Multi-Disc Games
This is a feature coming in next tico update (0.5.0) tico supports multi-disc games for select disc-based consoles. This page covers which consoles are supported, how to name your files correctly, and how to swap discs both from the launcher and mid-game. Supported Consoles Multi-disc functionality is automatically enabled for the following consoles: Console Folder PlayStation (PSX) sdmc:/tico/roms/psx/ Sega CD sdmc:/tico/roms/sega-cd/ File Naming Convention For tico to detect a game as multi-disc, all disc files must share the same base name and include a disc number in one of the following formats (case-insensitive): (Disc 1) ... (Disc X) (Disk 1)... (Disk X) (CD 1)... (CD X) Example — PlayStation: sdmc:/tico/roms/psx/Final Fantasy VII (Disc 1).chd sdmc:/tico/roms/psx/Final Fantasy VII (Disc 2).chd sdmc:/tico/roms/psx/Final Fantasy VII (Disc 3).chd Example — Sega Saturn: sdmc:/tico/roms/saturn/Panzer Dragoon Saga (Disc 1).cue sdmc:/tico/roms/saturn/Panzer Dragoon Saga (Disc 2).cue sdmc:/tico/roms/saturn/Panzer Dragoon Saga (Disc 3).cue sdmc:/tico/roms/saturn/Panzer Dragoon Saga (Disc 4).cue tico scans up to 10 consecutive discs automatically. Folder Support tico supports placing multi-disc games inside subfolders, and can locate linked discs even across different folder locations. The system uses a two-step search: 1. Strict Path Replacement (Fast) If Disc 1 is at psx/RPG/Game (Disc 1).cue, tico first tries replacing the disc number in the same path, checking immediately for psx/RPG/Game (Disc 2).cue. If your discs are neatly co-located, this resolves instantly. 2. Recursive Filename Fallback (Robust) If the strict replacement fails — for example, Disc 1 is inside its own subfolder but Disc 2 sits in the console root — tico extracts just the filename and recursively scans the entire console folder to find it. This means all three layouts work automatically: Layout Example Flat psx/Game (Disc 1).cue → finds psx/Game (Disc 2).cue Subfolder psx/MyGame/Game (Disc 1).cue → finds psx/MyGame/Game (Disc 2).cue Mismatched psx/Game (Disc 1)/Game (Disc 1).cue → finds Game (Disc 2).cue anywhere in psx/ Cross-Extension Support The fallback search ignores file extensions, so you can mix disc formats within the same game. Booting Game (Disc 1).chd and swapping to Game (Disc 2).cue or Game (Disc 3).iso works seamlessly. If multiple matching formats exist in the same folder, tico uses an internal priority ranking to pick the best option: .m3u > .cue > .chd > .iso > .bin Launching a Specific Disc When you select a multi-disc game from either the Home Screen (desktop shortcuts) or the Launcher Screen (game list view), an additional prompt appears in the bottom control helpers bar. X — Change Disc Press the X button on your Joy-Con (or its mapped equivalent on PC) to open the Select Disc Modal. This lists all detected discs for that game (e.g., Disc 1, Disc 2, Disc 3). Selecting a disc launches the emulator directly with that disc file. This is useful if your save file is already on Disc 2 and you want to skip Disc 1 entirely. Swapping Discs Mid-Game Many multi-disc games will prompt you to insert a new disc partway through. When this happens, you can hot-swap discs from the Quick Menu without losing your progress. Note on PSP games: The PSP hardware did not support hot-swapping UMDs mid-game. Multi-disc PSP titles (e.g. Final Fantasy Type-0, Trails in the Sky SC) handle disc changes by prompting you to save at the end of Disc 1. You must then exit the emulator, launch the Disc 2 file from the tico dashboard, and load your save. The Change Disc option in the Quick Menu is intentionally disabled for PSP titles. How to hot-swap: Open the Quick Menu — Press + (Plus) on the Joy-Con. Access Disc Controls — Press X (Switch). The bottom helpers bar will display X Disc. Select the new disc — Pick the disc requested by the game from the Disc Select Modal. Resume — tico automatically ejects the virtual tray, swaps the disc image, and closes the tray. The game detects the new disc and continues. Notes All disc files for a game must be placed in the same console root folder — do not use subfolders. The base filename must be identical across all discs, with only the disc number differing. For multi-file formats (.cue/.bin, .gdi), all associated track files must be present in the same folder alongside the cuesheet. .chd is recommended for disc-based consoles — it combines all tracks into a single file, simplifying multi-disc organization and reducing storage use. Compressed archives (.zip, .7z) are not supported — all disc images must be uncompressed. tico scans up to 10 discs per game. Titles with more than 10 discs are not supported.

