PC98 Core
Re: PC98 core
Hi Puu
Unfortunately the core shows a black screen. In fact I have left it running for a while and it does not load anything. The BIOS is correct and definitely not working. I'm not going to do any more tests because it's a waste of time. The only thing the core shows is the ROM loading progress bar. There is no way to assign disks to the core, so what you suggest cannot be done.
The Quartus complains that the video clocks are wrong.
The only thing that the core does is pull out a maroon box that seems to be the framework menu but it is never completed. By the way, the MiSTer stays set and stays dead until you reset it.
I have tried HDMI, VGA, I have tried everything without any success.
You say that it works for you? Because nothing works for my colleagues and me. It's a pity.
Anyway thanks for your work.!

Re: PC98 core
Hi Puu,
Thanks for the work of the core.
If i understand correctly as you said "Since Zet is equivalent to 8086 / V30 / 80186, the BIOS of the model at that time is required. As for the era, if it is not the BIOS of the era of PC-9801VM and PC-98DO, the instructions related to protected mode are used in the BIOS and it will not start."
We need to find bios working for Zet core.
PC-9801VM is produced in 1985 so we need find bios of PC98 before 1985.
some version of PC 98 of this list can work with Zet98 ?
(from wiki: https://en.wikipedia.org/wiki/PC-9800_series)
Thanks again!

Re: PC98 core
It doesn't matter if you have the right BIOS if the core doesn't work. I think that first the core should work without leaving the MiSTer hanging.I know that I am using the correct BIOS but as I have already mentioned, it does not work for anyone and the effects are the same. Until puu can verify that the core works and video is painted on MiSTer all is guesswork.
I ask: Is there anyone for whom the video has worked well and without leaving the MiSTer toasted with the pc98 core?

Re: PC98 core
Hello Mr Puu,
I have found where the problem comes from.
It's the version of the main Mister that's causing the problem with your Core.
With the latest version it doesn't work. If I go back to a previous version, it's okay

Well done, thanks for sharing your findings!
Could you just please confirm which main Mister version you used?
Also would you mind sharing the BIOS as well?
Thanks a lot!

Re: PC98 core
By the way, the relationship between sys / sys.qip has never been updated, and both X68k and PC-88 use the same version.
Will these also not start with the latest MiSTer?

Re: PC98 core
Excellent, thanks for that! Could you please confirm the location for it?
I have placed it within the folder /media/fat/bootrom
but it didn't work.
Do we need a SDRAM file as well like for the x6800 core?
Thanks a lot!

Re: PC98 core
In /Games/Zet98 : boot.rom
in /bootrom : Zet98.rom
only one of them is required and it's better to have only one

Re: PC98 core
I updated MiSTer to the latest version with update.sh earlier, and it became v210103, but it starts normally with the original binary.
Just in case, I uploaded a replacement of sys with the latest template core.

Re: PC98 core
That's very odd! I have tried again and I have put those 4 files back in the folder /media/fat/games/Zet98 and they worked! Sorry, I have no idea!tontonkaloun wrote: ↑Fri Jan 08, 2021 2:35 pmAlkadian wrote: ↑Fri Jan 08, 2021 2:21 pmThanks! It worked like a charm!
I did another test and it also worked by keeping the same name boot.rom and by putting the file in /media/fat/games/Zet98.
Also I have tried the attached BIOS files which I put in /media/fat/games/Zet98 and also worked. But I am not an expert so I son't know if they are the correct ones. I have used them in retroarch.
No, your files don't seem to work!

Did you delete the /bootrom/Zet98.rom file?
in addition, you must rebuild your boot.rom file from these files. It shouldn't work like this

Re: PC98 core
Just out of curiosity I have tried one game, Albion. I have converted it from .fdi to .d88 with D88 Virtual Flooppy Converter, but it didn't work. I mean it boots up but then I get lots of graphical glitches.
Re: PC98 core
Same looks like games have double screen top and bottom kinda glitch...
I tried:
1. Thexder
2. Hatris
3. Deflektor
4. Slip Stream 92
All these booted, but various graphical glitches over HDMI.

Thanks puu ! we're close but still not working. Have you updated the MiSTer framework part?
Now when starting i can hear two beeps and in the screens seems like forming a matrix that disappears. This haven't happened before.
But, still black screen, maroon square as OSD ( NO OSD ) and MiSTer hanged.
My MiSTer is v210103, OS 200908
