Mednafen PCE FAST : PCE CD Games nor working on pi2

Libretro Lakka
#1

Hey all, firstly thanks to the authors of libretro, retroarch and lakka. (first post)

So I’m having problems loading any PC Engine CDs with lakka specifically on r-pi2.

Bios is present, and works on other systems, like the windows retroarch builds. It seems like something has gone wrong with lakka or the pi builds? it’ll work with PCE roms btws.

Anyone else having this problem, or is it just me? Is it a know bug perhaps?

Thanks for your time. Love Lakka!

I have not tried PCE CD/SCD as of yet but I shall test tomorrow and post my results.

#3

Firstly I am using an old build of Lakka so might not be relevant now but I get the same result I can not launch any CD Rom game.

The .bin is not even shown in PC Engine xmb only .cue file.

I should update and try again.

Yes, you need the .cue file, mednafen is like this.

And you need the pce cd bios. If you don’t have this bios in your system directory, it won’t launch.

#5

Yeah that’s the thing, the syscard3.pce rom/bios is present as reported by the system info upon selecting the core. The image files I’m using are .bin & .cue files, and work on other platforms, like Mednafen PCE on windows retroarch. I’m flagging this up as it seems to be specific to the raspberry pi2 build of Lakka? I should also state I’m using the newest nightly of Lakka. Is anyone else capable of booting PCE CD games in Lakka on the pi 2?

#6

Ah, let me check this.

#7

Thanks for your time.

#8

I get a segfault when launching a pce cd rom on arm yes, let me see if the build of mednafen-pce is outdated.

#9

I’m can run Castlevania for PCE-CD on the RPi2.

However, I’m running the latest development version of Lakka, with an updated pce core.

Let me upload that version.

But I think your problem comes from a configuration issue, or a wrong rom.

Okay thanks for looking in to this. I guess I don’t refresh my config files between versions, so I guess that’s causing the issue, I’ll have to test it out when I get some time. Thanks again for looking in to this, keep up the fantastic work!

Ok! Found a bit of time to experiment with this today. Issue was, the cue files for my PCE-CD isos were referring to the iso in caps. I had to manually change the reference to the .iso file to be case sensitive within the .cue. So anyone else having this problem, open your cue files in a text editor and check its case sensitive.

I’m assuming I didn’t have this issue on windows because of the way the file systems differ?

I wouldn’t go as far to call this a bug, but it might be a nice if this is accounted for in lakka, or some kind of error message pops up.

I can only imagine how time constrained the devs are, so I totally understand that is isn’t accounted for, but I thought I’d update this thread in case anyone else has the same issue.

#12

You’re right, windows filesystems are case insensitive.

I don’t really see how this error could be detected.

Maybe we should just use an windows filesystem instead of ext4 for the storage.

I don’t know the side effects it could have.

#13

Here is a fix;

  1. mount the .cue with DAEMON TOOLS
  2. started up IMGBURN 3, select “CREATE IMAGE FROM DISC”, selecting the virtual drive,go!
  3. uste the IMAGE.CUE and IMAGE.BIN to play!

this made ALL turbografx-cds work for me…

hope this is in any way still interesting for you :slight_smile:
