Clicking Play Not Working on Some Games

[zahroc]

Trying to play some imported ROMs. Launchbox and RetroArch imported them just fine.

When I double-click or click play, I get the cursor spin and then nothing. If I right click on the game, open retroarch and manually select the core (which is configured correctly in Launchbox) and select the content, it works fine.

LaunchBox v13.24

RetroArch v1.22.2 / Core Mupen64Plus-Next (2.8-Vulkan 680e033)

Windows 11 Professional 25H2 Build 26200.7462

Suggestions?

Other platforms work ok on newly imported ROMs.

For troubleshooting purposes, double/triple check your LaunchBox settings for the platform and maybe share some screenshots.

In LB, edit the emulator and share a screenshot of the main Details section and also the Associated Platforms section (where your N64 platform is visible). Verify that Default Emulator is checked.  Verify that Extract ROMs is un-checked.  You already verified the correct core is selected.

Edit one of the N64 games and show the Launching section (verify it's pointing to an n64, bin, or whatever format you ROMs are in).  Also show the Emulation section (verifying that RA is the set emulator and that there are no overrides set).

If your ROMs are zipped (for some reason), confirm there's just 1 file inside it. (In this case, Extract ROMs [mentioned above] would be checked). If there's more than one file inside the zip, the wrong one may be being send to RA.

If your ROMs are zipped, (for testing purposes) try extracting one of them, point that game to the extracted file (making sure extract ROMs in unchecked in the emulator) and try launching it from LB that way.

Unzipping fixed the issue. Odd since some zipped worked and other did not. Thank you for the suggestion.

If the single ROM file inside the zip is named differently than the zip, it may cause the issue.  (but I'm not for sure on that).  In the end, those ROMs are small to begin with, so having them zipped has no substantial gains.

Glad you got it working.
