lr-np2kai Question Regarding PC-9801

@zering How do you go about that? My apologies, I'm not exactly an expert user.

@mcjones9631 No worries at all. Install WinSCP on your computer, then log into the pi using WinSCP. The login will probably be pi, thr password raspberry.
From there, launch your pc98 game. You know the window that indicates that a game is launching? Press buttons to interrupt the process and select 'Launch with verbose log'.
The game will fail to boot, as expected. In WinSCP go into the root directory, then dev, then shm. You'll find a file named runcommand.log.
If its not there, refresh. If it is, copy the contents to paste bin and share the link here.

@zering My WinSCP decided to not connect this morning, so here's the log straight off the Pi.

@mcjones9631 Hmmm I'm no expert but if I'm reading this correctly your installation just can't find your core. I suggest you try reinstalling the core from source.

@Folly Any ideas?

McJones9631

@zering Reinstalling the core now! Let's hope that was the issue. Thanks for the help!

McJones9631

@zering Well, slight problem. I got an error message midway through installation, reading "Could not successfully build lr-np2kai - PC98 emu Modified Neko Project II port for libretro (/home/pi/RetroPie-Setup/tmp/build/lr-np2kai/sdl2/np2kai_libretro.so not found).

Zering

@mcjones9631 Is it possible that the same message appeared when you first installed the core and did not notice it?

McJones9631

@zering I don't think so? It's had me go through a bunch of error log information about it, I would've remembered that thinking I screwed something up somehow. I just tried installing it from binary and it appears to have installed fine somehow that way.

Zering

@mcjones9631 Now that you've reinstalled from binary is there any change when you try to start a game?

McJones9631

@zering It booted up fine, I thought for a second I didn't have any controls but I guess I needed a keyboard and not my arcade controls oops. Runs really slowly but it works! Thanks for the help!

Zering

@mcjones9631 Nope, PC98 games were played with controllers for the most part. You can adjust that setting in the Retroarch menu. Likewise for speed, the CPU Clock Multiplier makes a significant difference. But for full-speed PC98 emulation you'll need a Pi 4.
I suggest you look at the Old Computer Appreciation thread in General discussion, there's a wealth of information on the PC98 there. We've discussed it a fair bit so feel free to ask any questions.

I read it.
So it seems to be fixed with the binary install.

Perhaps you had a bad internet connection while updating the packages for installing the source.

Did you have a crash while updating ?

Try to update/upgrade your pi with apt.
If all goes well you can try to install the source again.
