Injecting BIOS & ROMS using Ethernet Cable OR SCP / Filezilla methods

Libretro Lakka
#21

PSX BIOS were correct. I’ll add to the ROMS/BIOS page the md5sums and also software used with screenshots - in this way all necessary info will be in one place without sending users to pages outside Lakka.tv

PSP - I am having difficulty with SSH, can I instead use the Log settings from within Lakka? There are options: 0, 1, 2 - which one should I use? Thanks!

Also, I checked the folders having cores in their names and all came up empty (both using SysInternals and Mounting on Linux). Could this be the case? That I do not have any cores? Please refer to this link: here.

#22

Thank you for consolidating the documentation on lakka.

Did you check the cue file ?

Did you try to connect with ssh client kitty or direct acces to get the log ? You need to get access to the command line to get the log.

Cores should be in /tmp/cores

#23

You’re welcome.

Doc Update

I added the md5 sums but on next website-refresh, we’ll have to check that the table is displayed correctly.

In the meantime I added as TODOs the screenshots as procedures for checking the sums, I can definitely do the Windows part, and most probably the Linux, but Mac… no experience with macs.

Troubleshooting

PSX - Cue files were correct. However, PSX was not working because I placed the BIOSs in the assets folder instead of the system. Now PSX emulation works, however, I do not have any sound output. I’ll do more testing and if I cannot manage I’ll produce a log.

PSP - placed ppge_atlas.zim in the system folder along with flash0 - which includes the fonts from PPSSPP. flash0 is not in the documentation. Info about flash0. Thus, if you deem that flash0 is necessary I will add a reference in the doc. With all that said, PSP emulation is not working. Following is the log (thanks for pointing me on how to do it): log.txt (14.6 KB)

Thank you.

I misread your post earlier, and I thought you were saying someone else needed to write the Windows MD5 instructions. Oops. I went ahead and added some.

We need to fix audio. Can you try this to get some information. If you have snd_hda_intel listed with lsmod,try this command.

#26

No, no, I hope you did not delete your work! Keep them :smiley:

OK, in the meantime I had already edited retroarch.cfg with sysdefault but haven’t tested it on the L-USB on the hardware. I’ll get back with solutions/errors.

BTW, aplay -L >> aplay.txt makes life easier esp. when mounting on another Linux.

#27

Audio is fixed. I did not use the lsmod | grep snd command, instead, when straight to aplay -L >> aplay.txtand from the output list chose the sound that had sysdefault. It worked immediately. If you need me to run lsmod | grep snd , I’ll comply.

However, I am still stuck with the PSP fault. Any thoughts? The log was provided as requested.

#28

Yes, it will be helpful if we have the output of lsmod | grep snd.

So it is not because the audio issue that PPSSPP segfaults. Maybe you are missing some file from assets ?

#29

lsmod[I] | grep [B]snd

[/B][/I]lsmod grep snd.txt (527 Bytes)

aplay -L

aplay.txt (1.16 KB)

My Solution

retroarch.cfg --> audio_device = “sysdefault:CARD=Generic_1”

No, the no-sound issue is not the case because on selecting a PSP game I get a black screen and then Lakka’s screen.

/storage\system\PPSSPP\ contains: folder- flash0 file- ppge_atlas.zim

Shall I add all the files provided in the link in [I]/storage\system\PPSSPP[/I] ?

UPDATE: I injected [I]/storage\system\PPSSPP[/I] with the contents of the libretro-ppsspp link provided. On rebooting Lakka, and selecting a PSP game, it worked. However, on L3+R3, reset, and selecting the game once again, I got the black screen and then the Lakka screen.

#30

If you do this, you shouldn’t have to edit retroarch.cfg for audio. You can change audio device in the gui.

I don’t know how to fix the reset issue. You reproduce it with other games or only with psp games ?

#31

Before doing the suggested command, I had no other options in Audio Devices except for ‘sysdefault…’ which became available when I had edited retroarch.cfg.

On implementing echo “options snd_hda_intel index=-2” > /storage/.config/modprobe.d/snd_intel_hda.conf and rebooting, YES, I had the other devices listed in aplay -L available for choosing.

No, only with PSP games. I’ll experiment more on this issue.
