response.

Every cover has to be added to the database manually by a cover admin. If you have a cover for a game not on the list, just upload it under any other game in the same category. The admins will sort it out later.
I took a quick look at your covers. My guess is, that they will probably be rejected, because of the low resolution artwork on them (especially the gameboy cover).
But at the moment the site is broken anyway (see this
thread) and no covers can be added to the database. No word yet on when this will be fixed.
