To be fair, you don't need this core to use a Pi with a CRT, you can use a Pi hat, such as the Pi2SCART. Then you get to use whatever MAME, or emulator you want, and the resolution, and refresh rate should be the same as the original hardware.

I used to do that but the advantage of PC is huge. Less lag, much more games, etc.

akeley

Of course not. Modelines are calculated by the emulator on the client and sent to the MiSTer, as game demands, but there's no extra configuration needed on the client side. This might even work on a Mac probably. You have full control though on video timings through the usual Switchres settings, in case you like to tinker. That makes it all more a...

It's not a bad idea, but as usual the problem is finding somebody to execute it. This is what has just occured with the out-of-the-blue Groovymame core - a very niche thing, for which there already is a solution. and yet some enthusiasts made it happen. In this case it could be useful because MiSTer owners also often collect old micros. And some of...

I woke up and still have trouble believing this is real

One more question: do we still have to deal with modeline creation on the PC side (using VMM, ArcadeOSD, etc) ? Quietly hoping NOT, because this bit could be a bit of a 'mare when trying to set things up and then also running Windows in low res....

akeley

Thank you, this made my day...what a great start to 2024. I have to actually upend/move my whole setup again this week but hopefully will be able to test it later this month.

Ok...so groovymame runs on PC, transfers data over LAN to MiSTer, new core processes it all, and MiSTer then outputs it to CRT, connected just like before with native cores? Tha sounds quite revolutionary and if there are more emus adapted - well, Retroarch really - it would let me get rid of my specialized Groovy PC box with olden ATI card and run...

akeley

Wow, this sounds quite wild and exciting, seeing as I love Groovymame, MiSTer & CRTs .... but I must admit my senile brain has a hard time trying to process it all. I connect what to what here exactly? PC running groovy to MiSTer to CRT TV?

The chip is the CS5210 which is considered good by the guide, except in one occasion: when it's inside a Vention adapter, and guess what? My adapter is Vention branded.

The star rating in this guide refers to image quality. The adapter itself should still work regardless of that.

Megadrive has "pause when OSD is open", SNES doesn't. Any RPG or strategy game would do, but better use this "industry standard" tool for calibration: https://artemiourbina.itch.io/240p-test-suite

I thought the scandoubler option took care of that. It sure does, they're just plain wrong (at least in regard to CRT monitors). Plus, you don't even need the scandoubler, like I said previously (but might need some modelines). Overall, I can run every core on a VGA monitor (one of which is old, uncommon, and very fussy), including 15kHz PAL micro...

According to the Direct Video MiSTer FAQ/guide I only need to change two parameters in my "mister.ini", is it really all that it's needed? That should be enough. Your config looks like the old version though, best use the most recent one in such troubleshooting cases: https://github.com/MiSTer-devel/Main_MiSTer/blob/master/MiSTer.ini Try...

akeley

Sorry, for me making modelines is still black magic - I only copied it from someone. Maybe somebody else can chime in, and you can also try to read this guide for more advanced insights. Ata a glance though 490 is a near-multiple of 2x240 (a bit like old DOS games), and 4x320=1280, so 1276 (it's ok to do super-resolution in horizontal). The result ...

akeley

it's just bugging me when these errors happen and I don't know why. Yep, I get the same itch. But our results aren't completely different - without modelines I also can't display on VGA monitor or normal consumer set, it's the same, normal behaviour. Just that Toshiba not displaying 1:1 image and having scaling problems when using my config is str...

akeley

This was via analog, but for the old times sake I've just tried it via Direct Video (with that aforementioned adapter) and it also works - this time on consumer Trinitron set. The numbers are the same.

akeley

It's a 15kHz modeline and works ok for me: IMG-20231224-160243.jpg One problem is maybe you're using Direct Video? In that case I don't think modelines will work unless you have an additional adapter (like UMSA ). Also, some TVs are more or less sensitive, though, amusingly enough in my experience it's actually PVMs being more fussy. You can also t...

Try this

I got a new update_all.sh, ran it, and it brought in the Minimig core. Now the Amiga core entry launches Minimig, and the Amiga 500 core asks for a Workbench disk, so that's progress... For hdf images like MegaAGS/AV you should use Amiga 1200 config and mount the hdf files plus Kickstart file. The MegaAGS readme describes which settings to change ...

I've seen numerous times on this forum when talking about a problem/request results in a positive outcome (or at least an attempt at achieving one).

Thing is, if I run the pcxt core the txt is not garbled. In the mister menu I can see it outputing 15kh but in ao486 I’ll see a higher kh number. These are two different cores/machines. PC/XT outputs 15kHz CGA signal and ao486 dodgy 31kHz VGA. That's why you need modelines for ao486 to be able to display it on 15kHz at all. And the DOS vs in-game ...

This is a little something I made to have a fun break from my more long-term archival projects. From the description: This collection contains games from 5 different Top 100 ZX Spectrum games lists. Overall it features 274 games altogether (full list below), plus some additional media (scans, instructions, loading screens, and .ay music files). The...

Tried all the modes on the ao486 core but it refuses to output a 15kh signal. One of the modes looks pretty great in games but dos txt is always slightly chopped off and can be hard to read. If as you say "it looks great in games" then that's 15 kHz modelines working as intended. The trade off is the slightly garbled text in DOS, but the...

akeley

Thank you, I tried your link to the wiki but it directs me back here to this post. Does anyone know what video mode this core (pcxt) uses to support analogue rgb output to a pvm. In the ao486 core, everything I’ve tried via the mister ini and custom video modes to get an image either doesn’t display correct if at all. The one mode that I get an im...

Most of your problems with running games are described in the wiki (need for XTIDE bios, only 360kb images for Tandy). Regarding the colours, I think Space Quest on Tandy uses EGA-like graphics, so they might be different. EDIT: I see now you're talking about pcxt mode, so scratch that. If you're interested in games with Tandy-exclusive fx you can ...

One way to go around this is to distribute only the files on a hdd image without the OS. That's what I did with my collection and it's still up on the archive, touch wood (though it's much less known too). I believe you could set it up so that the frontend is still there, only that the user needs to have their own primary hdd image with the OS on i...

For the best versions I recommend getting Total Dos Collection and Gruby's Floppy Images pack. These will save you a lot of browsing.

This sounds like the old mouse problem which was plaguing this core, eg: https://www.misterfpga.org/viewtopic.php?p=34027#p34027 I used to think it has to do with "mouse_throttle=" in the mister.ini, and that setting it to "1" helps, but I think some people said it didn't. Actually, now I seem to recall it might be connected to ...

I plan to use the optical audio out, so I take I can choose the simple version of the adapter and disregard the one with power and audio, right?

Most likely yes, but it's been a long time since I've used this solution and I don't remember the details. Maybe somebody else can chime in.

I've tested Ricardo's previous cable, the one without lightgun, and it was fine. Far as I know, they are based on the AG6200 chip, which, if you read this thread is suppsed to be "some of the worst out there". What that means in practice is that the displayed image might be somewhat darker, which, as you can see me arguing there is not ac...

Contemplating a change to the method of distributing the files. Git repo isn't the best for binaries. I use archive.org for all my collection projects. It's not ideal, but allows for the stuff to be findable by general public. They have also improved their uploader/UI in general, so it's now less of a PITA. You can drag and drop files and they wil...

I think I read somewhere that Falcon needs FPU? Or maybe requires FPU for certain flight models, while non-FPU operation is also possible. So perhaps it can be tweaked in options? EDIT: The manual says: NOTE: The HF flight model requires a math coprocessor, 80486DX or Pentium to run. If you don’t have a math coprocessor, the game will default to th...
