How do i setup PCFX?

markwkidd

@backstander thanks for writing about that. I'm not by any means well acquainted with this code, but I think the change is straightforward. I just filed a pull request which hopefully the librero devs will act on or respond to.

If you want to keep an eye on the PR, here's the link: https://github.com/libretro/beetle-pcfx-libretro/pull/16

@backstander OK that next change was just merged into the PC-FX core. If you have an opportunity, could you rebuild the core and see if it eliminated the sound issue on your end?

@markwkidd
When you ask me to "rebuild the core" are you talking about rebuilding lr-beetle-pcfx/mednafen_pcfx_libretro.so from source?

I just rebuilt source and it is still shuttering sound but it feels a little bit faster. Like before it was playing at about 75-80% full speed and now it feels like 85-90% full speed.

@backstander That's disappointing to hear about the audio. With regard to your question, yes, I think we are talking about the same thing. I'm not familiar with the build processes available to retropie so I wound up writing it vaguely.

The github source for lr-beetle-pcfx/mednafen_pcfx_libretro was just changed with a second patch about three hours ago. If you've downloaded that github source since then, compiled it, and are still experiencing audio problems I'd like to encourage you to post an "Issue" in the tracker for that core: https://github.com/libretro/beetle-pcfx-libretro/issues

I'm mostly a scripter and documenter. I've been able to make a couple of small fixes to the core but it will be necessary to attract a more experienced libretro developer to take other steps on the audio issue from here. Thank you for your help so far. Your bug report could also be very helpful in the form of an issue! :)

I started a PC-FX page on the official RetroPie Wiki
https://github.com/RetroPie/RetroPie-Setup/wiki/PC-FX

I don't know how to put it under Emulators and I'm not good at graphics so it still needs a logo banner and the controller configuration picture but at least it's a start.

I also filed a PR for PC-FX artwork in the Carbon Theme
https://github.com/RetroPie/es-theme-carbon/pull/24

@backstander earlier today another developer added a variety of new "core options" to the libretro Mednafen PC-FX core that allow the various settings from Mednafen to be set for the libretro version.

If you look at the Mednafen docs, several of these options seem to relate to performance: https://mednafen.github.io/documentation/pcfx.html#Section_firmware_bios

I don't have an rPi2 so I don't know if it is worth time investigating, but I wanted to let you know in case this might help get emulation running faster on your hardware.

Is this core still working? I have installed it today with some games and the right bios but none of the games open and checking the logs looks like an emulator issue:
/opt/retropie/supplementary/runcommand/runcommand.sh: line 961: 4393 Segmentation fault

I updated from source and ran it about 3 days ago and it was still running. The source might be broken at the moment. I'd recommend trying compiling again from source either later today or tomorrow.

but none of the games open

Which games are you trying?

I've only tested 3 games and these 3 worked for me:
Chip Chan Kick
Dragon Knight IV
Return to Zork

@backstander looks like is an issues with the game I want to play, Kishin Douji Zenki FX Vajura Fight. Is working with Chip Chan Kick

backstander

@Tasio
Kishin Douji Zenki FX Vajura Fight looks like a cool game so I decided to give it a try! It sames to work for me but slow motion like all the other games I've tried. I had to edit the .cue file. It was the correct name but had the wrong case. Remember: Linux file names are case sensitive.

@backstander thanks it was my issue too, the extension (.BIN) was in different case. Now is working but has you said, it's slow, I have tried at 240 but still slow, hopefully will get better with future releases.

I sure hope so too! I think they are on version 0.9.42 so maybe it will be more optimized when they hit that version 1.0 ;-)

I think I'm going to try to put this PC-FX banner on the Wiki

@backstander missing the hardware but otherwise looks good

@backstander i would love to have this running full speed. I have had a complete set for years hoping to be able to play them one year. Looks like a lot of cool japanese anime games on the pc-fx. Way too slow at the moment on the pi.

backstander

@edmaul69
I have wanted to try this out on a PC running x86 Ubuntu but have been way too busy this summer but I would also love to have it running full speed on a Pi. Hopefully one day on the Raspberry Pi 5 we'll be able to get it working full speed ;-)

Doh! If I find a good hardware shot I'll update it but it could be another 5 months lol
I like this PC-FX graphic because it is a good quality PNG with a transparent background

@backstander no worries, I've never used it myself anyhow :p
