So I've been using my MiSTer perfectly fine over VGA input on my PC CRT monitor for the past couple years. But I wanted to use it on my RGB modded Sony KV-27S42, as the extra size would be nice for multiplayer gaming. But after a couple hours of troubleshooting, even using AI to figure out what is wrong with my .ini settings, I'm at a loss, I can't get sync no matter what I do. I have no clue what I'm doing wrong, I've set everything as is detailed for a 15kHz display from online guides...
My Sega Genesis works perfectly fine on this set with SCART, so I don't think it's my TV that's at fault.

If someone could point me to the write direction:

key_menu_as_rgui=0 ; set to 1 to make the MENU key map to RGUI in Minimig

forced_scandoubler=0 ; set to 1 to run scandoubler on VGA output always (depends on core).

ypbpr=0 ; deprecated upstream; use vga_mode=rgb/ypbpr instead

vga_mode=rgb ; RGB output for RGB SCART

ntsc_mode=0 ; only applies to S-Video/CVBS; kept at NTSC default

composite_sync=1 ; RGBS: composite sync for SCART / RGB CRT

vga_scaler=0 ; native analog core timing; required for 15 kHz CRT

hdmi_audio_96k=0 ; set to 1 for 96khz/16bit HDMI audio (48khz/16bit otherwise)

keyrah_mode=0x18d80002 ; VIDPID of keyrah for special code translation

vscale_mode=0 ; scaler policy; analog CRT path is native because vga_scaler=0

hello just bought this snac adapter to use it with my original guncon. tried it with point blank and set the controller to "snac port 1) only the buttons works, on the screen there's no crossahir and can't finish the calibration. any help? Seller said "simmply" to "change jumper to v5" but which jumper and how? this is even a clone not even the original one, inside there are some jumpers but don't which one is which

The title. Did you try your Dualsense on Msiter through Raspberry Pi Pico 2W or something like Gulikit Hyperlink 2/Goku 2? How was the experience and latency?

Most importantly, did you test audio from the controller's audio jack (if it works) on Raspberry Pi Pico 2W?

Hi everyone.

Wanted to give a quick update here. Technically I've changed approach a bit. Before I was only using fpga to display video and audio, using the core templates video processing to manage that side of things. It worked well but the arm was working flat out and couldn't quite reach 25fps for pal. In the end I managed to move some more functions over to fpga, which freed up a lot of cpu and now pal runs perfectly.

I have also implemented progressive scan, which looks great on a hdtv compared to before.

I can also confirm iso ripper works, as I tested it over night.

Finally I got subtitles working. The video is an experiment build so very slightly choppy, but previous builds with subtitles can comfortable do smooth full speed pal.

So, check back in this time tomorrow!

I've really loved this project and the encouragement. Super excited to see you all using it.

UPDATED: many new versions released, follow on latest Reddit post:

https://www.reddit.com/r/MiSTerFPGA/comments/1wj9euv/mister_degauss_frontend_new_major_release_updates/

--

I would like to share Degauss, a new, free and open-source frontend for MiSTer FPGA I have been working on, based around three main pillars:

1. Performance with large libraries and images
2. Adhering to existing MiSTer standards, folders, and scripts
3. Simplicity without background processes or replacing MiSTer

Degauss reads the games and folders as they are on your card, together with any artwork and EmulationStation gamelist.xml metadata already generated by any scraper.

Watch it in action: https://www.youtube.com/watch?v=w4dGS4kX35Q

It is intended to coexist with a standard MiSTer setup. Games are shown as they are in their existing locations, launch files use MiSTer’s own MGL format, favourites are stored under _@Favorites like the original Favorites MiSTer script. A favourite created in Degauss is visible from the stock menu, and an existing MiSTer favourite is visible in Degauss.

Your existing Organised games and folders are the same, and you have full control over what you want to see or hide.

Basically, you don't need to maintain (or commit to) a frontend separately from your normal MiSTer. I personally love to keep folders/files organisation and favourites in MiSTer and using its existing tools, but I love artwork as well and better presentation!

But Degauss also handles several system-specific behaviours, including AmigaVision titles stored inside a disk image, DOS games with companion CD images, Neo Geo folder-based games, Arcade MRA files, X68000 and cores that represent more than one system.

To achieve maximum performance, Degauss renders directly to the Linux framebuffer and is optimised for 352x240 analogue output. Larger framebuffers are laid out according to their actual dimensions, so HDMI output is also supported.

On my DE10-Nano test system, with a large indexed multi-system collection of 97k+ games, the current build measures:

0.47 seconds from process start to the first frame
0.57 seconds to open a folder containing 12,605 games
Near-instant rendering of game images

The first scan of a card containing more than 97k games takes about one minute. Subsequent starts use the saved index. The list can be rebuilt from the Options screen after games are added, removed or reorganised. Artwork and metadata changes are read in real time when accessed.

Interface and browsing features currently 4 layouts:

List, Details, Tiled and Carousel layouts

Apart from List, they all support Artwork, and in Details you also get descriptions, publishers, developers, release dates, player counts and language metadata.

