My worries are under the policy we must have with the games without existent covers or really hard to find in good shape (download services, satellital, hacks, etc). There's many people that love custom covers when is hard to find a good cover or when they have a fantranslation that converts their japanese game on a unnoficial western release. My point is adding a label to custom covers next to the regional ones, like JP, US, EUR, CUSTOM to have
everyone happy. In my case i made some custom covers to satellaview, nintendo power snes titles to avoid the lack of real covers of this titles and understand some people prefer unified custom cover of systems like neogeo, etc.
My suggestion is here, what do you think?
