PC98 Core

[Alkadian]

@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!

Thank you Mr Puu for the last release
I will test

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";

Thanks Mr Puu

What other files (bios?) do I need to be able to use this, please? I'm excited by the fast progress and want to try it out.

I tried that file and I just get a black screen and a few beeps... Is that normal or am I doing something wrong?

[mapf]

I managed to get the core running by copying the provided boot.rom to Games/Zet98, setting the switches in the OSD to the values described in one of the prior posts by the developer of the core and inserting a PC-98 MS-DOS disk in D88 format. I saved the settings in the OSD, and reset using the OSD function.

Blank screen appears to be normal, there were no BIOS messages during startup and it takes a little while for DOS to boot.

Thank you @puu-san for your hard work.
On last release, I can hear sound on some games and I'm able to use game pad on YS 1 now

Would someone mind re-posting in a manner allowable by the forum rules (like the previous expired link to swisstransfer) the bios boot.rom file, or provide instructions on how to recreate it, or perhaps email me a copy? I managed to create a boot.rom file from bits of the pc9801f.zip that is part of MAME, and it will boot into NEC D88 Basic, but I cannot get it to boot from a D88 floppy image for the life of me.

Thanks in advance!

Nevermind! I re-read the entire thread again and realized that the BIOS.ROM that one manipulates with Mr. Puu's BIOS/mkrom.sh is really IPF.ROM from a PC98-DO. Or at least that works!

Thank you to everyone for testing and especially to Mr. Puu for the amazing core!

[killersquirel]

Where did you find the IPF.rom file?

[tontonkaloun]

@Mr Puu

Thank's for the new version

Thank You Puu-san

Hi everyone!

Recent Mister user and I'm having a blast with the x68000 core! Thanks Puu for the amazing work there!

Now I would like to give the PC98 a go. Problem is that I'm unable to unpack the qar file to generate the bios. Could someone please send me the mkbios script?

Thanks!

hello

Thank you so much for this! Finally able to boot the core now!
Took me a while to figure that the GDC clock was screwing up the image of the games.

Now looking for a HDF to HDI converter and I'm golden. Thanks again!!

[Alkadian]

Thank You Puu-san

I have missed this update!

@puu thank you for your very much appreciated work!

@wark91,

Would you mind sharing the .d88 of Rusty? I have tried to convert the .hdi version with virtual floppy image converter but the .d88 I have got doesn't boot at all.

Thanks!

[wark91]

@alkadian, what is the software you use to convert floppies of Rusty ? Is vfic ? Is the floppies converted working on the PC 98 emulator ?
Do you have just black screen or a message ?
Thanks,
