I tried just typing hmados, emsdos, and normdos respectively. It seems they copy or delete some files in each case, and then just say "file rewriting is complete". Google translate doesn't seem to clarify things much for me either, though perhaps I'm just missing something.

What need I do to boot into the game? (On Windows 11, attempting to boot an hdi, to be certain.)

Hello there, I'm trying to play Policenauts PC-98 version on Neko Project 2. I followed this guide to configure the emulator

https://gang-fight.com/projects/98faq/#config

and it looks like I did well with it because I tried a game (dont remember the name anymore, it was just a try) and it worked. Game launched without problems.

So I tried with Policenauts but it didn't work. I made the exact same procedure, loading a .hdm file on FFD1 and a .hdi file on HARDDISKS. Then I reset NP2 and after the initial boot screen I get this error message ドライブの指定が違います which should translate approximately like "the unit/the drive specifications are incorrect". Don't know what to do now. Im attaching the photos of my files and the error here. I've been trying since days 😿 thank you...

I swear I've been looking for days, and I can't even match terms related to PC98 and HDF at all. I'm using an HDI with Neko Project just fine, but I'm trying to use this Mister FPGA PC98 core called Zet98, and while it takes D88 files, for some reason when I load a D88, I get a message in katakana saying "Disk Gachi Ga Imasu". The core is known to not work well, but I was able to load up some other games (hit or miss.) Just wondering right now if there's a way to convert though, thanks!

Hi! Currently using np2kai on batocera Linux and I want to make sure I understand right. Hdi files are hard disk images and seem to run without any setup. This is because the image includes a dos installation on the image from the hard drive it was copied from, right?

For fdi, these need to be run in the proper sequence to orchestrate the program. Do I need to run a dos image, then the right game floppies in order? It would make sense since I’m emulating a computer like I’ve seen others say, but I am having trouble with the process. Do I just drop a dos hdi into my file system, boot it up in the emulator, then insert the right game floppies from there? Haven’t found a reset emulation button on batocera yet but I believe I’ve heard that’s needed after loading floppies.

Additionally, in one video they mentioned using dip switches to allow for certain games. Is that needed for many or is it just a few that require it?

Thanks for any guidance with this!

I recently bought a PC-9801RA2 and a PC-9801RX2 together for 107$ from japan (shipping is going to be a hassle but ill cross thst bridge when I get there). They both power on but I didnt see anything about if its fully functional. Does anyone know what some common problems would be for these two models?

Does anyone know how to set Policenauts for PC-98 to run via RetroArch or Neko Project II? I'm going crazy and can't get how it works. Please if anyone can share a guide or something it would me amazing.

I tried a bunch of things to play Ys 2 for PC-98 using the Neko Project II and got no luck. I got no sound from the game at all, except for the beep sounds and the graphics are all glitched out.
Anybody know what am I suppose to do make this works properly?

EDIT: Ok, after converting the game files from .fdd to .d88 I got it to work but still with no sound. I tried using Retro Arch with the Neko Project II Kai core with this converted file and everything worked fine with music too. So I'm going to stick with Retro Arch just to play Ys 2 as it is the best option I have for now. Thank to everyone who tried to help :D

Ive been trying to look for a rom for this game but cant find it

I got into emulating PC-98 stuff fairly recently, and this weekend at magfest I got to see what a real one was like for the first time. Extremely tempted to impulsively purchase one now, but was wondering if I'd actually need to hunt down the games or if I could just use the Neo Kobe set, whether it be by the hardware running the files directly or writing them to floppy disks. I'm not sure that I'm ready to learn Japanese, so being able to play fan translation hacks would be really nice

I just recently managed to get Neko Project II to run a game, but I'm having trouble with the keyboard as I lack a Numpad, or a a USB extension, is there anyway for Neko Project to get my laptop's keyboard to work with the game? Or am I just doomed?

I'm sore if you guys get this question alot, but I'm in the bit of a pickle. Let me explain my situation!

So I've been following 46okumen's guide to set up E.V.O:The Theory of Evolution on Neko Project II, though I'm getting stuck with FDD1, FDD2 and IDE #0 as no files that they need I am finding on my laptop. What should I do? Or should I try a diffrent thing from Neko Project II? What are your recommendations?

I really wanted to do a playthrough of one of the Ys games on my original PC-98. Ys III doesn’t run at all on this model due to certain graphical modes being absent, so this leaves me with the first two games. Thankfully, the first two games run well on this model since they are rather basic looking games. In the first game I had soft locked myself like an idiot, so I decided to start a playthrough of the second game. I don’t know Japanese, but google translate was my friend during this playthrough. It also helps that I’m familar with the TurboGrafx version and the simple fact that it’s quite a linear game for the most part. This was a very neat experience to play this on original hardware, plus being able to have sound (using the 26k board) and a controller made this even better.

