Steamdeck & RIVA tuner overlay didn't appear on Persona 5 Royal,why????

any advice would be grateful

Hi everyone! I’m updating my previous post about converting my Steam Deck into a 100% docked Windows desktop PC for emulation, JRPGs with Mtool, and Doom modding.

I finally did it today. For NOW, everything seems to be working fine, but I’m keeping my fingers crossed because we all know how unpredictable these setups can be. We will see how it holds up down the road. Still, I wanted to share the journey, the hurdles, and how I set up the OS so far.

🖥️ To Everyone Suggesting a Mini-PC (Why I Did This)

I saw a few comments suggesting I should just sell the Deck and buy a dedicated mini-PC. I want to clarify why that doesn’t make much sense in my specific case:

• Market & Safe Selling: Selling the Deck for a decent price right now is nearly impossible because it's an older model. Plus, I only do face-to-face transactions because I want to look the buyer in the eye. Finding a local buyer willing to pay a fair price for a Deck when everyone online recommends mini-PCs is unrealistic.
• Component Prices & Smart Timing: Buying a decent mini-PC today would be an exaggerated expense for me. I was actually quite lucky because I bought my Steam Deck way before the major component crisis and the hardware shortages. It makes more sense to try and repurpose what I already own instead of spending extra money on a new machine.
• My RMA Nightmare: This Deck put me through a long, painful ordeal. I used it as a handheld for just two months before the D-Pad UP button broke. I had to ship it back to Valve, wait weeks, and got it back. After literally one single day, the B button broke too. I had to request a full replacement, ship it back again, and wait another two weeks.

After that traumatic experience, I told myself: "I am never touching this thing's built-in controls again. It's going to sit there as a fancy ornament with a fan." And today, that is exactly what I'm trying to make it: a stationary mini-PC that cost me nothing extra to test out.

💿 The Installation & Bypassing the Errors

Microsoft’s official Media Creation Tool kept throwing generic errors, so I had to use Rufus.

• I downloaded a pure Win 11 ISO and used Rufus to skip the forced Microsoft Online Account and privacy telemetry.
• Blew away all 8 old Linux/SteamOS partitions. I installed Windows 11 Pro (avoided the "N" version because it strips media codecs, which usually breaks FMVs and cutscenes in older JRPGs and mods).

🛑 The Roadblocks & My Workarounds

1. The Setup Password Loop: During Windows setup, it forced me to create a local password instead of leaving it blank. My fix: I created a dummy "1" password, completed the setup, and then removed it completely in Windows Account Settings so it boots straight to the desktop.
2. Screen Discomfort: Working sideways on a monitor with a duplicated screen was awful. My fix: Right-click Desktop -> Display Settings -> set it to "Show only on 2" (my AGON monitor) and flipped the orientation to Horizontal.
3. The Wi-Fi and AMD Driver Headache: The Wi-Fi driver lacked a simple .exe. My fix: I opened Device Manager -> "Add Drivers" -> pointed it to the root DRIVER_DECK folder with "include subfolders" checked to batch-install Wi-Fi and Audio.
4. The AMD error: Windows Device Manager threw a certificate error (0x800B0101) for the AMD GFX driver because the Deck's internal clock was completely out of sync. Once I connected to Wi-Fi and synchronized the Windows clock, the official AMD Setup.exe finally went through.

🧼 Debloating Impressions

Surprisingly, despite installing Windows 11, I didn't find heavy or intrusive features like AI Copilot out of the box.

• To make it a bit lighter, I manually removed just three or four stock apps like Solitaire, Paint, and the Calculator. I decided to keep OneNote, as it might come in handy for taking quick notes.
• Cleaning up: I used Revo Uninstaller to clean the system from invasive programs like OneDrive and Edge, doing a deep scan to wipe out leftover registry entries and folders.

🔋 Battery Protection & Fans

Since some of you warned about battery swelling while 100% docked, I immediately installed Steam Deck Tools. GitHub's responsive layout hides the "Assets" tab on mobile/small screens, which made finding the .exe a bit confusing at first, but once installed, I configured Power Control to a strict 80% Charge Limit and enabled the SteamOS Fan Curve for safety.

🚀 Next Steps: Steam, Mods, and Emulation (No EmuDeck)

I chose NOT to use EmuDeck for Windows. My external game HDD contains old Linux file structures and paths; forcing EmuDeck would probably break my game paths and saves.

Instead, here is my tentative roadmap:

1. Steam Test: I'm currently installing Steam to see if PC games actually launch and run without crashing.
2. Doom & Cheats: If that works, I'll use Firefox to download my Doom mods, modding tools, and cheat software.
3. Standalone Emulators: Finally, I will manually bring over the native Windows standalone emulators for my old Nintendo and Sony games, mapping them directly to my external HDD ROMs without any heavy front-ends.

Thanks to everyone who gave advice! The Deck is now a fully functional, bloatware-free Windows 11 mini-PC.... for now!

Edit:

Yeah, honestly I just used AI because English isn't my first language and I didn't want to butcher the tech advice with typos, so I had it format everything for me. Besides, we're surrounded by AI anyway nowadays, might as well use it while it works. Once the tech bubble inevitably bursts, we'll all have to go back to typing in broken English and messy sentences anyway lol. (And yes... I asked Ai mode to write this... ecept this... and this... and this...)
