Additional App Viewer Support in the Pause Menu

📋 Summary

Expand Pause Menu support for Additional Apps so users can launch external viewers for files like images, CBZs, walkthroughs, maps, and strategy guides while in game.

❗ Problem

The Pause Menu currently has limited support for Additional Apps:

• PDF based items can be displayed, but other useful formats are harder to use

• If an Additional App relies on an external viewer or emulator, the Pause Menu may show the item but fail to pass the needed commands or parameters

• This makes it difficult to use image viewers or comic readers for maps, cheatsheets, manuals, and guides

As a result, users can set these workflows up in LaunchBox, but not reliably access them from the Pause Menu in Big Box.

💡 Proposal

Improve how the Pause Menu handles Additional Apps:

• When building the Pause Menu, check the relevant file extension to decide whether the item should appear

• If the Additional App uses an emulator or external viewer, do not exclude it for that reason alone

• Instead, look at the target content path and launch it with the correct app and parameters

• Support common use cases such as:

  • images for maps and cheatsheets

  • CBZ files for manuals or guides

  • third party viewers such as ImageGlass or comic readers

📦 Benefits

• Makes the Pause Menu much more useful for reference material

• Allows users to check maps, walkthroughs, and manuals without leaving the game flow

• Expands Additional App support beyond PDFs

• Better matches real world Big Box cabinet and couch gaming use cases

💡 Notes

• Ideal flow is: pause game, open guide or map, close viewer, return to Pause Menu, then return to the game

• Existing PDF behavior should remain unchanged

• This would improve compatibility with third party viewers already supported in normal LaunchBox workflows
