====== 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. ==== Quick reference ==== * **Emulators:** [[#retroarch|RetroArch]] (default), [[#mame|MAME]], [[#demul|Demul]] * **Cores available:** [[#libretro:_mame|libretro: MAME]] (default), [[#mame_2|MAME (standalone)]], [[#demul_2|Demul]] * **Folder:** ''/userdata/roms/gaelco'' * **Accepted ROM formats:** ''.zip'', ''.7z'' ===== 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. 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. Your graphics card requires **Vulkan drivers** for Demul to work. === 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. ===== Troubleshooting ===== For further troubleshooting, refer to the [[:support|generic support pages]].