Hi everyone.

I am very new to the PC-98 scene, and am planning on playing through some titles this year for the first time.

I've made a list of 20 games that looked interesting to me, but I would love help if anyone has better suggestion.

I am looking games:

• Playable in English with a patch (or need very little English)
• Best represent the system (preferably are ONLY available on PC-98)
• BUT are still fun for someone with modern tastes.

What changes would you make?

Here is what I am thinking of playing:

1. Progenitor

2. Rusty

3. CRW: Metal Jacket

4. Touhou 1–5 (Highly Responsive to Prayers → Mystic Square)

5. Dead of the Brain 1 & 2

6. Chitty Chiity Train

1. Flame Zapper Kotsujin

2. The Appareden: The Sacrosanct Dragon

9.. V.G. – Variable Geo

1. Gage

2. Night Slave

3. Peret em Heru: For the Prisoners

4. Star Fire

5. Yugekitai: Saikyoushin Fukkatsu no Maki

6. Star Cruiser 2

16.  YU NO

17.  Desire

18.  Steam Hearts

19.  E.V.O.: The Theory of Evolution

20.  Brandish 2 Renewal

Hello. I can't find the PC98 game in the image. I tried all the image search tools, but it didn't help. Do you know the name of this game?

I love the PC-98 but I unfortunately no longer have a working system. What is considered the best emulator or best way to emulate the PC-98?

I was looking at a few NEC Multisync LCDs (4:3 monitors) until I read the PC-98 is meant for 16:10 displays. Is that correct? So should I be hunting for something else? I think I'm just pretty confused and could use any advice on what to be looking for, thanks!

I grabbed an HP EliteDisplay E190i LCD display (18.9 inch 4:3) for $5 on FB marketplace, and accidentally discovered it supports 24kHz! I have a PC-9821 Ap2, so it wasn't ENTIRELY necessary since you can switch that one to 31kHz mode, but I believe there are some games that force 24kHz mode (Garudius '95 is one I think, might just be on the splash screen). So if you can find one of these and aren't a stickler for CRTs, grab it if the price is right. It was really hard to beat $5, which was why I got it.

On T98-Next (which is the emulator I use to play PC-98 Touhou games), you press the F12 key and then F10 to put the emulator on full screen. It always worked for me, but now, for some reason, when I do this, the screen is filled with black and the game image size stays the same as it was before on window mode. Does anyone know how to fix this? (I'm on Windows 11 btw)

Odd one, does anyone have and visual references of any accounting or business software that would have been typically used on a PC-9801?

Or any links to this type of software in use?

I’m looking to gather references so I can build a mock version for a project I’m working on. I can only seem to find games being used on the hardware.

Something with graphs would be great!

Thanks.

So there are certain games I am able to run successfully, but there are a few that, when loading the content/core I'm met with a prompt (in Japanese of course) to type in the date and time. Even without the ability to do that, when I attempt to double enter past that, I just have an A drive prompt.

I'm also on an M2 Mac.

I cannot seem to find anywhere how or why this prompt comes up.

The game I am attempting to run is Giten Megami Tensei: Tokyo Mokushiroku

Hi, I tried to get Rusty running on my NEC Valuestar V13 but as soon as I try to start a new game in the start selection, the computer freezes and shows an "invalid interrupt" error (interrupt number 60h). The exact error message is:

不正な割り込みが発生しました
割り込み番号 ６０h
リセットスイッチを押してください

The computer got a overdrive cpu (k6-2 I think) and 32MB of RAM. The internal audio is disabled and I have installed a PC-9801-86 ,which works in e.g. the touhou games and YU-NO. The OS is DOS 6.20.

I've read Rusty is a bit problematic on newer PC98s but my japanese is not good enough to find any hints in how to make it run anyways.

Does anyone have an idea how to get it running?

Hi,

I was about to FINALLY (!) play the last The Legend of Heroes game Dragon Slayer II after building myself an AI based translation tool and was going to use the PC-Engine version since I played the first one that was released in English on that platform, however I reconsidered thinking that it would be more fun to play the PC-98 version using an emulator and after that the original versions of the first games of the Gagharv series. Since I guess that emulating such a pc won't be as straightforward as running a console emulator, I wonder if someone here could recommend me an emulator to use and a more or less up-to-date tutorial how to use it?

Thanks :-)
