[Showcase] Turned my CRT + Batocera setup into a real arcade with a coin door mod

Hey everyone, just wanted to share a quick mod I did to my low-res PC + Batocera setup.

I added a real arcade coin door to my rig, so now when I play MAME games, I drop a coin just like I would on a real cabinet. It’s such a small thing, but it completely changes the vibe.

Playing shmups on my Fujitsu FM Towns CRT with actual physical coins hitting the mechanism hits different. Even the sound of the coin dropping makes the experience feel way more authentic than just pressing a button.

Super happy with how it turned out!

P.S. My English isn’t great, so I used AI to help me write this post. If anything sounds off, please forgive me!

Dug out my old Sega Saturn today, still absolutely stunning after all these years

Just pulled my vintage Sega Saturn out of storage.

I’m genuinely amazed by how beautiful the artwork and visuals are on Saturn games even after all these years.

Been replaying two classics lately:

Samurai Shodown: Warriors Rage
Tengai Makyou: Daiyamondo Jigokuhen

The art style and overall atmosphere are absolutely timeless. Always a pleasure to fire up this legendary console again.

Just wanted to share my latest CRT pickup, and my first deep dive into the FM Towns ecosystem: a Fujitsu FMT-DP533, a 14" color monitor built in 1991, originally made for Fujitsu’s iconic FM Towns home computer line.

📺 The Unit

This is a Japanese domestic market model, with a JVC-built CRT tube inside — the build quality and picture quality have already blown me away:

14" 4:3 CRT, 100V (running on an isolation transformer)

Supports 15/24/31kHz signals, perfect for low-res retro gaming

Specs from the rear label: Part No. D12L-0001-0945, 90W, manufactured May 1991

Tuned for the FM Towns’ 24kHz modes, but syncs flawlessly with every 15kHz console/arcade resolution I’ve thrown at it.

🎮 The Setup & Experience

I’m running this with a Batocera low-res 15kHz setup, and the results are everything I’ve been chasing for years:

The JVC tube delivers warm, natural colors and stable scanlines — no harsh white balance, no weird color shifting, just that authentic 90s pixel look.

Sync is rock solid for 240p console games (SNES/Genesis) and 480i arcade titles alike. Getting the main menu locked in at 640x480@60Hz took a bit of trial and error (pro tip: don’t accidentally toggle 31kHz mode if you’re on a 15kHz setup 😅), but now graphics are perfectly centered with zero overscan.

Input lag is non-existent for my use case, and the lack of motion blur makes playing fast-paced fighters feel way more responsive than any LCD I’ve used.

I’m using a low-res retro PC with Batocera, connected to a Fujitsu triple-band CRT monitor, always running in 15kHz mode for retro gaming.

Here is my annoying problem:
I use Batocera’s built-in CRT adjustment tool to fine-tune the screen position and offset to my perfect setup.

When I quit games back to the Batocera main menu via hotkey, the screen will randomly lose sync and glitch out. It does not happen every time, but the frequency is quite high.

The only way to fix it is manually re-select the 15kHz mode option again, then the display can return to normal.

But every time I reload 15kHz mode, all my customized screen position settings get reset to default. I have to readjust the screen offset all over again.

Now it’s a vicious cycle:
Tweak screen position → random sync glitch after exiting game → reselect 15kHz → screen settings reset → adjust position again.

The default screen offset is barely acceptable for playing, but this loop is really awkward and breaks the immersive gaming experience.

Has anyone run into the exact same issue?
Is this caused by unstable video timing switching, unfixed display configuration, or compatibility with non-standard Fujitsu CRT?

I’m looking for a solution to permanently lock the screen position, fix the random sync loss, and avoid resetting 15kHz over and over.

Thanks a lot for any help!

Besides asking for help, I also attached some photos of my full setup and real in-game screenshots for everyone to enjoy.
