Fightcade allows you to play several games online, focus is fighting games, but Contra 3 is there, it uses Snes9x 1.60-2 core for SNES games.

Yes, I know, but I'm not very good, I still need to train more, my PB is 17 minutes and 46 seconds, it's well above average, but for my level I think it's a good time, in the future I'll train to achieve it without this technique.

Thanks for enlightening me.

This technique consists of constantly pausing the game, simulating slow motion, I use this on the Brain boss, as it helps to hit the sphere I want, I read the rules and didn't see anything about it, but I want to make sure if I can use it in a official run.

I'm new to the subject and I don't know English, I used the translator, if there is any error I apologize.