Supported ROM Formats
tico supports the following ROM formats for each console. Make sure your files use one of the listed extensions and are placed in the console's root folder or up to one subfolder deep — for example, sdmc:/tico/roms/psx/ or sdmc:/tico/roms/psx/My Game/. Nintendo Entertainment System Folder: sdmc:/tico/roms/nes/ .nes .unf / .unif .fds (Famicom Disk System) Super Nintendo Entertainment System Folder: sdmc:/tico/roms/snes/ .sfc / .smc .fig/ .swc .bs/ .st Game Boy Folder: sdmc:/tico/roms/gb/ .gb Game Boy Color Folder: sdmc:/tico/roms/gbc/ .gbc Game Boy Advance Folder: sdmc:/tico/roms/gba/ .gba .sgb Sega Master System Folder: sdmc:/tico/roms/master-system/ .sms/ .bin Sega Game Gear Folder: sdmc:/tico/roms/game-gear/ .gg / bin Sega Genesis / Mega Drive Folder: sdmc:/tico/roms/genesis/ .md / .gen / .bin .smd Sega CD Folder: sdmc:/tico/roms/sega-cd/ .cue + .bin (cuesheet + raw tracks) .iso / .chd Sega Saturn Folder: sdmc:/tico/roms/saturn/ .cue + .bin (cuesheet + raw tracks) .iso / .chd Sega Dreamcast Folder: sdmc:/tico/roms/dc/ .chd (recommended) .cdi .gdi + associated track files .cue + .bin (cuesheet + raw tracks) PlayStation (PSX) Folder: sdmc:/tico/roms/psx/ .chd (recommended) .cue + .bin (cuesheet + raw tracks) .iso PlayStation Portable (PSP) Folder: sdmc:/tico/roms/psp/ .iso .cso (compressed ISO) .pbp .chd Notes ROMs can be placed directly in the console's root folder or inside one subfolder (e.g. sdmc:/tico/roms/psx/My Game/game.chd). Deeper nesting is not supported. Compressed archives (.zip, .7z) are not supported — ROMs must be uncompressed. For multi-file formats (.cue/.bin, .gdi), all associated files must be placed in the same folder. .chd is recommended for disc-based consoles — it reduces file size and keeps everything in a single file.

BIOS Setup
Some consoles require a BIOS file to run. Place the BIOS files directly in the console's system folder — for example, sdmc:/tico/system/psx/. PlayStation (PSX) Folder: sdmc:/tico/system/psx/ One of the following: scph5501.bin (recommended, USA) scph5502.bin (Europe) scph5500.bin (Japan) scph1001.bin Dreamcast Folder: sdmc:/tico/system/dc/ dc_boot.bin (required) Sega Saturn Folder: sdmc:/tico/system/saturn/ One of the following: saturn_bios.bin sega_101.bin mpr-17933.bin Sega CD Folder: sdmc:/tico/system/sega-cd/ One of the following depending on your region: bios_CD_U.bin (USA) bios_CD_E.bin (Europe) bios_CD_J.bin (Japan) Notes BIOS files must be placed directly in the console's system folder — do not create subfolders inside it. BIOS files are not provided by tico. You must obtain them from hardware you legally own. Consoles not listed here do not require a BIOS file. BIOS files are copyrighted by their respective manufacturers. tico does not distribute BIOS files and does not support obtaining them from unauthorized sources. You are solely responsible for ensuring you have the legal right to use any BIOS files you provide. By using tico, you agree to our License and Terms of Use.
