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.

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.

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, psx, psp, dc, game-gear, master-system, genesis, sega-cd

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