 +====== Gaelco 3D ======
 +
 +The Gaelco 3D is an arcade system board created by the Spanish company [[https://en.wikipedia.org/wiki/Gaelco|Gaelco]]. The PowerVR 2-based variant used similar technology to Sega's [[systems:naomi|NAOMI]] hardware, featuring two Hitachi SH-4 CPUs and a dedicated NEC PowerVR Series2 GPU. The system produced a small library of driving and sports games between 1999 and 2003.
 +
 +This system is only available on **x86_64** builds.

 +===== BIOS =====
 +
 +No BIOS files are required.
 +
 +===== ROMs =====
 +
 +Place your Gaelco ROMs in ''/userdata/roms/gaelco''.
 +
 +ROMs should be in zipped format compatible with **MAME 0.284** or later.
 +
 +<WRAP center round important>
 +The emulators are still work in progress for Gaelco games, so mileage will vary. Performance depends on your x86_64 system hardware. If you get audio stuttering and slow music, your system is not powerful enough to run this system.

 +
 +===== Emulators =====
 +
 +==== RetroArch ====
 +
 +[[https://docs.libretro.com/|RetroArch]] with the **libretro: MAME** core is the **default emulator** for Gaelco in Batocera.
 +
 +=== RetroArch configuration ===
 +
 +RetroArch offers a **Quick Menu** accessed by pressing ''[HOTKEY]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} which can be used to alter various things like [[:advanced_retroarch_settings|RetroArch and core options]], and [[:remapping_controls_per_emulator|controller mapping]].
 +
 +==== MAME ====
 +
 +[[https://www.mamedev.org/|MAME]] (standalone) can be used as an alternative emulator for Gaelco games. It supports the full Gaelco ROM set.
 +
 +==== Demul ====
 +
 +[[https://demul.emulation64.com/|Demul]] is a Sega Dreamcast and arcade emulator running under WINE.
 +
 +<WRAP center round important>
 +Your graphics card requires **Vulkan drivers** for Demul to work.
 +</WRAP>
 +
 +=== Demul: First start ===
 +
 +You need to run a ROM at least once **and** be connected to the internet. This creates the directory structure and installs the associated Windows libraries for WINE.
 +
 +It may take some minutes before the game starts on first use — this is normal. Please be patient as it can take up to 2 minutes depending on your internet connection speed.
 +
 +=== Demul: Controllers ===
 +
 +Currently controllers cannot be configured using the desktop app. This is a limitation of the Demul app under WINE but also a known buggy pad plugin, even under Windows. Currently 2 players are mapped using the emulator's default keyboard configuration via evmapy.
 +
 +=== Demul: Service Menu ===
 +
 +A keyboard is required. You can access the Service Menu using **F4** and then use **F2** to navigate with **F4** to select.
 +
 +=== Demul configuration ===
 +
 +^ ES setting name ''batocera.conf key'' ^ Description >> ES option ''key value'' ^
 +| **GAME ASPECT RATIO ''gaelco.demulRatio''** | Set the game aspect ratio.\\ >> Stretch ''0'', 4:3 (Default) ''1'', 16:9 ''2''. |
 +| **VSYNC ''gaelco.demulVSync''** | Fix screen tearing.\\ >> Off ''0'', On ''1''. |
 +| **SET GAELCO SCALING AMOUNT ''gaelco.demulScaling''** | Set the amount of scaling from Gaelco's original resolution.\\ >> 1x ''1'', 2x ''2'', 3x ''3'', 4x ''4'', 5x ''5'', 6x ''6''. |
 +
 +=== Demul: Compatible ROMs ===
 +
 +Demul has a specific list of currently compatible ROMs:
 +
 +^ ROM name ^ Game title ^
 +| ''atvtrack'' | ATV Track (set 1) |
 +| ''atvtracka'' | ATV Track (set 2) |
 +| ''gfootbal'' | Gaelco Football |
 +| ''smashdrv'' | Smashing Drive (World) |
 +| ''smashdrvb'' | Smashing Drive (UK) |
 +| ''smashdrvs'' | Smashing Drive (Spain, Portugal) |
 +
 +With both MAME and Demul you should be able to play the full collection of games.
