    Be sure to set your display to zero overscan for any of these recommendations. Both options will give you a 4:3 aspect ratio and crisp scanlines.

     

     

    The following settings will crop a small amount of pixels at the top and bottom, but I see nothing meaningful lost in any game I've played so far:

     

    Resolution: 1080p60

    Width: 1600

    Height: 1200

    Vertical position: 45

    Scaler: No scaler, enable both Horizontal and Vertical Interpolation

    Scanlines: Hybrid scanlines, set depth to taste (I use 50)

     

     

    The following settings provide pixel-perfect output with zero cropping, but you'll have empty space on all sides because the image won't fill the screen vertically:

     

    Resolution: 1080p60

    Width: 5x (1280)

    Height: 4x (960)

    Scaler: No scaler, Disable both horizontal and vertical interpolation

    Scanlines: Normal scanlines, depth to taste

     

     

    It also depends what you consider the "correct" aspect ratio for SNES games. My take is that we played the original console on 4:3 TVs, so even though the SNES's internal aspect ratio is 8:7, a CRT would've stretched it to 4:3 anyway, so 1280x960 provides a perfectly scaled image in a proper aspect ratio.

    I am using 1462x1200 @ 1080p60; SNES output of 224x256 displayed on a 4:3 display meant 8:7 pixel width:height, so at 5x scale, the width is multiplied by an additional 8/7 (256 x 5 x 8/7 = 1462). Disabled vertical interpolation because it's a clean multiple along the vertical axis.

    Upon first run, halfway through a first level of Super Mario World, my Samsung TV flashed to black for a second or two, and then back to the game. This usually occurs only when there's a changing resolution. I thought it was odd, but continued playing for a very long time, through various levels, other games (Mario Kart, Turrican DC, Mega Man X2) and the whole time this problem did not occur once more. Very odd how it only happened that once and (so far) never again. I wonder if others experienced that oddity. It was a one off event which didn't recur, and I hope doesn't recur again.

    I experienced the same thing with my Sony Bravia TV. I've experienced this before with the NT Mini and the Hi-Def NES too (only happens once each time you turn on the system, within the first minute).

    Okay this is just dumb. So I mentioned earlier that my package was in my home town (Shreveport, LA) on Saturday morning around 3am with a scheduled delivery on Tuesday. Well it's still arriving on time (presumably by end of day today), but I just looked at the updated tracking info. Apparently, the package left the Shreveport, LA facility, made it's way to Jackson, MS before turning around and sent back to Shreveport. I'd love to know the logistics of all this. I could have had my parcel Saturday if they were smart about it.

    Anyway I had to take a couple sick days off from work due to an unrelated but rather nasty sinus infection, but should be back in tomorrow. That will give me some time to play with my Super NT this afternoon, assuming they deliver it on time.

    Mine went from Vegas to Chicagoland without any scans in between and I still didn't receive mine until late this morning.

    I Upload now two videos, how good quality video ANALOGUE NT MINI producing, first we have composite video, compared to Twin Famicom.

    Please tell me what you think, later we compared more videos like S-video, component and RGB. I use latest Firmwares with Framemeister and Analogue NT Mini. This is my second console what I send back to Analogue and same problems is this new one.

     

    Fist video is here:

    Second is coming later... today

    Why are you taking the worst possible output from the NT Mini and passing it through a Framemeister when it outputs HDMI natively, since you are ultimately obtaining an HDMI signal anyways?

    For anyone in the USA wanting to track their Super NT order, go to the UPS website (not on a mobile browser) and track by reference. Populate shipment reference with your order number (e.g. #4694), including the pound sign, set shipment range start date to 02/06/2018 and end date today, your delivery zip code, and United States as the Destination Country. Leave shipper account blank. https://wwwapps.ups.com/WebTracking/track?loc=en_US

    For what it's worth, I ordered on 10/16 9:42AM (order #4694) and have zero clue when mine's arriving. No tracking info, no order status on the site, etc. The UPS my choice is flaky at best (keeps dropping me to the registration page after I registered). Ah well.. guess I just won't think about it and wait until it shows up.

