Imho a lot latency or lag is overblown and a lot of these old systems were not latency free to start with for example a original SNES had up to 72ms or 3.6 frames of latency on a CRT Any latency inherent to the console will be known to the devs and compensated for with game design. But they didn't know about flat panels, and won't be considering e...

But aren't the USB hubs powered directly from the power supply, whether via a y splitter or a jumper piece that is what actually delivers power from the hub to the DE10-nano? If you route the power through the Mister, the most you can supply to the whole stack is about 4A, because that's all the DE-10 will transmit across the board. It has overvol...

Malor

Wall warts are pretty cheap. I would reserve 4A for your Mister plus any downstream devices you may acquire, and then budget another 2A for the screen. Use either a separate 2A supply, or a Y connector on a 6A supply. The Mister has overcurrent/overvoltage protection, so it won't transmit more than a certain amount of total power across the board t...

The SD card that came with my MiSTer, I copied everything to a folder on my PC for backup. I looked on this forum for recommendations for a 256 GB SD card, and even followed the link - to Amazon - and ordered it from there. When it arrived, I formatted it, then copied the backup folder to the new SD card. I put it in the Primary SD card slot, turn...

Depending on where that line is drawn some of the sixth generation consoles might just not be possible to implement at full speed on a current FPGA at all. Xbox's 733MHz Celeron seems like it would pose a major challenge, likewise for PS2's 400MHz DDR Rambus memory. I would be really, really surprised if we ever even saw an accurate Pentium 1 chip...

Dont use the 96k option. It may give issues with certain capture equipment. If you're not capturing anything, would it matter? I'm driving a receiver with a Toslink cable, and it works very nicely in 96K. I would anticipate that, in 2022, almost any quality gear that takes Toslink inputs should handle 96K. My receiver is from 2009, and I'm pretty ...

I vaguely remember that being a little weird. It wouldn't shock me if an ISO image lists all the files with the readonly bit set, and then copy perhaps preserves that bit. You might find it easier to use the 'shared' directory. You run the misterfs program under DOS with the drive letter you want, and suddenly your /games/AO486/shared directory bec...

It's really curious that you lose any ability to input to the Mister framework. Even if the core crashes, the menus should still work.

If you have a joystick handy, does that lock up too? And, just in case, how hot is your Mister running when this happens?

Oh, and does SSH keep working when the menu freezes?

Malor

As I understand it, you folks (Heber) can build most or all boards of the complexity class we're presently dealing with. It seems to me, then, that the primary question becomes this: is there another FPGA similar to or stronger than the Cyclone V that you can get cheaply, in volume? Are any of the FPGA makers out there willing to price their produc...

Malor

Did you try "country=US" in your wpa_supplicant.conf?

Malor

For digital signals, AFAIK base level is max volume, and that's where everything defaults. The signal sent through both HDMI and Toslink is at max volume/full resolution by default. (it's the same signal down both cables.) You can turn it down, but not turn it any higher. You may want to also set this: hdmi_audio_96k=1 which changes to a 96KHz samp...

I'd definitely try telling update_all to use names.txt; that may fix the problem right there. You'll get English core names instead of computer-ish core names. If you still don't like the naming, you can use the favorites script to create shortcuts off the main menu, and you can call those anything you like. I've normally used it to link directly t...

As far as I know, they're not linked in any way, so they don't need to be identical. They're like totally separate RAM banks on a PC.... within a bank, you want to keep RAM modules the same, but you can have different sizes and speeds in different banks if you want to. In effect, it's two separate RAM buses, so they just have to react fast enough t...

FWIW, I'm using an LG 27GN850-B. I think it's been replaced by a slightly newer GP series, but I haven't bothered to look. It suffers from black crush, so I'm not super enthusiastic about it as a movie monitor, but it generally plays very well with the Mister. 1920x1440 works flawlessly, and vsync_adjust=2 works fine almost all the time. There are ...

