    Have you tried the european (PAL) Mario Tennis? My OG Xbox struggled to run the USA and Japan, but the european Mario Tennis ran very smoothly.

    Yeah, I’m using the PAL versions. It’s still slow. To get better performance, should the CPU clock be a higher or a lower percentage?

    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.

    I was hoping Saturn emulation was fixed in the new version of Lakka without being mentioned, but just had a freeze on Panzer Dragoon Saga. I turned threaded video on.

    Nevermind, was going to say it was because I changed resolution to 2x, but changed it back to original and it froze again.

    I turned off threaded video and overclocked CPU and GPU and haven't had any freezes, but I haven't played for like hours and hours so I can't say 100% for sure that will make it work completely.

    Does anyone know if there's a way to tell Retroarch to restrict the mouse tracking (as a lightgun) to the viewport of the game?

    For example, arcade lightgun games (Revolution X, T2) display at their proper aspect ratio (4:3ish), but use the whole touchscreen (via mouse input) for the lightgun input. So the aiming is off because the corner of the touchscreen (at 16:9) corresponds with the boundaries where the 4:3 screen area is.

    Note: Other cores seem okay, at least when testing Mad Dog McCree with the Dolphin core.

    Edit: As much as I'm a stickler for proper aspect ratios, I think my only option is just to stretch the video for those games to fit the screen, so then it matches the mouse tracking. Sucks, but better than nothing!

    I have been trying to do this but can’t for the life of me figure how to make this work. Can you explain how you located the genesis core? I would like to see if i can possibly use the older N64 core in the new build. Ive used the sudo apt-get install commands, but how to find individual core folders in files? Is their a file path you can remember?

    I brought this same issue up a few times in this thread (unanswered) for the ScummVM core and its tap/mouse interface, so I echo your concerns.

    I know you copy it to /lakka/storage/cores, but pretty sure it does only work with this method if the core doesn't already exist. So Flycast from the new build will work with the old version, but when I tried to transplant the version of GPGX I compiled to the new one, I think it got confused because it already existed.

    Sorry I can't be of more help :(

    Ah man, that sucks to hear. But at least that kind of reassuring/interesting to know that if it's happening across multiple cores, then it's a Lakka OS/UI problem that should be fixable.

    Also explains why there's different behaviour again in Retroarch for Horizon, because it only works like a laptop touchpad and nothing like Lakka.

    The only kind of fix I found was to stretch the image to 16:9. I know it ruins the scaling but at least the touch will be aligned with the display.

    My only worry is that ScummVM doesn't have that functionality. At least not for all games. There is an aspect correction feature but it only works for 320x200 games I believe. For 640x480 games it won't work and that's a square aspect ratio. And even still I doubt an uncorrected 320x200 aspect ratio would stretch to the full width of the Switch's display. I'll have to experiment with this, though. I haven't tried it.

    EDIT: Nope. Actually the aspect ratio correction and fullscreen functions do absolutely nothing. So the core or Lakka must be forcing its display output automatically to a corrected aspect ratio. Or those features are hardcoded instead.

    Just in case if you knew, for resolutions to take effect, you need to restart (Similar to restarting retroarch) From 360p to 720p for example.

    Nps, I managed to locate the cores from the prepackaged l4t noobs version niether n64 core works. One just gets a black screen and the other failed to load core.

    I know Reicast on the older version does, I didn't test the new one because DC stuff crashed for me using Flycast.

    — Posts automatically merged - Please don't double post! —

    Damn then! I did message Natinusala on Twitter asking if there's something that can be done about mouse scaling or it's window, perhaps something might come of that. Even if it involves compiling something myself, I dunno.

    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.

    Try and reset the directory for bios and if you havent, the retroarch.cfg file. Can confirm dc games work just as well as before.

    I appreciate it but I am trying to get Naomi games to work not Dreamcast. Are you saying Naomi games work? Or just Dreamcast? There's a huge difference. But it would be the same core Reicast/Flycast.

    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.
