MiSTer FPGA Forum

Received my mister pi this previous Monday via DHL. Haven't been and to test it out yet though.

I am still waiting for my tracking code

Received the 2nd batch, encountered a problem where GBA core output garbled crackle audio (no music just sounds)
most other core sounds ok as of now for initial testing.

Do you get the GBA splash screen?

Does it need a BIOS? Do you have BIOS options enabled for update_all?

Still waiting on mine. I just verified it works on my MiSTer, if nobody else does it by the time I get it I’ll put this SD in my MiSTer Pi and see if there’s any issues.

Splashscreen ok games loads ok, just that audio is some stuttering noise and not music.

This SD card is pulled directly from my DE10 nano Mister which I've been using since 2018, it still works fine with the original unit, no issue with anything at all.

I tried the original SD card and a new SD with all the files copied over still having same issue with the GBA core.

Seems like audio issues are quite common with the clone boards

I thought the audio issues were supposed to be sorted with the new batch. Maybe you could ask Taki directly?

Those mentioned in that few threads was sorted, but GBA core is new issue, and its still audio related
Already sent an email, waiting for their responses, in the meantime giving you guys a heads up so see if anyone also running into the same issue.

Unfullfilled so far

have we ruled out a BIOS problem with the garbled audio issue? people have been testing these for a while now, and i think something like this would get mentioned pretty quick. or is this specific to the 2nd batch?

are you sure everything on the mister pi is plugged in/seated all the way? i had some strange issues on my de-10 with the SNAC port, but after replugging everything in a couple times, my controllers worked again.

but for the GBA core, i also remember having to find a specific BIOS file for the GBA core, and rename it to boot.rom, because the generic one it kept trying to use was buggy

EDIT
ahh, i see now you tried your original working SD card in the mister pi from a working de-10.
thats so strange. if that is the case, i hope its a one off situation and Taki gets it sorted.

I found stranger stuffs while meddling with some settings, the video filter seems to meddle with the audio issues, still have cracking audio though.

anyway I uploaded the vid on gdrive

I got my shipping notice early this morning. I ordered on 11/19, (locally) the morning after the orders went live. Hopefully if you ordered before then, you have also now gotten your tracking info.

I didn't really need a second MiSTer, but I am going to have this one live in my arcade cabinet permanently so that my original can be mobile between several different screens. I won't need a handheld MiSTer either, but I'll almost certainly be getting one whenever those are available.

I ordered mine 6h after the release, and I still have no tracking number. Maybe it is being delayed because I ordered it with a blue case? (which I regret, I printed one at home and I like it more than the clear case)

Could be a geographical thing maybe, or maybe the difference in what we ordered - or really any number of reasons, really. I guess it’s not a safe assumption that they’ll ship based on order date. I ordered the $180 stack because that was all that was available at that time. I didn’t get anything else, so it was a pretty simple order.

Tracking number received. It only took 2 weeks.

Got mine in the UK yesterday.

Haven’t had a chance to test yet.

Yeah Australia here, got mine yesterday too.

Received mine today. It took 2 weeks and 2 days.
There is an snac adaptor but it is usb male / usb female, I wonder what it is for ?

It’s a level shifter to save damage to the board by diff voltages. You plug in both to the SNAC.

When I see people who are closed to the Raspberry Pi and defend their option tooth and nail, they don't let others play with the options they want.

And on top of that they have the Orange Pi 5, which for the same price, emulates more than the Raspberry Pi 5. The Raspberry Pi 5 cannot handle all the Nintendo 64 games. It still gets stuck in many Saturn games. And from dreamcast and game cube, only the least demanding ones, it emulates them

and I have also used the raspberry pi up to the pi 4 and I have had two misters and now I am going to buy the mister pi

and for the raspberry pi 5 if you add boxes, etc., at €200 or $200 it can cost you

It hurts that clones of the mister are already coming out and at the same price as the raspberry pi 5

Mine seems to be stuck in Grand Prairie for days with no movement

Not yet. I’m hoping it snuck through.

Might have discovered something off? about the analog output on the Mister Pi I/O boards. Not sure if its the board itself or the mezziane but I had the exact same behavior frankensteining those boards to a de-10 nano as the clone Mr. Pi board.

Using a 5A 4V power supply, standard analog output (240p) and scandoubled (480p) seemed to work fine. 1920x1080 using vga_scaler has proved unstable however, checking both with a VGA LCD and CRT. Sync on the menu would succeed or fail depending on which of ranny's wallpaper loaded. Even when synced properly, the brighter colors ripple/flicker on my LCD. Running the Genesis core I could trigger black screen by using the monochrome aperture grille (no scanlines) shadow mask (versus using the standard apeture grille mask, or using no mask.) These work fine on the old 5.2 I/O board, even up to 1920x1440p, and of course HDMI output up to 1440p has been fine on the Mr Pi. Played the Pi a bit with 1280x1024 VGA output and that seemed more stable in spite of being nearly as many lines.

Another quirk is that the Mr. Pi SDRAM does not seem to function properly on a de-10 nano. I got black screen in Genesis core and garbage in the Neo Geo. 3.0 ram designed for De-10 on the other hand works fine as a secondary ram in the Mr. Pi.

can you run memtest with the same SDRAM on both FPGAs?

AVP runs great.

Playing around with VGA_scaler some more, I found that resolution like 2048x720 can even be unstable, and the same shadow mask can cause sync drop used horizontally and zero problems at 2x or vertically.

My guess right now is that horizontal detail that would require rapid changes in analog frequency is hitting some kind of limit that causes sync loss. Would be curious if this is also a problem in the standard 9.2 boards. It makes using vga_scaler for high resolutions pretty dicey and I would imagine also an issue for Amiga RTG or simulating vector monitors.

Well I received mine this weekend, and so far so good. I swapped my sd card into the MiSTer Pi, and I can’t tell a difference between it and my OG from MiSTer Addons. This is a pretty excellent value, and I’m excited for the prospect of a handheld!

Saturn and Jaguar dual cores run great now.

Problem, no sound at all from the 3.55mm jack, that I had attached to an amp.

All cores affected.
Any ideas? Do I need to change anything? Or check anything?

Thanks.

Did you check the volume level form the F12 main menu?
I had a similar problem when I tested it with the sdcard I use in my Mister. The same sdcard worked fine on my mister but with no sound on the mister pi. And when I went to the F12 (F12 then Left) menu to check the volume, it was muted.

Yes, speaking to TAki to get sound out of the 3.55mm jack, you need that little board plugged in.
Except this is a dual ram setup, so that's that buggered, and you can't plug the sound board in.

You should still have optical/digital audio coming out of the 3.55mm jack, treated as mini-TOSlink. You can get some cheap DACs from amazon that accept optical, and a mini-TOSlink to TOSlink optical cable.

So, digital sound is coming out of the 3.55mm and then sort sort of converter to analog 3.5mm jack, then

a) I can plug it into my amp
b) when I want to use CRT, I'll get sound.

?

What a faff, anyone know of any cheap things that'll do the job? (with links)

Help! Thanks all.
