Bang ! Bingo !

ExCyber , you got the key. Thanks.

After several I / O errors, I realized that from the OSD (which already works) you can configure the options of the machine.
So once I checked it was working and with a DOS 6.2 disk for PC98, this is the result.
I'll take a look, there's a lot to test.

Thank you @puu for your hard work
Thank you @ExCyber,
Works also on my side with the latest Mister revision

I did some more experiments. The OSD hang happens when the combination of option name and current value is too long. The combination of "DIP2-6 Fixed drive" and "Disconnect" is 2 characters too long. So one possibility for why puu (or anyone else) might not see this problem is a saved setting of "DIP2-6 Fixed drive" to "Connect", which does not cause the problem.

Likewise, one workaround is to replace "Fixed drive" with "Hard disk", which is two characters shorter (but sadly loses 100% of the '80s PC jargon vibe). I've attached a .rbf with that change in case it's important to anyone to be able to flip that switch, although it sounded like HDD emulation isn't working yet (?).

I'm not sure what the actual failure is, but I guess it's probably something to do with overlapping memory regions in the menu code (various typical algorithms and library functions don't work correctly for overlapping regions).

@ExCyber,
Many thanks for sharing your findings.

Guys,
Would you please let me know if you have managed to run any .d88 games? All the ones I have tried so far boot up but have many graphical glitches/issues as if the screen was replicated 3/4 times.
Thanks!

I tried converting some .fdi games to .d88, I only get a DOS loading screen and then it goes black...

Thanks for your feedback. Hopefully this will get fixed soon.

I used HXCexplorer to convert the the .fdi to d88 but I got the same as your result, the game is unplayable due to many graphical glitches

Same here, all games I converted with VFIC showed only garbled graphics.

Thanks for your feedback as well!

Thank you everyone for investigating the reason why it does not start.
I uploaded the corrections for that part and other corrections.

Hi Puu,

That's great, many thanks. I can't wait to test it!

That's very handy as usual. Many thanks for sharing tontonkaloun!

Hi,

Thank you puu for the updated core. It boots into DOS just fine, but I'm still getting the corrupted/duplicated screen issues Alkadian described. Here's what I'm seeing:

Even on Thexder, Hatris etc similar dual screen.

Thank you Mr Puu for the last release
I will test

Added support for 200 lines of graphics screen.

Interesting core, I hope the 8086 part can be used for other PC MS-DOS cores.

Thank you puu, its graphics glitch gone.

@Puu,
many thanks for this update.

@tontonkaloun
many thanks for sharing the .rbf.

In my case I am still experiencing the duplicated screen issues. Below my settings as advised by Puu:

DIP1-8 Extend
DIP1-3 Normal
DIP2-1 1
DIP2-2 Basic
DIP2-3 80
DIP2-4 25
DIP2-5 Keep
DIP2-6 Connect
DIP2-7 Control
DIP2-8 2.5MHz

I would appreciate your help. Would be possible for you to share the same .d88 files (YS 2) to see if mine are corrupted? That would be very much appreciated. I have been using different versions but to no avail.

Many thanks!

Fantastic, many thanks for that! That worked like a charm! Would you please let me know how to config the buttons? Thanks a lot!

Strange, this release version Zet98_20210116 wont boot, black screen and no OSD very like the first .rbf version.
The Zet98_20210115.rbf works, can load dos6.2.D88 and the Ys_1.D88 loads but the grafics are glitched...

Using this bios you attached on other post:

this is strange, because this version works fine on my MiSTer with these files

Guys,

I have being doing further tests. Basically if I run the game Albion for example, it looks like the graphic is OK when it boots up but, after 1-2 seconds, I get the duplicated screens issue mentioned before. Attached a few screenshots:

Also did you manage to setup the controls with any game? Maybe I am missing the obvious but I couldn't figure out how to do it.

I have also attached the game in question.

Thanks!

Excuse me. The gamepad is connected to the FM sound source GPIO, but the FM sound source is not implemented yet. Therefore, even if there is a gamepad setting, it cannot be used. HDD is also set, but it cannot be used.

Hi puu,

I see now. My fault, I was not aware of it. Many thanks for your kind explanations. Very much appreciated!

The addresses of screen 1 and screen 2 of the graphics screen overlapped by half.
It takes time to upload, so if you are compiling from source, you can fix it by modifying the following.
mem_addr_pkg_MiSTer.vhd (for DE0-CV people, mem_addr_pkg_DE0CV.vhd)
Near the 16th line
was:
constant RAM_VRAMB :std_logic_vector(27 downto 0) :=x"0048000";
is:
constant RAM_VRAMB :std_logic_vector(27 downto 0) :=x"0050000";

New rtl was uploaded.
