Troubleshooting
I cannot deactivate "Free Play" in some games
Emulationstation as of v41 (and current v42_beta) has no switch to deactivate “Free Play” on the NAOMI and NAOMI 2 systems. You have to use Retroarch core settings according to the Wiki, see https://wiki.batocera.org/advanced_retroarch_settings.
Sadly, when setting “Free Play” to “OFF” in this Retroarch menu, the setting is ignored by most of the games.
To get this setting accepted, you have to access the “System Menu” of the NAOMI game in question and set “COIN/CREDIT SETTING” to “# 1”:
- Enter the Retroarch menu (when in game, Hotkey + South).
- Go to “Core Options” → “System”
- Set “Allow Arcade Service Buttons” to “ON” and “Set NAOMI Games to Free Play” to “OFF”
- Exit the Retroarch menu using “Restart”.
- When in game, press “L3” to enter the System Menu of the game. “R3” is used to navigate this menu, “L3” to select an entry.
- Navigate this way to “COIN ASSIGNMENTS”
- Set “COIN/CREDIT SETTING” to “# 1”.
- Exit the System Menu by selecting “EXIT” twice.
- Optionally you can now set “Allow Arcade Service Buttons” to “OFF” to prevent accidental entering of the game's system menu.
If “COIN/CREDIT SETTING” is set to “# 1”, the game in question will respect the Retroarch setting for “Free Play”, even if you set “Free Play” to “ON” in Retroarch again.
