Re: Would MiSTer ever be able to run a Neo Geo core?

Man, seems there is a huge price jump to go from a 256M chip to 512M (with the Alliance brand anyway, from ~$3.20 to over $10, and Digikey doesnt even have stock :) ). Is the concern of multiple chips the power draw it will place on the DE10? If not, would it be feasible (assuming matching trace len...

Re: Custom Video Modes Test Thread

Maybe but that looks like the old scanline effects and not a filter coefficient effect. Correct this is the Scandoubler FX option. I mostly use MiSTer through a CRT without the scaler so I'm not used to using the scaler options for scanlines. I did however set the scaler to Nearest Neighbor to get ...

Re: Custom Video Modes Test Thread

The settings are: video_mode=1920,48,32,112,1440,3,4,39,184828 This seems to work well on my 1440p monitor, which fortunately has a 1:1 pixel mode. You get a nice 7x6 integer scale on the SNES core.

Re: Custom Video Modes Test Thread

I didn't want to post this in the scaler thread since that is supposed to be for the devs, but some people in there were asking about 1440p video modes. I personally had success making a 4:3 1440p (1920x1440) custom video mode. The settings are: video_mode=1920,48,32,112,1440,3,4,39,184828 I tested...

Re: Newbie questions

Is it possible to add a feature so you can set a default folder for each core, for example the NES core you can set the default folder for where the roms are so each time you load a game it will automatically open up at that folder? MiSTer already does this, but the folder names are hardcoded. For ...

Re: Autosave and shutdown

Adding this option as standard will give false assumption MiSTer requires a special procedure to shutdown which is untrue. You are absolutely correct - it is strictly a user experience thing over any actual technical need. But I think there are products that exist in which the designers had to take...

Re: MISTer Ethernet (not so) strange behaviour

Sefirosu deserves the credit here of course. I just validated the solution was correct.

Sorgelig, I believe we have the fix for this now. Please see my post, and Sefirosu's post above.

Re: I/O Board

I don't think it is the job of the equipment downstream to apply filtering to the SPDIF signal, it should income "ready" for reproduction, aa filtering already applied. Agree with this statement fully. Would it make sense to apply all filtering early enough in the signal chain (using an a...

Re: I/O Board

i hear the difference, but it's unclear if sound go through the same route or not. Maybe something outside of MiSTer distorts it. These were recorded using the same device digitally - an M-Audio MT2496 which has a coaxial SPDIF input. HDMI audio was captured using a device that breaks the digital a...

Re: I/O Board

SPDIF uses different kind of filter than I2S(HDMI) I'm curious (and probably JamesF as well) why there is any difference in the data between HDMI/I2S and SPDIF? In theory, can they not be the same datastream, just presented differently depending on the output? My apologies if it sounds like a dumb ...

TOSLink doesn't need too high brightness. I use random non-name red LED for TOSLink. I don't think it's brighter than 100mcd. Sorgelig's specs do indicate a low mcd diode indeed (per WIKI https://lcsc.com/product-detail/Light-Emitting-Diodes-LED_f3Long-legs-Round-with-edge-Red_C2155.html - which BT...

Re: I/O Board

So the question is, are there any dangers here for using these generic no-spec LEDs. I really don't want to damage my DE10. Please forgive my ignorance and thank you for your time. I have found that most generic 3mm/5mm LEDs are similar in specs. I'm not an expert in LEDs but I believe the current ...

Re: Local Sellers for MiSTer Expansion Boards

Wrong CAPS. They are 100nF or 0.1uF In the SDRAM thread, other builders had better luck with 1uf versus .1uf with the Winbond chips (Sorgelig himself made this suggestion). My understanding is C1-C6 are for noise filtering on the VCC line (The Winbonds are apparently a little more sensitive to VCC ...

Re: MiSTer NES Core

The IO Board will be outputting 3.3 Volt "TTL" for sync on VGA port pins 13 and 14. It does have a resistor in series, IIRC, but it's still recommended to add an extra resistor of say 680 Ohms in series from pin 13 to Csync on your monitor / TV. (so a 680R resistor between VGA pin 13 to p...
