(libretro) Problems with Disk Control #69

Closed orbea closed 3 years ago

orbea commented 5 years ago

OS: Slackware64-currnet NP2kai: https://github.com/AZO234/NP2kai/commit/e0b9fe55279e5d52df71c070a347c30ab3bf5c8b RetroArch: 1.7.7

I am trying the English translation of the game Farland Story as can be seen in the following link.

https://www.romhacking.net/translations/646/

This contains four fdi files.

Farland Story 1 (English)(TGL)(Disk A).fdi
Farland Story 1 (English)(TGL)(Disk B).fdi
Farland Story 1 (English)(TGL)(Disk C).fdi
Farland Story 1 (English)(TGL)(Disk D).fdi

If I load Disk A with the libretro core it loads correctly, but I get stuck when it asks me to change disks after starting a game, the Disk Control option in the RetroArch's quick menu is not available and I can not manually append disks.

The Disk Control option is available if I open a single file with other libretro cores like beetle-psx.

1

So I next added the four fdi files to a plain text m3u file.

$ cat Farland\ Story\ 1.m3u 
Farland Story 1 (English)(TGL)(Disk A).fdi
Farland Story 1 (English)(TGL)(Disk B).fdi
Farland Story 1 (English)(TGL)(Disk C).fdi
Farland Story 1 (English)(TGL)(Disk D).fdi

And if I launch this m3u file I notice a few issues.

  1. I get stuck on this screen directly after the memory loading screen and the game never starts. 2

  2. From stdout I notice its trying to load Disk B instead of Disk A, but even if I edit the m3u file to make Disk A the second item in the list it does not help.

    $ retroarch -L np2kai_libretro.so Farland\ Story\ 1.m3u 
arg_0:np2kai
arg_1: "/Farland Story 1 (English)(TGL)(Disk B).fdi"
Samples:782
INIT done

    Edit: The disk control option in RetroArch's quick menu is available if I load a m3u file, but it does not seem to help here.

Is there anything that can be done to make this game playable with the libretro NP2kai core?

I have not investigated it yet, but I have some advice.

NP2kai has two FDDs and is not made to have only one FDD. So, the first line of m3u mounts to FDD1, the second line mounts to FDD2, respectively.

"Option"-> 'Swap Disk on Drive' = FDD1 Have you tried the above settings?

About pic of after the memory loading screen. It is displayed when the boot of FDD fails if the BIOS of PC-98 is not correctly installed in RetroArch's system directory.

Thanks to your report.

I tried this setting now and it did not make a difference, the stdout when loading a m3u file still shows Disk B.

Yes, you are right. I did not have the bios files. I now added them and it now brings me to this screen when loading and m3u file.

I do not understand why it proceeds to load the game without bios files if I load the fdi file directly, but fails if load a m3u file?

AZO234 commented 5 years ago

There are other operations that use Joy2Mouse. "Option"-> "Joy2Mouse/Keyboard" = Mouse, then press joypad's L2 button to embedded menu. This menu can mount/eject FDD1/2.

We will continue to investigate the operation with RetroArch's menu.

Edit: Games boot with disks method is few kinds.

  1. A disk to FDD1 -> You can start a .hdi file. and swap FDD1 disk with L2 menu.
  2. A disk to FDD1, B disk to FDD2 -> You can start a .m3u file. and swap FDD1 disk with L2 menu, swap FDD2 disk with RA menu.
