Reproducible 0.2.6b SIGTRAP under macOS 15.2

Thu, 09 Jan 2025 09:45:56 UTC

I'm running pico-8 0.2.6b under macOS 15.2 (24C101)

I have only seen this with one cart from the BBS, but it seems reproducible. I don't know if the cart is doing anything unusual but it manages to crash the pico8 process entirely.

If I load #GORDY_AND_THE_MONSTER_MOON-0 (new today in splore), get through the story intro, move a few screens up and jump down the ladder; pico-8 repeatably crashes with:

Crashed Thread:        0  Dispatch queue: com.apple.main-thread

Exception Type:        EXC_BREAKPOINT (SIGTRAP)
Exception Codes:       0x0000000000000001, 0x0000000100778930

Santa's Present Panic

With presents shooting out at dizzying speed, can Santa keep it together?

Santa's Present Panic

by shadowphiar

[Click to Play]

A puzzle arcade game of quick reactions and keeping calm under pressure.

Presents in various shapes will descend from the chutes. You must move the belt left and right so that the holes in the belt match the falling shapes above.

Line up as many as possible, then press C to release the matching shapes and they will fall through the holes. Be careful not to move the belt until they're all through! If a shape hits the belt where it can't go through, it explodes into dust and the chutes will descend quickly!

The chutes will slowly descend and the only way to get them back up is to drop several shapes together. The more shapes you get the higher they'll go. If the chute reaches the bottom the machine will stop!

Keep the machine running as long as possible. Can you make enough presents to save Christmas?

Controls

Left and Right: move the belt
Down: pull shapes downwards without releasing them
🅾️: release shapes that match the belt.
Return: open the pause menu, where you can quit the game in progress, toggle music etc.

P8ZZNIC - A PICO-8 Interpretation of the Tile-Matching Classic, Puzznic

P8ZZNIC 1.02

by shadowphiar

[Click to Play]

A puzzle game to exercise your brain

Get ready to challenge your mind with P8ZZNIC, a PICO-8 tribute to the arcade puzzle classic, Puzznic. Your mission: clear 144 screens by matching tiles adorned with various symbols. Use your cursor to move blocks left or right — when two or more matching tiles meet, they vanish. Earn bonus time by orchestrating clever trick shots that clear four or more tiles at once. But beware — plan your moves carefully, or you might leave behind an unsolvable puzzle!

Each level in P8ZZNIC consists of four screens. After completing a level, you'll return to the level-select screen, and your progress is automatically saved.

Controls

o : select tile. While holding a tile, push left or right to move it.
Hold x : reset the current screen

Notes

Unlike the original arcade game, the clock in P8ZZNIC counts up instead of down. Without the pressure of a time limit, you can focus on solving puzzles without worrying about losing progress. This makes for a more laid-back gaming experience—perfect for thoughtful puzzle-solving. However, for those seeking an extra challenge, you can replay levels to improve your clock time and compete with others by posting your best records in the comments. Pro tip: set up chain reactions for massive bonuses that reduce your clock time!
