Other Fixes and Updates

• Browse dialogs now remember the last visited location.

• When loading the Games list, .cfg files containing the word “Palette” are ignored to prevent palette configuration files from being interpreted as game configuration files.
• Added a button to open the .ini file directly.
  • Useful on macOS, where the .ini may be created in a different location than the application.
• Added an Analyze option that checks game JSON entries for:
  • Missing fields
  • Invalid file references in jzintv_extra
    (Analyze currently evaluates games only; folders are not included.)

#Change Log (build-2512162037)
This release has the following minor updates.

• Handle "other" JSON values: If JSON file contains "additional" settings, like "save_highscores", SGM will show and preserve those.
• Default JSON Description to blank: The Sprint does not handle a description set as empty string, so SGM now sets descriptions to single blank space when no description provided.
• Show empty input for year when set to 0: Year input field will be empty if year value is 0. This improves usability as don't need to clear the field to enter a year.
• Paste only text to description field: when pasting text to description fields, no longer shows source formatting, just pastes plain text.
• Prepped changes for a Mac: Changed path logic and icon logic to ready for building Mac .app binary.

Sprint Game Manager (SGM)

Desktop GUI for managing Intellivision Sprint Console games (ROM, config, metadata, and images) for sideloading.

Using the app (end users)

1) Pick your games folder

• Use the folder picker to choose the root folder that contains your game files.
• The game list populates from the detected basenames.

2) Select a game

• Click a game to edit its assets.
• The top-left warning counter reflects missing/invalid assets (including image resolution mismatches).

Analyze the games folder

• Use the Analyze area to scan the currently selected games folder and compute warnings per game.
• Use the warning filters to show only specific issues (missing ROM/config/metadata/images, resolution mismatches, etc.).
• Enable Only games with warnings to quickly narrow the game list.
• Use the select all / clear all filter buttons to toggle filters faster.
• If you add/rename files, re-run Analyze (or Refresh) to update results.

3) Add / rename content

• Drag & drop accepted files into the app (or use the Add actions) to copy them into the selected game.
• Use Change File Name to rename the game (updates associated files).

4) Edit metadata

• Use the metadata editor panel to create/edit <basename>.json and save changes.

5) Manage images

Each image card supports:

• Browse: pick an image file.
• Paste: paste an image from the clipboard.
• Drag & drop: drop an image file onto the card.
• Resize (when shown): fixes wrong-resolution PNGs.

6) Overlays (1–3)

• Build: generate an overlay from a template + bottom image.
• Blank: sets the slot to the packaged empty overlay image.
• Keep Ratio (overlay cards only): when checked, Browse/Paste keeps the source aspect ratio and centers it on a transparent canvas (no stretching).
• Reorder overlays: if at least two overlay files exist, drag one overlay card onto another to swap/move their underlying files.

7) Snapshots (1–3)

• If you have multiple snap images, drag one snap card onto another to swap/move _snap1/_snap2/_snap3.

8) QR code
