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";

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?

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!

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!!

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!

@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,

Most archives targeted at emulation will contain hard disk images, and I have not found a way to use these with the PC98 core.
I found floppy disk images for many titles in the "Neo Kobe - NEC PC-9801 (2017-11-17)" collection on archive.org. You will need a disk image tool to convert to .d88 files. I use the "Virtual Floppy Image Converter" from
https://www.vector.co.jp/soft/win95/util/se151106.html
I managed to boot Rusty from the floppies from the "Neo Kobe" archive and can enjoy the introduction with music, but cannot start the game. The title screen reacts to no input by joystick, mouse or keyboard. I need to learn more about PC-98 using an emulator, I guess.

Me I used the one from Mame and the same tool to convert my floppies.
I tested my D88 on Mame and it is working.
I can used my game controller and go in game.

@wark91,
Thanks for coming back to me.
Yes I am using vfic ver 0.73.
I haven't actually checked it with a PC 98 emulator.
I only get a blank screen with no messages at all.
Thanks!

@mapf,
Thanks for your help as well!
Yes I have used the same software as mentioned in my previous post in response to wark91.
In fact I have used the same "Neo Kobe" archive. I will try it again just in case the file got somehow corrupted.
I am so jealous you guys got it working
Well, time to start from scratch then and will report back here..hopefully with good news!