Malor

Note that the MT32-Pi software doesn't produce any HDMI output, so plugging it into a monitor won't tell you anything. If you want to test the Pi itself, disconnect it from the Mister (and probably the hat), and try powering it up with a regular OS microSD card plugged in. That will tell you whether or not the Pi itself is working.

Malor

As I understand it, if you use a CRT, either via the analog I/O board or through Direct Video, and you don't engage the scaler, you have 0 display lag. What you see on the CRT happens at exactly the same time that you would have seen it on real hardware on a TV. Depending on your controller and how it connects, you may have control lag, which is a ...

Myself, I probably wouldn't be a purist, and would run the EasyFlash version. You're in the same situation you would be with a real 64; the Mister is being accurate, and you're doing what real 64 users would do.

That way, you don't have to wait for a C128 core to be finished.

Malor

Yeah, that sounds like you might have the read-only bit set on some or all of the files. If you go into the game directory, typing: attrib -r *.* should remove that flag from all the files there. If there are subdirectories, I think you have to go into each one and do that. I don't think it will recurse through directories, but I haven't really tes...

Malor

As a thought out of left field: what's your cooling situation like? Is the Mister reasonably cool to the touch? Mine gets really weird if it gets hot; it absolutely requires an active fan blowing on it for many cores.

Malor

Do that deletion while you're at the main menu, not in Burger Time, and then reboot again before you restart that core, just in case.

(The reboot probably isn't necessary, but it takes like ten seconds, so what the heck.)

Malor

I recently used a DS5 to play through Final Fantasy 9 on the PSX core. I used the little bottom-center button for the menu, which I think is probably the Mute button, and I never once saw a problem. It worked perfectly every time. I did run the firmware updater ahead of time; I'm presently on version 0307, and the tool says that's the current relea...

Malor

Yes, we had kinda figured that out already.

Edit: I just discovered that when I go reset settings, then it comes on again. But I can't get it to run without doing that. I mean, it's not the end of the world, but it's not quite right. I can live with it though. Try resetting the Burger Time settings, and then saving them. That might fix it permanently. edit: it's also not that unusual for co...

You need a Kickstart rom (BIOS). This really makes me cringe - only x86 PCs have (had) BIOS. Nonsense. The concept of a BIOS predates the x86 PCs. It was created in 1976 by Gary Kildall for CP/M. At this point x86 processors didn't even exist (the 8086 were released in 1978 and the 8088 the CPU in the first IBM PCs was released even a year later i...

The snow is still working here. I have a single "menu.jpg" file in the main Mister directory, which is normally my background. If I hit F1 seven times, it cycles through various color bar patterns, then a black screen, then snow. If I hit F1 an eighth time, it returns to menu.jpg. Note that the Mister binary was updated relatively recentl...

Malor

Did you have any power failures over the holidays? The DE-10 is pretty resistant to overvolt and overcurrent, but a big surge when the power was restored could definitely kill it.

Malor

Lots of the DC power switches are poorly made, and will reduce voltage as it crosses. The problem tends to worsen over time, and can start to cause cores to misbehave or outright fail. It can also cause overheating issues. And if you're using a Y cable, of course, then the switch only turns power off to its segment, leaving the other segment (the U...

I was looking for Paperboy the other day. IIRC, that's a really complex system that will be a major pain to reimplement, but I'd love to see it.

Malor

The Pacman core was ported, right? Is there any reasonable way to find out how accurate the original version was, and which hardware version it was re-creating? As far as the 4-way/8-way thing goes... I haven't tried this, but you might be able to map the four buttons on most controllers to be L/R/U/D. If you were then precise about your button pre...

I just bought one of these:

https://www.amazon.com/dp/B07KFMNJLH

and while I'm not using it for the Mister, I'm sure it would work fine. It's a wall plug extender with a 6-foot cable leading to a soft on/off button on a little puck. The puck has a screw hole on the back, so you can hang it on something.
