There’s no option to make the mouse slower, it would be great to have one in Retroarch itself.
I’ve got a mouse with physical DPI switching buttons to make it slower here.
Try using “Joypad to Mouse Mapping” option to move the cursor with the gamepad if that’s better for you.
Found the issue: I had to switch “user 1 mouse index” in the input configuration in Retroarch from #1 to #2 and also turned off both joypad to mouse and joypad to keyboard mappings in the core options. Now mouse speed is fine in F12 menu.
Thank you both for your help! Looking forward to using this core!
I don’t think Vsync / No Wait / FrameSkip do anything at all in Core Options.
This is handled by Retroarch (except the frameskip which is not possible by design i believe).
Yeah. I think you saying too.
Those options are no effective…
It is fixed 56.4fps.
I hope to use ‘No Wait’ option with this core.
By the way, I check NP2kai core’s running and fmgen sound, Joy2Key by Touhou 2.
It was fun! 
edit: I can control speed with ''Frame Throttole" and R.Alt key,
“Slow motion” and e key. That’s enough.
edit2: I removed frame control options (No Wait, Frame skip, VSync).
Great score! 
I only finished it once with 3 continues for now.
I need to practice those games more.
Talking a bit about that game “Miko-san Fight” as it seems many people are confused with its gameplay mechanics.
On the right side of the screen it shows you which scroll color kills which monster.
Only the most recent scroll you picked up (the one on the right end in that bottom bar) is active.
To effectively kill a monster you then have to touch it while facing it (don’t stay facing the camera, can’t kill while climbing ladder…).
So it’s like a puzzle-platformer: pick up the scrolls in the right order, sometimes jump above the monsters, find a way around the levels that works…
A CPU speed around 33Mhz seems right (x12)?
Joy2Key on “Keypad” is needed for this game to play with a gamepad.
Supplement.
Initially, PC-98(PC-9801/PC-9821) is derivation of PC/AT with MS-DOS.
PC-98 have BIOS.
It can be setup with End key(Help key) + power up.
GDC clock can be set to 2.5MHz/5MHz.
CD drive can be used with NECCDD.SYS and MSCDEX.EXE.
Hi.
I fixed BEEP PCM.
I checked it in the ‘2 Shot Diary / ツーショットDiary’.
But other game isn’t checked yet.
(‘2 Shot Diary 2’, ‘TOKIO’, etc)
BEEP may sound strange.
Please try this.
Hi, thanks for your effort on this issue.
It’s better than before, voice is clearer, but pitch and timing seem wrong.
(It seems that it has nothing to do with my BEEP PCM betterment.)
I’ll search this problem.
Speaking of issues, I spotted a problem with the core not reading in core overrides and shader setting when loading a file via Load Content (at least for the first time you open a file).
If you open by “Open Recent” it seems to load ok.
That’s a problem happening with DosBox too.
@Guicrith is the one who ported those cores and I think he omitted something, but I’m too bad to figure out what it is myself. 
It looks like standard NP2 is loading correctly so I’ll try comparing them to see if anything pops out. I am 99.999% sure that your a better coder than me though so don’t get your hopes up.
I think it has the same problem.
Seeing that it works with a playlists entry, it’s probably because it got a path or the core name with it that is missing otherwise when doing “load content”.
Figured it out (at least as far as I can tell) then spent an hour trying to figure out github. Anywho, the issue is in libretro.c – there are two spots in I think in retro_set_environment where it’s trying to allow booting without a rom specified. If you delete those portions it auto loads the settings correctly.
I’m not sure when I’ll have time to figure out git and commit though.
Nice, I can confirm that.
But this call allows the core to be started without content, so removing it is not the best solution.
I’ll pass the word around to see if that’s something that can be fixed at Retroarch level.
I implemented booting without a rom specified for using as real PC.
But full key is inconvenience on RetroArch.
Then, I think setting ‘RETRO_ENVIRONMENT_SET_SUPPORT_NO_GAME’
is not important.
Let’s wait Tetsuya’s betterment.
Or please tell me, when I have to remove ‘SET_SUPPORT_NO_GAME’.
Sorry to inconvenience. Thanks.
Np2kai is in the buildbot now for most platforms (still missing some like android x86/arm64).
You can get it by going into the Online Updater, updating core info files, then download the core.
I checked NP2kai, T98-Next, and real machine.
They occurs Garudius95 title image is missing 16 pixels on bottom.
It’s displaing is beautiful on Anex86 (emulation EPSON PC not PC-98).
I feel wasteful.
edit:
Oh, sorry. I don’t want to say ‘waste’. Bad word.
I wanted to say how can display correctly image like as Anex86.
Probably real PC-98 display image not correctly too.
Let’s call NEC.
They need to fix their original machine then. 
(…or Garudius 95 authors.)
