How they were rebuilt

Every game started from an original disk image, not from memory or a remake. The rules came out of the code that shipped.

]LIST

Telengard and TPro BBS were read from their Applesoft BASIC listings and ported routine by routine, keeping the original formulas and quirks. The Proving Grounds was rebuilt from the files on its three original disks.

*300L

Sabotage is machine code. It was disassembled with 6502bench SourceGen, and the physics, constants and timing were carried over from the annotated listing.

]SAVE

What the originals kept on floppy now lives in browser storage or SQLite, so characters, boards and ladders survive between visits.
