The covers for Jikkyou Oshaberi Parodius and Trials Of Mana are both the wrong box art for the wrong game. Both of these covers have art of the entirely incorrect game. In neither examples are any of the characters you have on the covers for those in the game you made the covers for. Your Trials Of Mana box uses art and characters from Secret Of Mana, the wrong game and none of the characters are in this game. And Jikkyou Oshabery Parodius is using box art from the Pardodius Da game on NES and MSX and as such none of the playable characters or even any of the enemies are even from that game, they're from two whole games prior in the series. Please fix these and use proper art from the correct games.
Also WWF Royal Rumble, Breath Of Fire II, Dragon Quest 1&2, Hearthrob Memorial, Dragon Quest 3, and TMNT Tournament FIghters at least are missing any kind of MSU1 box art of any kind. And also there is no Lufia 2 MSU1 box art provided, only for the Japanese version of the game with an entirely different title.
"The only Genesis games worth playing"
Bro. There's no Alien Storm, Altered Beast, Animaniacs, Battle Golfer Yui, Battle Mania, or Trouble Shooter Vintage, no Battletoads & Double Dragon, Beyond Oasis, Bonanza Bros, Burning Force, Castle of Illusion, Castlevania Bloodlines, Comix Zone, Contra Hard Corps, Golden Axe III, Kid Chameleon, Langrisser 1 OR 2, Mega Man Wily Wars, Monster World IV, Panorama Cotton, Phantasy Star 2, 3, or 4, Rent A Hero, Shining Force, Snow Bros, Splatterhouse 2 or 3, Sunset Riders, TMNT Tournament Fighters or Hyperstone Heist, Toejam & Earl, Valis, Valis 3, Vectorman, or either X-Men Game. AND YOU DIDN'T EVEN INCLUDE GUNSTAR HEROES. But yet you put BOTH Ecco The Dolphin games on here. My guy, you have some very terrible, and objectively bad and wrong opinions about the Sega Genesis and you need to fix that, now.
