Edit: I'm no longer looking for help with this. The issue seems to be with the app itself and I have submitted a bug report for the app on github.
Before you tell me I should try another n64 emulator, I have been using other emulators but I have a game that isn't working and I'm trying to run it in other emulators.
Anyways, if I try to run simple64 through the terminal, I get the error message:
Failed to load module "xapp-gtk3-module"
I tried to look into this and it seems that I'm supposed to install "xapp" but I'm getting the error message:
The following packages have unmet dependencies: xapp : Depends: libxapp1 (= 2.2.8-1) but 2.8.2+virginia is to be installed E: Unable to correct problems, you have held broken packages.
I tried to fix it with sudo apt --fix-broken install xapp
but it's just giving me the same error message. Is there anything else I can try before I try another emulator?
The APT error is most likely a result of using PPAs - some PPA you use (probably the one with simple64) provides libxapp1 2.8, but doesn't provide happy at all, so you end up falling back to the much older version from your distro's repositories. But xapp needs an exact version of libxapp1, so you get this error.
That said, if the simple64 PPA doesn't provide the xapp package, then it perhaps isn't required and the module should be provided by libxapp1 (and the problem is something different). Or maybe it comes from a completely different PPA - I believe
apt policy libxapp1
should tell you where it's coming from.Simple64 isn't a PPA, it's downloaded from flathub and the github page only links to flathub. If you are seeing a PPA, it's probably not real. Also, I'm not sure what to do with the information but that command gives me:
libxapp1: Installed: 2.8.2+virginia Candidate: 2.8.2+virginia Version table: *** 2.8.2+virginia 500 500 http://mirror.team-cymru.com/mint-packages virginia/backport amd64 Packages 100 /var/lib/dpkg/status 2.2.8-1 500 500 http://archive.ubuntu.com/ubuntu jammy/universe amd64 Packages
If it's a Flatpak, then installing anything with APT shouldn't help you at all - it is possible to build a Flatpak that accesses host libraries, but it would defeat the point of using Flatpak in the first place. So your xapp issues are moot anyway.
As to the meaning of the output of apt policy: it says that the most up to date libxapp1 is from Linux Mint repos, and that there's also an older version in Ubuntu repos. That means that Linux Mint doesn't provide a xapp package at all, and the only one you could install is the old one from Ubuntu (which conflicts with the newer libxapp1 from LM)
Ok but is there anything I can do to get simple64's flatpak working or should I just move onto trying another N64 emulator?
Not really - report your issue on their issue tracker if you can and feel like spending your time on it, then move on (and maybe check back in some time). Flatpak are meant to fix dependency issues, there's not much you can do if they got it wrong for whatever reason.
Ok, I'm actually in the process of filling out the bug report right now.
