`Incorrect ROM file - No valid ROMs were provided` (Verified Checksums)

[ThisNekoGuy]

• [x] I have checked the known issues and searched Github to ensure this issue has not already been reported.
• [x] This is not a feature request, I know those belong on Discord/Github Discussions.

Description of the bug:

Can you reproduce? If so please list the steps:

• [x] Yes, here are the steps to reproduce the bug:

1. In my case, I compiled from source then had the following in a folder: 2s2h.sh 2s2h.elf gamecontrollerdb.txt 2s2hIcon.png
2. cd to the folder containing these items via terminal (in my case, extracted from a zip archive)
3. Run ./2s2h.sh
4. Encounter the strange behavior (on a first attempt, it may look fine but you'll notice there's only a mods folder; subsequent attempts show the described behavior below)

Expected behavior:

When running the Linux launch script, the Zenity pop-up claims that no valid rom was found and yet also attempts to generate an OTR in a seperate window regardless before eventually closing itself. Additionally, only the mods folder ever seems to get created and I never find the temp directory that's supposed to be made in /tmp despite having user permissions to do so.

Hi, are you still encountering this problem?

I think in this case what you are missing is the compiled ZAPD.out binary and the assets folder that contains all the xml files for extraction. Without this, the 2s2h.sh script won't be able to generate an mm.o2r properly. The script is provided as-is and assumes that it is running from the appimage. You can refer to our CMake and CPack steps to see how we are bundling the final appimage.
