Aspect Ratio Control & Play Time Tracking

This release introduces two new features and a key bug fix for the external display experience.

New Features

1. Preserve DS Aspect Ratio on External Display

• New setting to maintain the original DS aspect ratio when using an external screen.
• Prevents distortion or stretching on TVs or monitors.
• Available in the Quick Settings dialog during gameplay.
• The external screen renderer now adjusts its viewport dynamically based on this option.

2. ROM Play Time Tracking

• melonDS now tracks total play time per ROM.
• Play time is displayed directly in the ROM list, beneath the ROM title.
• Changes include updates to:
  • Rom model and RomDto for totalPlayTime
  • RomsRepository logic to support play time aggregation

Bug Fix

• Fixed screen filter not applying on external screen when swapping the top and bottom screens.

Nightly Build Available

• A new nightly build is included to allow side-by-side installation with the official version by rafaelvcaetano.
• This nightly is functionally identical to the main version, no extra changes, only a different package ID.
• Useful for testing or using both builds independently on the same device.

Thanks to everyone continuing to test and improve external display support!
