MiSTery Atari ST/STe core

Postby markun » Sun Aug 25, 2019 4:54 pm

I see that there is an open source Atari ST/STe core available for MiST:

https://github.com/gyurco/MiSTery
viewtopic.php?f=115&t=37297

Is anyone looking into porting it to the MiSTer? (I'm not volunteering :wink:)

It's using the FX68K CPU core from ijor.

I could have posted in the FX CAST Atari ST thread, but didn't want to hijack it since this is about a different core.

I know about this core. Will try to port it later.

Thanks a lot Sorgelig.

I want to see this core in miSTer.

Looking forward to this one also (since the FX Cast core seems to be a lost cause).

I would be very happy if the Atari STe would finally come true.
I've been waiting a long time to finally play "Obsession Pinball" again - just like 25 years ago.

I had a 1040STe with TOS 1.6

At the moment I always have to dig up the MIST FPGA and a CRT first.

Greetings Lutz

Why do You need CRT for MiST? It works with VGA LCD monitors just fine.

Me three. I still use my real ST via OSSC because i want to use HDMI and the current fxcast core is forced 16:9 over HDMI - the biggest sin in retro gaming is 4:3 stretched to 16:9 :/

I really don't like the joystick port issues on my real ST but at least the screen is right.

Is anyone really working on porting this core? It would be such a great addition to MiSTer to have an Atari ST-Core which is more on par with the recent capabilities of MiSTer than the FX-Cast core.

Before someone comments: I personally lack all required skills for this task. I can only express my hopes...and donate some money :oops:

Advanced system such as Atari ST needs dedicated developer. Developer who knows ST at some level to know how to test and fix small problems while porting.

Yes I can only imagine the amount of work it takes. Let’s hope that someone with enough love and dedication for the ST (and the skills) is willing to invest his time.

I will port the core. Just need to find the time. Hopefully shortly :)

That would be brilliant, Ijor! Crossing my fingers that 15kHz mode will be possible :wink:

I know about the original ST core for Mist, and now this second core Mistery, which I hear is cycle accurate if I'm not mistaken. It is nice to see this may get ported to MiSTer as well.

Wasn't there some original ST core for Mister though? Was that the FX one? The main MiSTer page seems without ANY ST core. I may have missed any news on why, but since the Atari ST is the 'ST' in MiSTer along with Amiga's minimig core, it just surprised me. I'm only guessing from this thread. Is it that the FX core needs updating, but now that Mistery is the best ST core (IF that is correct) in FPGA, it just made sense to take down the original core for the eventual Mistery port to MiSTer?

Yes, the fxcast core is the current Atari ST core. According to its creator, it has very specific design goals... a cycle-accurate 68000 (8MHz I believe), all of the support chips provided in the original ST model... with TOS 1.0 baked-in. What it does, it does very well as the vast majority of games and demos run on it very well... just like the real thing.

Of course there are some of us wanting more... hard disk (image) support... more RAM (fxcast originally was 1MB only but has since moved to up to 4MB), maybe a more powerful flavor of 68k at a higher clock speed... and definitely the ability to run different ROMs, OS flavors (TOS, MultiTOS, MiNT, Geneva/Neodesk, etc)... and especially more of a focus of using it as a computer in addition to a game machine and demo runner. I don't think we could get a 68030-based Falcon clone is probably asking for too much. MiniMig has 68020.

I ran an Atari ST system (several different models) from 1985 to about 1996. I had a CD-ROM drive and removable media hard disks (similar to ZIP/Jazz drives but different) working with my Atari without any real hardware hackery. We only had dialup BBS and pay service access. I very fondly remember CompuServ and GEnie's Atari sections and the offline readers we had. I ran MichTron BBS for a while and later FoRuM ST on the FidoNet-like network they had... and the QWK offline message readers. I never got ethernet nor TCP/IP working on the Atari but I know some people did.

After having written all of that, I'd say there are three distinct directions:
1) Preserving the Atari ST as a gaming machine (fxcast is very close)
2) Providing support for the wider range of hardware and capabilities that were provided by later Atari models and firmware
3) Extending beyond the original to provide a somewhat more modern environment

I guess #3 is sort-of-like wanting to revive the platform for a very niche market (hundreds maybe thousands?) of people who might want that. I see that as the roll that MiniMig is doing for Amiga users... but I'd be very happy with the move to #2 if the MiSTery core is something that could provide that.

I have been fairly happy with the Hatari software-based emulator running on top of Linux but getting a quality FPGA implementation is desirable. I would be willing to donate money if someone were to do a crowd-funding effort for such a project. A am not a programmer nor a EE/ECE student/grad so no needed skills to help out.

It actually has some nasty bugs.. one being the odd default video mode the core has, on many monitors (mine included) it fails to produce a compatible signal so you cant even see the core output or even mister menu, nada, nothing. just (on my display a floating box saying INVALID SIGNAL) .. i had to blindly .. by keypress alone (provided by someone telling me which keys to press in what order) force the 60hz display mode.. it also defaults to 16x9 and doesnt respect aspect ratio (both of these are due to its lack of supporting the now common mister frame buffer).. It lacks disk-writes, locked in UK TOS 1.0 (would be nice to have the option to use US TOS 1.0 or others etc) .. and a slew of other things.. while yes its cycle accurate its broken in many many ways.. and without the source being published, no one can take up addressing these faults unfortunately. .. the author seems to have lost interest or has had other life issues crop up (which happens)..

personally id rather have a working less accurate open source core than an accurate, closed source, incomplete/fundamentally broken core we got now.

Lastly, Sorgelig is correct in saying that a complex system like the Atari ST needs someone who understands it at a deep level.. right now I dont think there is anyone out there who does and has time to do it.
