Comet v3.2

Comet 3.2

More performance work, short one this time.

Faster

• The grid now fills noticeably quicker, especially on repeat visits. Thumbnails are cached on the SD card after they're first built.
• Building thumbnails now adapts to how fast a given SD card actually is, instead of assuming a fixed pace

Comet v3.1

Comet v3.1

Performance and a small UX cleanup, no new features this time.

Faster

• Deleting a 3DS screenshot is significantly faster on a large library.
• Faster startup
• Merging no longer shows a confirmation popup on success

Comet v3.0: Nexus 3DS Support and QoL changes

Comet 3.0

• Full Nexus3DS compatibility, a new way to preserve both screens at once, and a long list of navigation and polish fixes.
  Nexus3DS support
• Reads Nexus3DS screenshot filenames, which embed the running game's title ID between the timestamp and the file suffix
• Supports Nexus3DS's optional "save screenshots in date folders" layout, alongside the regular flat one
• Both work on the same SD card as plain Luma screenshots, with no need to pick one or the other

Also new

• Merge Top/Bottom Screens, from any 3DS screenshot's More screen. Combines both screens into one image and adds it to your
  gallery with its own badge. No stereo 3D
• Every screenshot's More screen now shows its full file path, since screenshots can come from several different places now
• Move between screenshots directly from the More screen with Left/Right, no need to back out to the grid first

Quality of life

• New badges distinguishing nds-bootstrap tar screenshots, ones already extracted to SD, and merged screenshots from each other
• Redrawn badges throughout, fixing some stray white pixels visible on 3DS XL screens
• Copying to the Album, extracting from the tar, and merging now all keep you where you were instead of dropping back to the grid
• Deleting a screenshot is now more thorough about removing its companion files, including inside Nexus3DS's date folders

Fixed

• Sound effects didn't play for some touch-only interactions (opening a screenshot, switching DS tabs, tapping a filter), even
  though the action itself worked correctly
• Touch-holding "Show Bottom" played its sound but never actually showed the bottom screen. Physically holding the button still
  works throughout

Comet v2.1: Experimental Nexus3DS Support

⚠️ Experimental pre-release — not confirmed working on real Nexus3DS
hardware yet. If you use Nexus3DS, trying this and reporting back
would help a lot.

• Correctly reads Nexus3DS's screenshot filenames (title ID included)
• Supports Nexus3DS's "save in date folders" layout
• Reads Nexus3DS's own combined top/bottom screenshots (_cmb.bmp)
• New: Merge Top/Bottom Screens, from any 3DS screenshot's More screen —
  combines both screens into one image, no stereo 3D

Comet v2.0

Comet 2.0

The headline addition: full DS screenshot support, alongside a
long list of polish across the whole app.

DS Mode

• Press L+R from the main grid to switch to DS screenshots. The
  toggle only appears once Comet actually detects one, so it stays
  out of the way if you don't use it
• Reads nds-bootstrap's screenshots.tar directly. No manual
  extraction needed first
• Two tabs: what's still in the tar, and what's already extracted to
  SD. Browse, filter, copy, and delete from either
• Extract individually or all at once, with a safe compacting delete
  that keeps nds-bootstrap's own screenshot count correct
• Widescreen support for DS games with a 16:10 patch, remembered
  across restarts

Also new

• Installable .cia build, with its own HOME Menu icon and banner,
  alongside the existing .3dsx

Quality of life

• Sharper icon and text rendering throughout. Buttons, badges, and
  menus all read more clearly than before
• Sound effects now only play when a button press actually does
  something, instead of on every press regardless of effect
• General visual and usability polish across both 3DS and DS modes
• Bons: Hidden L+R duplicate shortcut on the More screen, for testing

Fixed

• Opening the More screen right after moving the cursor could act on
  a different screenshot than the one shown on the top screen
• Grid navigation could get stuck when the last row had fewer items
  than a full row. Some columns simply couldn't reach it

First public release

Comet 1.0

The first public release — an all-in-one 3DS screenshot manager for Luma3DS/Rosalina captures.

Features:

• Grid browsing with D-Pad and touch, live stereo 3D preview
• Copy to the 3DS Camera album — .MPO for 3D pairs, .JPG for 2D shots,
  individually or in batch
• Delete, individually or in batch, always with confirmation
• Filter by All / 3D Only / 2D Only, or drill into Year → Month → Day
• Peek at Luma's bottom-screen capture alongside any screenshot
• Sound effects and a visual style modeled on the Switch's Album app

Installing:

• Comet.cia — installs to your HOME Menu (needs a CFW with patched signature checks, e.g. Luma3DS, plus an installer like FBI)
• Comet.3dsx — copy to sdmc:/3ds/Comet/Comet.3dsx, launch from the Homebrew Launcher
