Some more details: I can see that the mount operation is still in progress when the menu is displayed as the contents of the cores ("Arcade", "Computer", etc...), need some time to "populate". That can be solved by entering / exiting them until contents are available, but the "config" folder contents can't be...

Hi everyone, I've configured my MiSTer to mount at startup almost all folders from my NAS. I like this type of setup because everything is stored at the same place on my NAS, and can be easily accessed, edited and backuped. Everything works fine except for the "config" folder, that seems to be mounted after the "menu" initializa...

Thanks for checking. I have the same MD5 checksum as yours.

I redownloaded the latest NES_20220326.rbf from GitHub and it's working now.

Maybe a corruption of some kind during my latest update (IIRC I used the automated script).

Just to report that Zanac seems consistently crashing after defeating the very 1st boss of the game (the single "eye" on the ground) with the NES_20220326.rbf core. I tried different settings, resettings settings to default, etc... with no success. Reverting the core to the previous one (NES_20220212.rbf) fixes the problem. Let me know if...

Actually the Game folder names when not on the Mister SD card is case sensitive. Thanks darksakul, but I think there's something else, because I can see the different files beeing loaded from the network folder, including the usually biggest crom0 which takes a few seconds. It ends with loading vroma0. The screen then blinks quickly (like if the N...

If that can help, I had the same problem (black screen after loading a NeoGeo game), and solved that by just moving my NeoGeo ROMs from my network folder to the MiSTer SD card (with exactly the same contents). Seems like either the NeoGeo core is sensitive to storage access times when loading a game, or that there are some interactions with the net...

Final point to the story: I checked the jerkyness again with my 59.53Hz SNES + OSSC (same method as described before, checking the heart counter twinkling in Dracula X)... and it's definitively jerky too (this time every 2.38s). I did not notice that at the time, it's less obvious to notice compared to the MiSTer on scrolling only (maybe because it...

So,that suprised me, but the 60Hz mod on a PAL SNES really does not yield in the same output frequency as a genuine NTSC model. OSSC reports 60.08Hz for the MiSTer as expected, but 59.53Hz when I plug my SNES. After googling for "59.53Hz + SNES", I discovered this was a known fact: https://videogameperfection.com/forums/topic/snes-losing-...

The 60Hz mod is just a single-wire change somewhere on the PCB, quite easy to do. It switches the SNES VDP from PAL (50Hz) to NTSC (60Hz or so), I'm pretty sure the video signal result is the same as a US or Japanese SNES. I observe the scrolling problems only when the SNES core is configured to 60Hz (well, 60.1Hz). If I change to PAL / 50Hz, no pr...

You say the actual SNES connected via OSSC works fine on your display despite the MiSTer does not? Also what model of SNES you have and what mods if any were done to your SNES console? Many SNES consoles need a Dejitter mod to display correctly as the SNES isn't putting out a proper NTSC/PAL spec video My SNES is a Euro model. Only mod is that it ...

Your MiSTer is being accurate to the original hardware. Yep, that's what I was saying too, and I think that's a good thing :) The frame drops here does not come from the MiSTer HDMI output, it's really that my QLED TV does not like the 60.1Hz and drops one frame every 13.9s (same MiSTer with same settings works perfectly on an HDMI Iiyama monitor).

Thanks for the advices here. PikWik, I also noticed that the reported refresh rate was not always the same depending on the core launch conditions. But even with a (good) reported 60.1Hz, the jerkyness is present. I also tried different desperate sequences (powering up TV while MiSTer already running, switching HDMI sources, etc...). Aberu, I tried...

Another option could be to fix my TV. Normal settings do not help (I've tried everything), but maybe there's something to do in the hidden service menus to make the TV more tolerant with 60.1Hz (this post gives me some hope: viewtopic.php?p=5491#p5491) ?

Also, I noticed that the first 2018 releases of the SNES core had a 59.9Hz output, but sadly, I can't launch any game with them (it's staying stuck on a black screen after loading a game). Will give a try at the NES cores...

My LG OLED55C7 used to have those issues with a few cores outputting at off-spec frame rates, but it was fixed with some firmware update during 2018. Amiga at ~50Hz was the worst offender, while SNES was always smooth. Yep, I confirm that the problem is related to my TV: connecting the MiSTer to an HDMI Iiyama monitor works perfectly without jerky...

So I've found an old Compaq monitor that I connected directly to the VGA output of the MiSTer. I only had to add "forced_scandoubler=1" in order to have a compliant frequency. And this definitively fixes the jerkyness issue. Picture quality is also very good - I'd almost like to keep the MiSTer connected to it :) I'll give another try wit...

Thanks Cyril. I had the same suspicion about the TV first. I played with the settings (I had "Gaming mode" enabled) with no success. Also, I have other devices connected to the same TV (a RetroPie and an OSSC), the scrolling is perfectly smooth with them. I did more tests this morning, I'll try to give as much details as possible: Hardwar...

As opposed to what I said, this is also happening with the NES core. I might be totally wrong here but this could be like caused by a slight difference in the real hardware display frequency and the HDMI one (causing some frames to be dropped to maintain sync ?). As I said, I also tried using the VGA output of the MiSTer, but connected to and OSSC ...

Hi all, I've noticed that games having perfect scrolling on real hardware are sometimes a bit jerky on the MiSTer FPGA SNES core. That can be noticed on Final Fansasy 5 world map or at the beginning of "Castlevania - Dracula X" : scroll the screen to the right or left continuously and you'll notice some hiccups (something like 1 frame eve...

Now that I'm experimenting other cores, the "Hide Overscan" option of the NES core is exactly what I was looking for. Ideally it could be refined (something like Crop Left, Crop Right, Crop Up and Crop Down), and be specified per-game (like in RetroArch).

Thanks for the reply hash2fpga :) My current undersanding so far (after reading MiSTer Wiki) is that using my OSSC instead of the built-in HDMI converter should not have a bad impact on lag / latency, as there's indeed an existing delay on MiSTer. I'll just build me a VGA to SCART cable and hook it to my OSSC that has a bit more controls on the HDM...

Hi all, I'm wondering if it could be possible to "zoom" the MiSTer HDMI display, in order to display in full-screen a smaller area of the core frame buffer ? For example, MSX 1 games are using a 256*192 pixel area to display things, but the MSX core outputs a bigger area with 240 lines. Which is normal: the extra lines are the "backg...
