In /Games/Zet98 : boot.rom
in /bootrom : Zet98.rom

only one of them is required and it's better to have only one

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.

I have the same problem with this version and the last realese of main MiSTer, no osd menu !!

But I hear the two Core boot beeps
Seems to me that was not the case before

Great, thanks for your clarifications. I will keep it in mind.

you need to rename it Zet98.rom in this folder

Thanks! 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!

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!

Same here, I have tested it with the latest Mister release and I only get a black screen with an empty purple box in the centre of the screen.

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

Ah! You were right! I kept bootrom/Zet98.rom file! That's why it was working! Sorry my fault!

it's for this reason, that I told you that it is better to have the file than in one place

Yup, you were correct. I have edited my previous post to avoid confusion!

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.

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

I uploaded the latest Template core compiled with Advanced Setting (Synth and Fitter) of Compiler Settings.
https://fpga8801.up.seesaa.net/image/Zet98_20210109.rbf

There is still something wrong with the graphics screen. 200 lines cannot be displayed normally. The 400 line is displayed normally on DE0-CV to some extent, but for some reason MiSTer crushes the height in half.

Hi Puu,
I have the same issue no OSD with the last RBF Zet98_20210109.
Thanks,

Sorry, puu san ! Same behaviour and nothing new. I think you've got a problem with video timmings.

Hello Mr Puu

Same issue with the last release of your Core and the last release of the main MiSTer.
With MiSTer_20201027, no issue

What exactly is Quartus giving an error message on the VIDEO clock?

Hi puu,

As mentioned by other users above, same behaviour here.

At this moment I am not at my computer, but I remember that it had to do with a video clock.
Something like: CRTC98 : VID | VTIMING : TIM | clk3sft was determined to be a clock but was found without an associated clock assignment.

I have this line :
Warning (332060): Node: emu:emu|Zet98MiSTer:Zet98_top|CRTC98:VID|VTIMING:TIM|clk3sft[2] was determined to be a clock but was found without an associated clock assignment.

Hello,

But why don't you have an issue with the latest version of Main MiSTer? It doesn't work for anyone !

The OSD lockup seems to be related to the parsing of CONF_STR. Commenting out the following line (in Zet98/MiSTer/Zet98.sv) fixed it for me. I don't understand why, because I don't see anything wrong with the syntax; I just found it by trial and error. The core still doesn't run consistently on my setup, but I think that's a different issue.

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...
