L4T Lakka Switch - now with audio and Vulkan

EmulateLife · Aug 9, 2019

I'll ask again has anyone tried NAOMI games personally, and got them to work on Lakka? Arcade games that use .zip format, but there was some implementation on PC with Reicast of them.

Anyway I'm going to try myself I guess by reinstalling the older Lakka but I just am not 100% sure if I have the bios named right etc... Naomi needs seperate bios from dreamcast games.

Just took the time to re-install the older Lakka and Naomi games still failed to load content.

What? Are you sure? Do you know what I'm referring to when I say Naomi games? They're arcade games made by Sega, they come in .zip format. You're saying on the previous Lakka of Reicast they worked?

When I try on Flycast I get failed to load content.

EmulateLife said:
Ok so you're just guessing. There's one person saying it worked on Reicast, I'm still not sure if that's true or not.

I know what Naomi is, and I'm not lying about getting it working. I'd offer you a few things to try, but you probably wouldn't believe me.

Can now confirm they run fine. It might have been a guess before but its pretty calculated when in the update they say “the core has been renamed flycast” and it mentions no drastic changes. The only reason i have had the core not work is
1) retroarch.cfg is corrupt
2) core options has been corrupted for dc(a setting games dont like)
3) gl or glcore is not the selected driver
4) your DC Bios dont match the directory menu(if DC folder is in system, select system as your BIOS folder, dont select system/BIOS!).

I'll try it thanks.

I don't think it's corrupt because I just reinstalled both the old and new Lakka, but I'll try it.I tried gl and glcore still failed to load content. I tried storage/system and I have naomi.zip and naomi_boot.bin both outside and inside DC folder, still failed to load content.

Deleted retroarch.cfg and retroarch-core.cfg no change.

Under main settings core information it shows

(!) Present, Required: dc_boot.bin (Dreamcast BIOS)
(!) Present, Required: dc_flash.bin (Date/Time/Language)
(!) Present, Required: naomi.zip (NAOMI Bios from MAME)

So it is detecting the bios. I'm going to try other games and see if it's just the game I wanted to work that's the problem.

Yeah there might be some problem with the game I was trying to play Virtua NBA, Crazy Taxi works for me. Thanks Basketto for the help.

I believe this is how to get the game to work, but I don't understand it or how to do it.

https://forums.libretro.com/t/cant-figure-out-lst-files-for-reicast-not-loading-reicast/16705/8

Figured it out! I guess this game needs to be in a different format as talked about in the above link, I found 1st files and VirtuaNBA.bin, now I'm rocking, and it does work on Flycast.

I'm going to try it on Reicast on Horizon now, if Naomi works on it it could fix a lot of games there that are messed up (Marvel vs Capcom 2 etc...)

Edit: doesn't seem to work on horizon Reicast oh well.

Does anyone know for Wii games can you import saves from a Wii (actually vWii on Wii U) and then have it work on Dolphin Lakka? I assume it might involve sending the save through Dolphin on PC.

Main thing is change the emulated clock speed, but you can try experimenting with other settings aswell. Then of course I would bump your CPU to around Max performance. For most GC games it should be enough.

For Super Paper Mario I think you need to enable BBOX in the options. One of the things that got added in the latest build which fixes a few games .

New Super Mario Bros Wii will go at full speed(1768cpu), and so does Klonoa(requires maximum CPU
& requires vsync off. For some reason Mario Bros works better with GL/GLcore as your main driver over Vulkan).

Anything else you did on New Super Mario Bros? I am on latest Lakka, have it at 1768cpu, tried gl and glcore, but it is very very slow.

Or were you using the older version of Lakka?

EmulateLife · Aug 10, 2019

Got New Super Mario Bros Wii to work well with Vulkan + overclock, and another game Lost in Shadow same settings. Pretty cool game. The WBFS is only a little over 1 gb, it seems smaller games seem to work large games don't.

I was indeed using the older version

. Im glad you have it running well with Vulkan though! I found this tuturial on 1st files(hopefully it may help) I haven't tried many naoimi games and I haven't tested it myself but hopefully it will get virtua nba going. I believe for lakka they would just go in the same file as the games. However hopefully this helps somewhat.

If we could do dock and pro controller support + a way to boot into this and back through Horizon aka without going through RCM twice this would be golden!

That has been said for ages lol

. Personally I would be more than happy for just Pro controller support even wired. The thing is, as Natinusula mentions earlier in this thread, the controller mappings are hard coded into Retroarch and a workaround would have to be solved as plugging another controller in would make Joycons unusable.
Idk what progress has been made, or possibly an option could be added later with "Reboot to Wired/wireless controller" to switch configurations between the two modes from the retroarch menu. As far as I know though for bluetooth wireless controller support no breakthroughs have been made. I can always hope I am wrong though

I believe I now have all Naomi games working but some games need to be in a different format called .lst I got Virtua nba and samba de amigo working in that format. Those same games did not work for me in .zip format, and I'm using the new Lakka.

I know it probably won't work very well anyway but wanted to mess with settings on Skyward Sword but I can't figure out how to get it to think I have MotionPlus to get past that screen has anyone been able to?

I got another Wii game to work Zack and Wiki Quest for Babaros Treasure, the problem is the motion controls makes it hard to play. Like you have to pull this lever and with the wiimote you're supposed to motion like you're pulling a lever and I can't figure it out using the right stick. Motion controls suck.

Super Paper Mario I overclocked enabled BBOX it always freezes at the same spot towards end of all the opening cutscenes.

For super paper mario only thing i can think of(setting wise) is try changing texture cache accuracy to safe. It is a longshot

but possibly could help with the freezing.

Didn't work still froze at the exact same spot, I'm thinking maybe it's because I'm using the new version of Lakka vs the old version. Oh well no biggie.

For Skyward Sword, I don't think Dolphin got MotionPlus emulation until very recently. The build used in Lakka might be an older one which doesn't have it implemented yet.

Retroarch cores are often outdated. It's the only downside really. I wish I could figure out how to compile my own cores.

I've been having a problem where all games on all cores crash out to the Retroarch menu after about 2-2.5 minutes of play. This was on the previous May version and now the new July version after a full re-install.

This includes MAME2010 and Dreamcast games.

I have a 400GB Sandisk card formatted using guiformat.exe

It's odd as games do work for a couple of minutes so I'm not sure if I've missed something or maybe it's a permissions thing or Retroarch is trying to write to a folder that doesn't exist after a certain time? All of the issues I've read in here with cards relate to Lakka not booting at all. I'm opening the games by load content then selecting the core.

Did you solved it?
That has been my problem since the beginning of Lakka, I even tried older versions, on 3 different sd cards many times, of course fat32 and good normal installation, but always after 2-3 minutes of playing GC games, it exits to the main menu of Lakka.
One second before that the screen goes black and a little cross appears (like the windows closing icon).
Anyone knows why? Can I search for the reason on some log file? Because it's very weird, I have no problem with any other Homebrew or scene thing, except lakka and Linux.
