NetHack 3D 1.4.1: Windows, macOS, Linux, Android

New Tileset: PixelHack

• Added PixelHack, a newly-created tileset by "samuel", and made it the default for new NetHack 5.0 players. Thanks to samuel for his 17 years of dedication creating this beautiful new tileset! See his blog here: https://pixelhack.blogspot.com/
• Added dedicated background-removal handling for PixelHack, combining tile-based and solid-color chroma keying so its sprites render cleanly without manual configuration. These settings are locked in the Tileset Manager for this tileset since they're tuned specifically for it.

Improvements

• When the "A saved game named <name> already exists. Do you want to overwrite it?" prompt fires, it now offers a third button, Load Existing Save, that resumes the detected save and ignores the new-character inputs.

Fixes

• Autosaves fixed for all runtimes (NetHack 3.6/3.7/5.0, SlashEm) — a recent stats-tracking change had inadvertently broken autosave/checkpoint persistence across the board. Checkpoint and level shards now consistently use the dedicated save-file storage they originally relied on, restoring reliable game resume.
• Fixed default tilesets sometimes failing to resolve correctly for new users, so first-time players now reliably get the intended default tileset for their chosen NetHack version instead of a mismatched fallback.
• Fixed a bug where a player's tileset choice could be silently overwritten when playing NetHack 5.0, especially after switching between runtime variants.

Known Issues

• Shop selling might not work while in FPS mode. Reportedly works in overhead mode. I'll try to fix this next time!
