All XBN externs

A game loads exactly one GAME.XBN. This folder holds every extern in the collection except transcript, built into a single binary, so you can copy one file to your card and use any of their functions without an assembler.

Transcript is NOT in this binary - it is the one module the collection leaves out. The loader arms the output hook tap for any binary whose header names one, whether or not the module is recording, so a binary carrying that hook costs every game that loads it on every printed character. With no hooked module here, this binary carries a plain format 2 header, which any interpreter version loads; playername's SVC_GETLINE and ticker's SVC_PAIR/SVC_FITWORD need API 3, each module checking the version itself, not the loader. Ship ../transcript/GAME.XBN on its own, or fold it into an EXTERNS.BAT subset, only in a game that means to record.

To use it: copy this folder's GAME.XBN next to your GAME.DDB, then add the DSF lines from whichever module's README you want. Each module documents its own EXTERN condact fn codes, for example EXTERN n 30 to arm ticker. Function codes and flags are disjoint across the collection, so modules never collide.

Modules stay inert until the game invokes them - an arming call for the modules that use one, or simply never being EXTERNed for the ones that don't. A module the game never invokes never reads or writes its flags, so its flag block stays yours.

If you would rather ship a smaller binary with only the modules you use, run EXTERNS.BAT from the kit root - see the collection README.

CALL targets are slots in a fixed jump table at $C00E, not routine addresses: slot n is at $C00E + 3n. Slots whose module is not in the build return harmlessly.
