The Capcom Arcade Collection for PS2 could be ok, but I think it will be fit equally in the Arcade category. Probably the idea of creating a new category for PS ports (PS1-PS2), especially for the loading stuff would take some seconds more for the gameplay. But thankfully in new PS ports like PS4-PS5 1942 could be played, too. And other platforms by emulation using Mame, Bizhawk, and all FB Neo stuff, along with MiSTer FPGA all those are a choice to play.

Additional reply... NESClassic Mini is scrapped because NESClassic sounds unnecessary to add since NES in emulation and original hardware is already considered a classic.

Besides, this thread was written by using similar words (copy/paste mode in words) in other leaderboard like Double Dragon II: The Revenge (NES), doing the same request.

Done. NESClassic Mini added as extra platform.

Retroarch can be used since it is compatible core for other gaming systems like Mame, SNES9x, FBA-FBNeo, and other ones and also used for Retroachievements. The only exception in Retroarch is the usage for smartphone/android which most leaderboards won't allow it.
