r/MiSTerFPGA

Just tried superstation one on my only remaining CRT TV, which unfortunately only has composite in. After flipping switch 3 to on and change profile to SVID, most cores I tried work fine using composite out, but I noticed some cores are not outputting video to composite.

So far I noticed the Neogeo Pocket and X68000 cores, as soon as I load the core, the video signal is lost. I tried to change the video settings of the cores using hdmi, but nothing seem to work. Do anyone know how to fix this issue? TIA!

Hi everyone. I'm becoming quite frustrated over here and hoping someone can help.

I'm a recent SuperStation One owner. Upon receiving the console I wrote the recent firmware to the supplied 64gb card, ran update_all. And everything worked fine.

Then, I decided to expand my card, so I got a SanDisk Ultra 512gb. I Then flashed the same firmware (1.0C I believe) and copied all files from the 64gb over plus quite a few other files I had collected.After some time, that card became write-protected for no reason.

I figured it was failing, bit the bullet and bought another. Brand new. Same card. Legit vendor. Did the same.

This time I only transferred files via network, thinking it might have been the removing of the card constantly from the SS1 causing the issue.

Now after a few weeks, that one has also adopted the same behaviour. Can't add. Can't delete. I can remove files from the card. That's it. Can't remove write-protection on PC.

Any idea what could be causing this?

Could this be a power supply issue? Would that initiate write protection?

UPDATE: I appreciate everybody's input. in follow up, the card came back clean on H2testw's write + verify test. So, while fake cards can be a culprit- no doubt - I don't think it is the silver bullet that most comments seem to think. something else is at play here, but I wouldn't imagine heat, as my SS1 does not seem to run warm. Anyway, I'm gonna try some lower capacity cards I have lying around. Ironically, the cheap card it came with is fine. Haven't had an issue.

I know this is a controversial issue. But I found this list in the net:

NES/Famicom - composite

Sega MD/Genesis - RGB

SNES - RGB

PS1 - composite

N64 - composite

Sega Dreamcast - RGB

PS2 - RGB

Nintendo Gamecube - composite

So it's official? Or are there other opinions? I would appreciate any responses, including those about other systems.

If somebody has no understanding of FPGA and considers entering this engineering area, what would be the appropriate reading? I do not understand why I cannot find such book. It seems to be as simple as adapting existing FPGA book to MiSTer FPGA. Whoever does it first, wins.

For me, computers were always a dualism of ability to play and ability to program. I was running Secret Agent, playing, exiting to DOS, opening Turbo Pascal and wanting to program something myself too.

Naturally if I am considering FPGA enginnering, I only view similar dualistic approaches. But I fail.

What do I know about FPGA? There is BORPH OS, and operating system with "software processes" and "hardware processes". What target does it support?

>The NetFPGA is a PCI card that contains a large Xilinx FPGA, 4 Gigabit Ethernet ports, Static RAM (SRAM), Double-Date Rate (DDR2) Dynamic RAM (DRAM)

Alright. NetFPGA then.

Let's move further. Prof. Niklaus Wirth has a course of FPGA engineering. Long ago he engineered Lilith PC and wrote Oberon OS for it. But Lilith PC is legacy, and his course of FPGA engineering was updated to FPGA. Guess which?

Digilent Spartan-3!

So to follow the FPGA course of Niklaus Wirth I need to buy Digilent Spartan-3. And why would I do that? What else can I do with it? There is just one interesting operating system, and display is monochrome.

And I open HDL books, and look what is their target. Again not MiSTer FPGA. This is the problem. They all want me to buy notably costly hardware, suitable for only one thing, and often not that good. MiSTer FPGA already solves problem of colorful hardware accelerated graphics with tiles, sprites, digital processed sound, network. Plenty of games and old computers.

I can hack all of that. Invent new x86 instruction and use it in Turbo Pascal. Or maybe make fantasy console? Its CPU can be MMIX, like in TAoCP. Why don't TAoCP people think of anything better than framebuffer and why don't fantasy console creators select MMIX as their CPU. MMIX-based stuff may ring some bells in Stanford and Munich.

I can see no reason to want anything but MiSTer FPGA as first and only FPGA setup. And if I program something interesting for MiSTer FPGA, my chances to present it to somebody else are higher than on all other boards. All roads go to MiSTer FPGA. Well, at least all FPGA starters' roads go to MiSTer FPGA. Then why I enter "MiSTer FPGA book" into search engine and cannot see anything sensible.

I recently got a crt monitor I wanted to use as my primary mister screen mostly because I want to play all kinds of stuff and can't really justify having a crt monitor and tv both taking up space. I thought I would just turn on scandoubler and be good but apparently that leads to a lot of problems such as 480i and the script menu not working.

I figure I can just use a bunch of overrides to have it automatically switch between scandoubler and vgascaler. I'm not sure what the best route to take with this is, my understanding is video= overrides are prioritized over core overrides.

Given my priorities of all screens visible, using scandoubler whenever possible, and least possible ini profiles what overrides do I have to account for and what would be the easiest approach?

Starting to put together a mister and the plan is to mount it inside an Amiga 500 case and treat it primarily as an Amiga; auto-loading its core and everything.

However that got me thinking. Would it be possible to build a physical switch that lets me select the default core? I mean I mostly want an Amiga workstation, but it would be really cool to be able to auto-load the 486 or C64 cores (or one that doesn't default load any core).

Where is the best place to buy a SNAC adapter in North America?

Any other recommendations for a low latency adapter for my wired NES, SNES, Genesis, N64 and PSX gamepads?

In the last few days, I've read a few posts about core development where a rivalry has begun between two different points of view.

The first preference is how things are built, preserving knowledge, craftsmanship, and the expertise of human core development.

The second is more about what gets built, making as many different systems available as possible for the community.

So what is the real goal here, what do you think?

Hi all,

I am in the process of building my QMTech into a blast city arcade cabinet.

I intend to use the VGA output as the cab has a VGA input on the monitor chassis.

I've read that QMTech's IO is the older style that supports 18 bit colour over VGA.

1. What cores actually use full 24 bit video? So far seems like PSX and N64.

2. Has QMTech released an updated IO board with 24 bit colour over VGA?

What tools do you suggest for this?

So I've been interested in checking out FPGA gaming for a while now, and ended up ordering a Hamgeek MiSTER. It's not here yet, but I figured I'd ask ahead of time if anyone knew where to find a guide to setting it up? The guides on youtube are all for an original DE10 Nano MiSTER or a MiSTER Pi, and I have no clue how applicable that'll be to the Hamgeek one.

If it helps, I'm not a total tech noob, I've fiddled with traditional emulators before and I've done the occasional command line thing on Linux, but I'm far from an expert (I have no clue how SSH works for example which I know people bring up a lot in relation to MiSTER). Also I'm aiming for arcade, home console, and portable console cores; not really interested in PC cores.
