This is a common problem for arcade emulation, so you maybe want to read and understand how that works first, from https://retropie.org.uk/docs/Arcade/.
If the ROM doesn't work, then you'll need to find the correct ROMset version for your emulator and get the ROM from that collection version.

i itried it yesterday and it seems to work.
I deleted the entry in "Insert Coin Player2".
So if i want to play with a friend i just insert 2 coins with my Player-1 Pad or Arcade-Stick.

On the Display the following message appears: "Press 1 or 2 Player Start".
If you press the 2nd Player-Start-Button both players are in the game.
But as only Player1 can insert coins the 2nd Player cannot continue ;)

@sirhenrythe5th I like the way you think. I am going to try this.

Check 1941 for the SuperGrafx, one of the 6 only games released for the console. Gameplay is updated with charged shots, but same in essence. You will love the music, it’s got that distinctive TurboGrafx flavour with bright chip tunes.
