Step 1: Transfer the Atmosphere files This folder contains the necessary system files to make the port run.
- Extract the downloaded GTA V files on your PC.
- On your Switch, open DBI in Full RAM Mode (hold the R button while launching any game).
- Select Run MTP responder and connect the Switch to your PC via USB cable.
- On your Windows PC, open "This PC" (or My Computer). You will see your Switch listed as a drive. Open it.
- Go into the folder named 6: SD Card.
- Drag and drop the atmosphere folder (from the extracted GTA V files) directly into the 6: SD Card drive. (If Windows asks to Merge folders or Replace files, click "Yes / Replace all").
Step 2: Install the Game (.NSP file)
- Still on your PC, click the "Back" arrow to return to the main list of the Switch MTP drives.
- Open the folder named 5: MicroSD install.
- Drag and drop the large game file (Grand Theft Auto V (homebrew port) [0100b00b51230000].nsp) into this folder.
- Wait for the installation bar on your Switch screen to reach 100%.
- Once it's done, press X on your Switch to close the MTP responder and unplug the cable.
Step 3: Overclocking (Mandatory) Since this is an unofficial, heavy port, the console needs maximum power to run it.
- Launch GTA V from the Switch home menu.
- As soon as it starts, open the Tesla Menu (press L + D-pad Down + Right Stick click).
- Go to sys-clk and max out all the values (CPU, GPU, and MEM to Maximum).
Step 4: Crucial Rules & Fixes
- Do NOT press the Video Capture button (the square button on the left Joy-Con) while playing. The game will crash instantly.
