 ===== Emulators =====
-==== Demul ====
+==== RetroArch ====
-From their FAQ:
+RetroArch has [[emulators:retroarch|its own page]].
->Demul is Sega's multi-system game console and automaton emulator, originally intended solely to emulate the Sega Dreamcast game console. Currently, the emulator also supports emulation of Sega Dreamcast-based slot machines: Naomi, Naomi 2 and Atomiswave . Support for Sega Model 3, Sega Hikaru, Sega Saturn is under development .
+=== libretro: Flycast ===
-Demul is run in Batocera under Wine, so any limitations that apply to Wine also applies to Demul (such as requiring ''ext4'' or more advanced filesystems, flaky controller compatibility and only working on x86_64). Demul also requires graphics cards with Vulkan support.
+A fork of a fork of a fork... this is an identical version of standalone Flycast but inside of a libretro core. Makes use of RetroArch's features.

 ===== Controls =====
-Currently controllers cannot be configured using the desktop app. This is a limitation of the Demul app under Wine. As of writing, only Player 1 is mapped with the default layout.
+Here are the default Naomi 2's controls shown on a [[:configure_a_controller|Batocera RetroPad]]:

-This part needs to be rewritten. It contains important information so it will remain here for now.
-Demul uses decimal for pad configuration in the padDemul.ini
+===== Troubleshooting =====
-To determine the decimal we have to convert the hexadecimal to decimal.
-You can edit arcade controls they're under the [JAMMAx_x] headings depending on the number of controllers.
-Controller 1 = 0x100 & 0x200 for the buttons & the 2x analog sticks.
+==== I cannot deactivate "Free Play" in some games ====
-Controller 2 = 0x101 & 0x201 etc.
-Device input hex codes are listed in the appropriate linux kernel input.h depending on the controller type.
+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.
-i.e. A gamepad's 'start' button is 0x13b
-Therefore controller 1's start button is 0100013b in hex or 16777531 in decimal.
-Controller 2 would be 0101013b / 16843067 accordingly.

-Here are the default Naomi 2's controls shown on a [[:configure_a_controller|Batocera RetroPad]]:
+Sadly, when setting “Free Play” to “OFF” in this Retroarch menu, the setting is //ignored// by most of the games.
-{{https://raw.githubusercontent.com/batocera-linux/batocera-controller-overlays/master/solid-4k/naomi2.png}}
+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":
-===== Troubleshooting =====
+  - 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.