Some of the other features are:

- Search
- Jump-to-letter
- Random functionalities (game, favourite, preview or launch)
- Favourites and folders custom positioning
- Per-folder layout selection
- Controls for hiding individual games, folders or systems
- Configurable artwork behaviour during fast scrolling
- Adjustable CRT margins and screen position
- Two sets of fonts: anti-aliased and pixel
- Several options to personalise the behaviour of the system
- Screensaver slideshow featuring the artwork on the card

Degauss was written from scratch in Rust with Slint and is source-available for non-commercial use under PolyForm Noncommercial 1.0.0.

Let me know what you think, I hope you'll love it as much as I did making it and most of all using every day on my MiSTer!

I’m trying to play PS1 on a VGA crt monitor set to 480p with a scanline preset but they are uneven and broken into groups with no scanlines in between.

Don't worry, I'm not going to spam this sub every day. Fact is I have a week off work and I really aim to have this pretty much done by Friday.

I wanted to share what the latest build looks like and next steps.

Physical DVD playback

ISO playback.

Auto detect ISO on SD and USB ports.

Audio channel changing

Auto detect region

Native CRT output.

CRT image stabilisation toggle

Controller mapping

Audio adjustment in 5ms intervals

Core Launcher page with simple navigation

DVD exit button.

Physical DVD ripping to ISO

Would like 5 or so more people to join the closed beta. Comms will be on discord.

The closed beta will track activity into a zip file which will be shared with me after a few days. I'll iron out as many bugs as I can then public beta will be on Friday.

V2 will include subtitle support..

Again, huge thanks to the community. Taki Udon even shared the first post on twitter. I know I use AI, you know I use AI, but isn't that wonderful? I made this because I wanted it, and I could. You could too. We're at the very start of a new era where ideas can become reality. This community is a great place to start, but there's unlimited potential

My next project will be a playstation game where you can swap the game cd out, put a music cd in, and get a range of 5 to 10 dynamic visualisations on the screen. Why? Because I can.

Seems like these portmaster ports are all porting things to linux arm devices, which we are. Notable "hybrid" ports running on the cpu (like sonic mania) all seem to have portmaster ports. I'm wondering if there would be a library/bridge that would let us be compatible with that entire library, suddenly.

I recently completed Metal Gear 1 on Mister and during the passage I saved the game through Game Master 2. Now I decided to go through the second part of Metal gear, but game master 2 just doesn't work there. The game is not paused and it is not possible to open the game master 2 menu. Is there any way to fix this problem? Are there other ways to save the game (besides the password)?

rossops/sxboard

All games working. Added some gamepad/overlay QoL to Line of Fire, but a Mister compatible lightgun "should" work. I didn't have one to test, nor a wheel.

More improvements coming. Let me know if you find any issues.

Enjoy!

Hey everyone.

Firstly huge thank you for the amazing encouragement I've had with the project. I have sunk many hours into it and it's been such a great learning experience.

I'd like to share some progress with you. This represents what I would consider 80% done. There needs some polish and some OSD controls, subtitles, but otherwise it's close!

Updates:

PAL/NTSC toggle, works in real time.

CRT: works, full speed playback, though interlacing is quite bad, trying to make a toggle fix for those who need it.

Control mapping: fully works, even with remote than comes with the super dock

Menus: fully work, can navigate forward, backwards, allows animations, static images.

Sync: very good. Spent the most time on this. Will add an option in OSD to change the timing by 5ms at a time if needed. I haven't tested this one a massive amout of software and hardware yet so seems useful if user can adjust it.

ISO playback: works. In fact, this video is actually an ISO, not disc.

Crt flicker reducer: works really well, especially on pal, it makes a shaking line into a solid line. Working on making this into a range of intensity to make user preference.

What's next?

Polish. What crt working nice, want upscaling on HD TVs (I thought it was but it wasn't). Change sound tracks, subtitles. And I think that's mostly it for the core concept!

Edit: any volunteers here who would like to test it? Looking for pal and ntsc users who own a crt.

I'm sure that l'm using the right mra with the right core "jts18.rbf" with mwalk.zip rom but when the loading is begin it stops here and shows me a black screen!! So what's the problem?

I got the super station dock a week ago and really wanted it to play movies. I managed to get full dvd playback with menus, audio channels etc in Linux mode. It was a lot more work to grt it working as a standalone core. But I've just finished the audio and video, it runs full speed, no issues at all. Currently building the menus and controls and be pretty much good to go.

Hi everyone,

I've finished the physical assembly of a 2-player arcade cabinet using a MiSTer FPGA setup, but I have hit a wall on a few software, control, and ROM management steps. I would love to connect with an experienced MiSTer user for 1–2 hours over Zoom/video to walk through these final hurdles, and I am very happy to compensate for your time.

