 ===== 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.
