But early models, with Nec V30 CPU, are poorly documented on their bus (other than C-BUS), vidéo chip, and ram upgrade. For example, the range of PC-9801V / VM / U / UV / UX has no documentation on how to upgrade it.

There is some slots on motherboard. One is used for sound card and it's "not" C-BUS but more like than a large grey IDC connector. Is this...

The PC-88 series was a fairly powerful Z80 based machine but NEC wanted to push into the 16bit business PC market and made the PC-9801 series in 1982. These machines ran a NEC made 8086 and had a 640x400 mode in 8 colouirs with later machines using a V30 and offering 16 colours from a palette of 4096 colours and then the 286, 386 and 486 series...

This isn't game related but rather software used in Japan's motorsport.

I recently bought an dedicated EPROM pogrammer to reprogram the ECU of my car. When it arrived it came with 4 3.5" floppy's and a manual stating I need either a NEC PC9801 or EPSON PC286 to use the included software. After googling these terms and...

I got interested, but it's fully japanese (oh really) and I can't read japanese. I played it in PC-8801 and I got as far as finding the menu to disable music. But I've heard that you can use Anime Text Hooker on PC to translate it on-the-fly. I'm going to try it, but I also came across this page:

It works on Anex86 but Anex86 does not have s98 logging.

What other Emulators have s98 logging?

How i can contact to developers of any emulator?

Is the PC98 version even worth any hassle to try and emulate? Has it been dumped to check out? I don't know much about finding these roms.
Odd seeing an already underrated FC/SFC game get such a relative.
