# verify-iigs-input.sh - Headless typed-character acceptance gate for the
|
|
# IIgs port. Boots GS/OS under MAME, launches the KEYS example off
|
|
# joey.2mg, types the RetroNet definition-of-done string on the emulated
|
|
# keyboard, and reads the example's verification scanline (row 198)
|
|
# straight out of SHR memory. KEYS encodes every character it received
|
|
# from jlInputGetChar as raw nibble pixel pairs behind an A5A5 sentinel,
|
|
# so the row bytes must equal the typed ASCII exactly -- proving digits,
|
|
# '.', and ':' all arrive through the typed-character queue.
|
|
#
|
|
# Usage: scripts/verify-iigs-input.sh
|
|
# Requires: toolchains/env.sh sourced; build/iigs/bin/joey.2mg built
|
|
# with the current KEYS (make iigs-disk).
