[Release] Nec PC 9801 and PC 9821 emulator : NP2Kai
« on: June 10, 2020, 07:00:45 pm »
I compiled and tested NP2Kai emulator (http://domisan.sakura.ne.jp/article/np2kai/np2kai.html) for RG350.
It emulates this 1982 japaneese computer : PC 9801 and 9821 (https://fr.wikipedia.org/wiki/PC-98).

If you want to test it, you can get it on Github : https://github.com/goldmojo/NP2kai/releases
Original sources are available on its author Github : https://github.com/AZO234/NP2kai

BIOS files should locate in ~/.config/np2kai (or np21kai)

Hello @matsu_kakako

If you are always interested, I just optimized the emulator with some profiling.
Here is the new one : https://github.com/goldmojo/NP2kai/releases/tag/rev.22_rg350_r2

I need some help to choose a good key mapping. What would be the best mapping for you ?

I've tried this on my RG-350 with OpenDingux nightly beta, only found that the emulator starts with a black screen and a PC-98 boot chime, then it hangs.
Currently OpenDingux nightly used a newer kernel and GPU/IPU modules compared to older one I think.

I didn't compile it on the new OD beta for now but will do it soon.

Hey, the emulator runs perfectly on my PocketGo 2. I tried open Touhou 3, it boots up and shows some text. But after the boot up text, it won't open the game. Is it because i haven't put the BIOS?
When I try to put the BIOS, I still don't get the ~/.config/np2kai folder, where is it exactly? I find it anywhere but nowhere to be found.

Any help?

You need to create the .config/np2kai folder manually in your home directory.

PC98 bios is composed of this set of files :

2608_bd.wav
2608_hh.wav
2608_rim.wav
2608_sd.wav
2608_tom.wav
2608_top.wav
bios.rom
default.ttf
font.bmp
FONT.ROM
itf.rom
memory.bin
sound.rom

Then you should be able to run emulation.

Any tutorial on how to make the folder in home directory? I'm using Commander to create the folder but the folder doesn't seem to be created. I tried using WinSCP to create the folder but it keep saying access denied

I tried it on my rg350m, eveything works fine.
But is it possible to change the resolution to 640*400? Since rg350m has a 640*480 screen.

btw ,about the key mapping :
A = Space
B = Escape
X = Return
Y = Ctrl
would be a better setting in my opinion.
