This is a thread for the long running series of NEC PC-98xx computers line (and that, for the five people that lives on Mars, is definitely the most famous JP computer ever created, and that's not an understatement).
As usual, the topic is all about bug reporting and bragging about how the emulation is wonderful laugh

What kind of HDD interface do they have?

Edit: Just tried a couple of the non-working ones. The RX tries to use 386 instructions so either it's the wrong ROM or the wrong CPU. The UX is more interesting. It expects to read 0x80 from port 0x35 or it tries to do a reset to real mode jump, probably for Windows. Then it prints "SYSTEM SHUTDOWN". You can get past that too then it prints "A20 ADDRESS ERROR".

Either SASI or SCSI, it depends on the kind of the machine.

Additionally, PC-9821 has an undumped/unavailable IDE rom, if I'm reading NekoProject / QEMU source correctly they basically hack the space by filling some data I believe.

Actually, PC-9821 seems to work fine now (maybe due of the RTC fixes, no idea). Panic Bomber being one of the exclusive games halts with this:

Preliminary support for 256 colors mode:







Beware: PC-9821 is VERY intensive performance wise (~30% here).

Kanji hook-up tied to the CG ports. Next up:
*Do the bitswap at driver init
*Extract the missing kanji data from the hand-crafted ROMs (I obviously want a redump, but I fear it's unlikely)
