I won't go in detail as to how to create cheat codes as there are many guides around the internet and this was also my first time doing so (i.e. Since we can no longer insert coins, I created a cheat file for the game to be permanently set on 99 credits. You may create it manually in that folder, with that name.ģ) Create/load a cheat code for infinite credits In my case, this created a /opt/retropie/configs/arcade/FinalBurn Neo/snowbro2.rmpfile with the following: input_player1_btn_select = '-1' Since the problem relates to inserting coins, start by removing the COIN button mapping from select, for P1 and P2, and save a Game Controls override file. This will be used at the last step, but it's easier to create it before the next steps.Ģ) Remap controls to remove the 'coin' button mapping In my case, it had created a snowbro2.state1 file, so I renamed that to. Now, navigate to your arcade roms folder via SSH, command-line or in any other file explorer and rename that most recent save state to. Note the name of the save state in the RetroArch dialog on the bottom left corner of the screen. Start by launching the game as normal, and after the 'HELLO' launch prompt disappears create a save state by pressing HOTKEY + R1. Set the game to auto-load a save state on launch Īlso, my workaround is on lr-fbneo with the ROM snowbro2.zip, so I recommend using this emulator and this exact ROM (and not a clone) if you apply the exact same changes.ġ) Create a save state after the initial boot stage.Create/load a cheat code for infinite credits.Remap controls to remove the 'coin' button mapping.Create a save state after the initial boot stage (to be used in step 4).The different pieces for my workaround in this case are: Workaround: Since this game quickly became one of the favorites of the kids to play together with me, since it supports more than 2 players, I looked for fixes for a while - different emulators, even latest MAME releases, but nothing, so I had to come up with a workaround. Scenario: Playing with multiple players (the game supports up to 4 players), when it's time to insert credits to continue halfway through the game (young kids, especially), a slight delay in releasing the coin button will result in the game hanging.

The high-level approach for the workaround can be applied.

It also happens for other games (a quick Google Search shows that) but this does not fix those. Symptom: Snow Bros 2 hangs with 'Coin Error' if a coin button is held for two long. Just sharing a hacky workaround for the Snow Bros 2 'Coin Error' that happens if you hold the coin button for a bit too long.
