Tico is the first custom emulation frontend for Nintendo Switch — a controller-first, native C++ interface designed for performance, simplicity, and long-term portability.

User guide

tico is a multi-platform emulation frontend focused on delivering a console-quality user experience.

Instead of file browsers, configuration menus, and fragmented tools, tico provides a unified interface that automatically organizes games, manages assets, and launches embedded emulator cores with zero user configuration.

It is designed to feel like a real console UI — not a development tool.

What tico does not include

tico does not include:

• ROMs
• BIOS files
• System firmware
• DRM circumvention tools

Users are responsible for legal ownership of games and compliance with local laws.

Features

Interface

• Redesigned UI with full dark mode
• Home screen with customizable game shortcuts and a dedicated favorites page
• Dynamic customizable cards — use custom images as console covers with swappable symbols and backgrounds
• Unified multi-console launcher
• Controller-first navigation
• Instant library loading with intelligent caching
• One-button rescan system
• Nintendo Switch account integration (avatar and nickname displayed in the interface)
• SteamGridDB integration — download cover art directly from the tico interface (API key required from steamgriddb.com)

Settings

• Comprehensive Settings screen with General, Display, Audio, Gamelist, and Emulator sections
• General settings: clock format (12-hour or 24-hour), ROM root directory picker with in-app folder navigation
• Per-core aspect ratio settings with unified display modes: 4:3, 16:9, Stretch, Integer 1×, and Integer 2×
• Per-core display configuration

Game Management

• Automatic No-Intro and Redump naming support
• Auto-organization by system and region
• Direct pinning from library to home screen
• Structured save and asset directories

Embedded and External Emulator Cores

• Built-in, statically linked cores
• External core support for flexible management, easier updates, and licensing compliance
• Resume app state support for external cores
• No manual installation
• No configuration required
• Optimized builds for Nintendo Switch

System

• Auto directory initialization — tico creates the complete folder structure for all supported consoles on first launch
• BIOS validation — tico checks for required BIOS files before launching a game and displays a clear error if any are missing

Architecture

• Written in modern C++
• Native performance
• No scripting languages
• No heavy frameworks
• Designed for long-term portability

Supported Systems

• Game Boy (GB)
• Game Boy Color (GBC)
• Game Boy Advance (GBA)
• Nintendo Entertainment System (NES)
• Super Nintendo Entertainment System (SNES)
• Nintendo 64 (N64)
• GameCube (GC)
• Wii
• PlayStation 1 (PS1)
• PlayStation Portable (PSP)
• Sega Dreamcast (DC)
• Sega Saturn
• Sega Game Gear
• Sega Master System
• Sega Mega Drive (Genesis)
• Sega CD

Installation

1. Copy the tico folder to the root of your SD card
2. Place tico.nro inside the switch folder
3. Launch any game while holding R to open the Homebrew Menu
4. Open tico
5. Install required cores via the in-app settings updater or manually from https://github.com/ticohq
6. Enjoy

Note: On first launch, tico auto-generates its full directory structure. After opening tico once, reconnect your Switch to a PC or phone to copy ROMs, saves, and BIOS files into the correct locations.

Important: tico does not work in applet mode.

Important (0.6.0): Cores are no longer bundled with tico. Systems will not run until the required cores are installed. Cores can be installed from the in-app settings updater or manually via https://github.com/ticohq.

Migrating from earlier versions

The project directory has been renamed from tiicu to tico. Existing users must:

1. Navigate to the root of the SD card
2. Rename the tiicu folder to tico
3. Move custom assets: sdmc:/tiicu/covers → sdmc:/tico/assets/covers and sdmc:/tiicu/backgrounds → sdmc:/tico/assets/backgrounds

All ROMs, saves, states, and configuration will remain intact.

Note: If you have a custom ROM path set via the old custom_roms_path field in roms.json, migrate your path through the new Settings interface — that field is deprecated and will be ignored.

Directory Structure

ROMs should be organized in the following structure:

sdmc:/tico/roms/{console}/
sdmc:/tico/assets/covers/{console}/
sdmc:/tico/assets/backgrounds/{console}/
sdmc:/tico/saves/{console}/
sdmc:/tico/states/{console}/

Where {console} can be: gb, gbc, gba, nes, snes, n64, gc, wii, psx, psp, dc, saturn, game-gear, master-system, genesis, sega-cd

ROMs can be organized into subfolders one level deep (e.g. psx/Resident Evil 2 (Disc 1)/).

Artwork must match ROM names (without extension) and must be in JPG format.

Custom ROM Path

You can set a custom ROM root directory through the built-in Settings screen under General Settings. Use the in-app folder navigation to select your preferred ROM root directory.

Note: Changing the ROM root path invalidates existing caches; a one-time rescan will be required.

Inside your custom path, keep consoles separated in their respective folders.