    What is your delivery zip code? I can try to look it up for you.

    What is the most common use for an FPGA? I only know about them due to this project but are there some really well known uses? There must be something more common than what they are being used for here right?

    We use FPGAs in the trading industry for high-performance (low-latency) processing of inbound multicast market data and bidirectional TCP/IP order entry messaging.

    Thanks man!! I'm 'back in the game", haha...so I noticed the volume control for cartridge sound and the FDS/DISK (which is also enabled) seem to not be controlled by the volume adjustment. Do you have a recommended 'balanced' volume setting for the FDS sound?

    I don't have any recommendations on volume levels; perhaps Great Hierophant can offer his opinion as he has done extensive research on volume levels for the NT Mini.

    Oh - that's interesting...I'm running an FDS stick and Ram cart, and attempting to run Zelda, and the bonus sound isn't working.

     

    But I'm running Firmware 1.6, due to having issues with Video output for Atari 7800 on the latest firmwares beyond 1.7. Maybe that's the problem. I'm also running audio/video from the NT mini via analogue. Are you using via HDMI?

     

    Also I appear to be having an issue with the FDS stick switching disk sides...I thought I read FDS stick still had issues? Curious how you've gotten yours to work

     

    Thanks,

    I am using the latest jailbreak firmware. Make sure cartridge audio is enabled in Settings. I use both HDMI and component (both work fine). I did not have any of the earlier reported FDSStick issues. To switch to side B, press the button on the FDSStick twice relatively quickly (but not too fast). Press just once to flip back to side A.

    Hey all - anyone know if FDS audio support was fixed, or is that an outstanding issue/item? Is there a work around to get it to work on the Nt Mini?

     

    Thanks,

    There haven't been any NT Mini firmware updates since I discovered the broken FDS audio in Metroid (no sound opening doors). Since then I've bought an FDSStick and FDS Ram Adapter and that has been working perfectly on the NT Mini.

    The serial number issue shouldn't affect operation of any other aspect of the system.

     

    Per Analogue support:

    "This is minor issue that our software development department is now currently addressing. It does not cause any functionality problems, however there will be a firmware update coming out soon to rectify the typo."

    I hope the analog out would be as full featured as the NT Mini, (i.e. Composite, S-Video, Component, RGB). I'm not exactly sure how the NT Mini knows which signal to output. I assume it detects the cable or something? (correct me if I'm wrong). I wonder how this would work on an external DAC. Also, the RGB sync method is something controlled in the NT Mini menu, so I don't know if the DAC being external would complicate that.

    I believe the system first checks if HDMI is active. If not, it enables all analogue outputs simultaneously. If HDMI is being used and you turn off your TV, the system will fall back to producing analogue output (which is a problem when using an Everdrive but not the cores via SD card).

    Could somebody lend a hand with StarTropics? I'm on a Mac and I can't seem to find a bespoke tool for NES ROM header editing, so I've just been using a hex editor. I changed the submapper to 1 as suggested elsewhere in this thread by changing byte 8 from x00 to x01 and changing byte 7 from x00 to x08 (to designate the header as an NES 2.0 header). I tried loading this and the game runs but i get no music. Here's what i have in the hex editor:

    Am I getting my endianness wrong or something?

     

    Edit: I'm a dum dum. Just realized byte 8 should be x10 not x01. Hope this post helps somebody else

    Does the smokemonster Analogue NT Mini pack contain the ROM with the submapper already changed?

    I've heard many people have had this issue, hard to believe that it's a hardware issue affecting so many units. So far the console has been working great still running on stock firmware (both hdmi and component/composite tested to work as expected, works perfectly with my FDS RAM Adapter w/FDSStick). I sent an email to Analogue support.