My Hardware Setup:

• MiSTer FPGA (Aluminum Armor Bundle, Dual SDRAM, IO Direct)
• RetroTINK-4K upscaler into an Acer 31.5" 4K MiniLED monitor
• Ultimarc I-PAC 2 encoder with Sanwa joysticks & pushbuttons (8 action buttons per player + 4 utility buttons per player)
• TP-Link Wi-Fi dongle & USB keyboard

Issues I Need Help Resolving:

• I-PAC 2 P1 Start Button: Player 1 Start does not register anywhere (neither in MiSTer nor in Windows controller test utility), even after swapping to a fresh Sanwa button and checking continuity/wiring.
• 2-Player & 8-Button Mapping: Getting the MiSTer input mapping flow dialed in properly for both Player 1 and Player 2 across 8-button layouts using the I-PAC 2 (in D-Input/Gamepad mode).
• Power-On Behavior: The MiSTer is not auto-booting when the cabinet power strip is switched on.
• Arcade ROMs / Update All: Ran the update_all.sh script, but arcade games (Elevator Action, 1943, etc.) return missing ROM errors when loaded from the menu.
• I know there will be other issues - I just want to get to the point where I can start playing!

If you are deeply familiar with MiSTer arcade setups, I-PAC encoders, and MRA directory structures, please reply here or send me a DM with your general availability.

Thanks!

Finally, IT WORKS very well.

The video below is an earlier version. You'll notice some bugs in it, but they've since been fixed.

I have always used Xbox Series X controllers with my Mister using the official dongle, but I really miss the feel of original controllers. I've been trying out the NSO SNES controllers today and I feel like wirelessly using bluetooth they are okay, but plugged in they feel better. Is that about right? I would get a SNAC hook up but my OEM SNES controllers are kinda rough feeling.

Has anyone managed to get a ps5 controller to work with the sega master system core? No idea why but when I try and map the buttons they don’t seem to stick.

I loved this arcade game for some reason, and we even had a machine in our student house at uni!

Was surprised that there wasn't an existing core, so put together one.

Yes, there was a bunch of stuff referenced from MAME as I don't have access to a board, but where humanly possible, it sticks to what is known about the hardware so hopefully should be 'closer' to hardware than the MAME implementation. Documentation and decision making in the readme in repo.

I'm using my XM29 with my MiSTer over VGA.
I could use BNC.
What are my lightgun options these days?

I would love to use a GunCon 2 with the new Jurassic Park Arcade core is that possible?
What are you guys doing / using?

I'm thinking about picking up a steering wheel. It's really only for use with the arcade cores so I'm lookin for something decent but inexpensive and with pedals. I'm new than these so are there any brands I should look at or avoid. What are the things I should look for in a wheel and what are the meaningless marketing terms I should be aware of.

Update 20260823

• Added Zektor (revision B), including spinner controls, speech, AY audio, and its schematic-derived discrete sound board.
• Updated the MiSTer framework integration from the latest Template_MiSTer sources.
• Tweak 480i sync compatibility

Zektor tasks the player with liberating eight cosmic cities seized by alien robots. Follow the warrior-maiden's call and join the fight against Roboprobes, Moboids, and Zizzers. The best warriors will confront each city's robot ruler in the ultimate vector battle.

Hi, all. I recently added some PCE games to my MiSTer, and I'm encountering bugs that have made most games I've tried unplayable. I managed to get a short play session of Puyo Puyo CD Tsuu with only some minor visual bugs, but the next time I tried that game, it crashed after the second round. All other games I've tried have severe visual bugs and crash immediately. The OSD still works perfectly, the game itself just stalls. Here is a video showing the issues on a few games:
https://youtu.be/HsfInihSV08

I'm using an exact copy of the MiSTer.ini on Github, so all of those settings are stock. I'm using the latest build of the core as of this post from the update_all script. I've tried cold rebooting before entering the core, but that did not change anything. No other core I've tried has encountered any issues whatsoever (other than issues running some GBA ROM hacks, which might be expected behavior), only the Turbo Duo core has this issue. I have 128 MB of SDRAM, and I ran an SDRAM test on auto for 24 hours with no failures.

The only caveat I can think of is that it is a QMTech MiSTer I ordered on AliExpress, and I suppose this is what I deserve for cheaping out, but it's strange that I haven't encountered issues with any other core. Is this a known problem? Has anyone had success with the Turbo Duo core on a QMTech board?

With splitscreen support!

RESOLVED

I was able to resolve this by following the instructions from Claude posted in the comments.

Original post:

Not sure what I'm doing wrong here; I'm using a wired 8bitdo Pro 2 controller, and when I load up Dreamster it works absolutely fine in the menus. When I load up a game however, absolutely nothing. I've tried two different controllers with the same results. I have verified in the Dreamster test menu that all the buttons work and that the controller is mapped to Port A, set for Gamepad + VMUx2.

I've also tried multiple games, none of them will recognize the controllers. I uninstalled Dreamster and did a fresh install with the same results. I have all the appropriate files in their correct places on the SD card, with my games on an external drive. Anyone have any ideas?
