I would recommend playing the game somewhere that has a rewind function or save states which I think the NES Online has? I’m not sure but if you want to actually just have fun with the games I recommend that. If save states aren’t on NES Online I would go with 3DS if they’re on there. I honestly can’t remember if they were ever ported there or not. But yeah, the games are hard so if you just want to play to enjoy them do that.
Also, if the idea that the game “laughed at you” for going into Ninja Dog on NG Black or Sigma. I would recommend going back to it in hindsight and just accepting the little jabs as a bit of fun. The easy mode, as pointed out by

** how you play? Play the way you want to and if you want the game to be easier? Do it! I support every step of the way as long as you’re enjoying the games. If not? Put the controller down and walk away from that game forever. No hard feelings! I’m not gonna give you ** because I’m happy as hell you gave it a second chance; if you so choose.
If I had to recommend anything, I would wait till early next year to see if that Sigma Trilogy is legit so you can snag them there. Glad you’re going to at least give the NES games a shot though. Enjoy dude!
