Not sure why anyone who collects games would buy these reprints. While they are legal (because LRG obtains the rights to do them from the companies who currently own the rights), just like LRG's other reprints of old console games for GB, NES, SNES, N64 etc., they aren't actually licensed by the platform owners (Nintendo, Sega, etc.).
Meaning, unlike their games for current systems (PS4, Switch, PS Vita), these console re-releases aren't official. So for collecting purposes, they have little to no value. Even completionists who try to collect complete game libraries don't need them.
