The "some reason" is:

"Already operating in virtual 68 mode"

I guess the DX386 DOS extender doesn't like EMM386 (or whatever the PC98 uses instead for EMS)

The f.com file is apparently only for the EPSON PC Series

I don't have anything to contribute, other than, thank you for sharing that info. Later systems like the PC-98 or even regular PCs had no end of compatibility issues, and having confirmation of a game being unstable is intensely helpful for anyone working on emulating such systems, so they don't spend a lot of time trying to solve weird bugs that actually happened on real hardware. MAME could definitely benefit from more people like you. smile

Actually it wants a serial number in the top field. The serial number was apparently written/printed on a "user registration card"

No prob, my PC-9821Nw150 is always available to anyone who wants to test anything on real HW. I don't have any older models to test, though. I only got that one because, being a laptop, I could get it sent to me from Japan more or less cheaply. That, and it's one of the last models with an actual FM synth. smile

By the way, I tried again and now I remember what happened: Policenauts requires the AVSDRV.SYS PCM driver, but it has to be a version that works with your specific hardware (I remember having to search everywhere for one that worked with the Nw150), and I couldn't find any that worked with MAME. So in the end I always get something like this:



Which would be something like "the PCM driver AVGSDRV.SYS isn't installed".

Looks like shattered PPI change at https://github.com/mamedev/mame/pull/1950 broke the 9821 detecting ram over 640K (more correctly it fails to read the dip that shows that there is more ram). It sets the mouse ppi control to 0x93 which is port c upper output and lower input. I don't really know enough about how it's supposed to work in that case to fix it.

Edit: If the above is changed to
Code:
		if (port_c_upper_mode() == MODE_OUTPUT)
		{
			// read data from output latch
			data |= m_output[PORT_C] & mask & 0xf0;
		}

the it works again. Don't know how that effects the Displaywriter though.

WRT doom

Use "-cbus0 pc9801_86" for PCM audio and "-ramsize 14M" otherwise it'll fail with not enough ram. Also, disable HSB.SYS if you are using an HDD image with it.

That was easy to nail:


It hangs here for 98RS tho.

Actually happens for all Nazo Puyos from Disc Stations (9, 10, 11), and yeah it's an error frown

I guess PC-6001 needs to be checked out, it still uses an hack for ppi port(s)
