My vote is on a Saturn core :P Only because someone else is working on something has never stopped Robert. He has his own ideas he wants to achieve and that also includes going beyond what the hardware could do like what he did with the PSX core. Robert didn't begin working on a PSX core until laxer announced that he wasn't working on it any longe...

The whole secrecy thing is annoying. He said it’s in case the core isn’t doable but he announced PSX knowing it may not be doable. Makes no sense. One day, when you learn the personal pressures of having thousands of people waiting to overreact to something you work on, you will then know why he's being secretive about it. He's managing expectatio...

The only advantage would be shaving about 1 frame off in the whole signal chain that is already overwhelmed by latency. When you do cloud gaming there is a balancing act between the quality of the video stream and the latency. Better latency usually means worse video quality, and vice versa. You can get both, but the bandwidth goes up a ton. Then t...

darfpga developed the core, not me and he would likely be the one to do it. I don't think he has a patreon.

Did you already confirm everything is setup according to the instructions given to you by the seller here --> https://www.retrocomputershack.com/ebay-Listings/MisterFPGA-Scart/mister-fpga-scart001004.jpg If so then check this --> https://mister-devel.github.io/MkDocs_MiSTer/advanced/crt/#for-io-board And this --> https://mister-devel.github.io/MkDo...

aberu

That core isn't locked behind the patreon paywall, so this message being received means either you have an older beta version of the core on your system or something went wrong with an update.

aberu

No, I didn't just say if you aren't happy do it yourself. I also said it's really hard to do this stuff since the obvious implication of your post was that certain things (like NGPC) are taking too long and you don't appreciate the cores he's releasing anymore because they are games you don't like. You are entitled to your opinion, and I'm entitled...

What is the thinking behind him putting all his cores in the one github repo? I thought the general thought for larger projects is you don't do that. Going to make checking and logging issues messy. Actually the way he organizes his repos is more initial setup but it's less management in the long run as long as you keep all the integrations workin...

aberu

If you think you can do better, go ahead and learn how to make cores yourself I guess. All you are doing by complaining is making other devs and prospective devs not want to be involved in this community.

There is a Discord Thread under the mister=cores / Neo Geo channel for those with Discord

i think i am not in that discord channel. Could you invite me to it?

The checker pattern coming up probably means that the file is either corrupted or invalid in some way. Can you try and rule out which file it is and then attach it here (filename intact and everything) please?

aberu

Can you provide an example homebrew game that lets you do this?

aberu

Possible? Lots of stuff is possible. The technical limitation is, as Bas rightly pointed out, the potential for causing issues with achieving timing closure. It would likely require a fork of the core with a bunch of stuff ripped out and a bunch of features of the MiSTer framework disabled or taken out. It's not as much the logic space, it's the co...

I mean it was already technically available... on the PSX core.

The hardware for this also can run:

So it's not just this one game potentially

...as it’s showing its age and cost are still rising significantly, it’s starting to feel like a dead-end. It's too presumptuous to call it a dead-end at this point. Terasic still makes the boards, if you order from them directly you get them in a couple weeks (when it's not christmas time), the price went up, but it's still cheaper than getting a...

For 24-bit tests over analog video testing you could load of Castlevania Symphony of the Night on the PSX core (please note, the analog io board is 18-bit video only, direct video is 24-bit however). Just keep the 24-bit dithering turned off in the OSD. For HDMI, same thing, it actually uses 24-bit. If you need a raw gradient testing, then you woul...

Yes, something like ABL should be disabled with a service remote control.

"should be disabled" is not something I would ever give as advice. It will violate your warranty and it will increase the likelihood of burn-in occurring.

How good it will look will be somewhat subjective, it will depend on your TV, it will depend on how long you mess with the other options associated with it to get the gain and offset for each color dialed in right, and even then it won't be a correct color matching. The fact is, using scanlines and shadowmasks already mangles the color somewhat, so...

The MiSTer core is a port of this core --> https://gitlab.com/SpectrumNext/ZX_Spectrum_Next_FPGA for reference. Can you link to the facebook post for this? I can't find it. Sorgelig has added some significant improvements to this core, for instance adding additional prefetch to the sdram to increase performance, improved the wait states, etc... Whe...

Your Main MiSTer binary needs to be updated too, so make sure you run the downloader script first. If you added it to the end of your MiSTer.ini, make sure it's not underneath another "[core]" bracket exception.

First off, are you in Europe? Just making sure you are ordering from a seller that ships cost-effective to your location.

Try enabling fast polling on usb, it will overclock it to 1000hz. You may need to adjust the mouse speed in the MiSTer.ini afterward.

Why can't we have scanlines at 2x scale? I tried shadowmask instead (2x rotated Sony PVM), which works but doesn't seem to be integer aligned so doesn't look quite right. I'm trying on some 480i PSX games (Tekken 3, Ridge Racer Turbo). I think because 480p resolution scanlines are intended to be used with the scandoubler and the PSX core doesn't u...

The implementation cost could be painful, but the ongoing maintenance burden, after the initial bugs were squashed, probably wouldn't be significant. It's not like the archive format changes, so once the code works, it should keep working without much, if any, attention. But it's still a 'nice to have' feature, and I'm sure Sorgelig has many more ...

7zip support would be nice to the users to some degree, but it would add some cpu overhead since 7zip compression requires more cpu time to decompress. In general sorgelig doesn't want to add support to it because he doesn't see it as necessary. It could also introduce more code maintenance issues long term for him when he's the primary maintainer ...

aberu

Correct, not all sets are in 7zip, but many on the archive are because 7zip compression is better, so it reduces the upload time. It's best to just unzip the .7z roms, and then if you want to rezip them again for compression you can zip all of them into one zip file, no need to do them individually. The exception being, don't zip up cd images, they...

aberu

The technical reason is because otherwise some cores would write to the microSD multiple times a second (which will ruin your MicroSD card quickly) because of the method to detect that a new save can be saved.

You know what, I had a big reply, but I think we both said what we needed to say, and it's just drama to argue back and forth

Thanks for your hard work on the core Rampa, the more simulations of this classic hardware the better.
