Introduction

Custom Firmware (CFW) refers to a modified or alternative operating system installed on a device. It adds features like improved emulator support, performance tweaks, and custom themes. Most CFWs are based on Linux, offering flexibility and open-source support. Installing CFW usually involves flashing a microSD card and booting from it.

It creates a bootable drive. ℹ️ Info The "flashing" process is basically the same for all firmwares, but there may be some additional steps to get it working for your specific device. ↪ Firmware Flashing Guide Choosing the right micro SD card Lots of devices come with cheap quality micro SD cards. If you don't want to risk loosing your 50 hour Pokemon save due to file corruption, it's recommended to get a card of a known brand. Recommended SD card sizes The firmwares usually take around 5GB-12GB of space. The card size(s) depend on your game list. This is only a reference point for smaller curated game lists up to PS1. 1 card Setup: 128GB 2 card Setup: TF1: 16-32GB TF2: 64-128GB DTBVault DTBVault DTBVault is a community-driven archive for .dtb files, which are needed to boot. This archive is useful if you need to obtain a .dtb file that was corrupted in your handheld. ⚠️ Warning Wrong .dtb files can cause damage to your handheld, usually caused by overvolting critical parts. ℹ️ Info If you can, please upload .dtb files that have not yet been uploaded.
