# verify-atarist-tilebank.sh - Tile-bank gate for the Atari ST: proves that
|
|
# assetbake's atarist encoder (interleaved planes, 4 plane bytes per row)
|
|
# writes exactly the layout the ST's native tile paste (src/atarist/stTile.h)
|
|
# reads, and that the ST build refuses a bank baked for any other target.
|
|
#
|
|
# Runs TILEBANK.PRG (examples/tilebank) under Hatari from a scratch GEMDOS
|
|
# drive holding it and the DATA/tilebank make/atarist.mk staged from the host
|
|
# gate's fixture. The program loads its own bake through
|
|
# jlTileBankLoadToSurface and through jlTileBankLoad + jlTilePaste, checks
|
|
# every pixel of both against the PNG, hashes both, and tries every other
|
|
# target's bake; its TILEBANK log line must say PASS with both hashes equal
|
|
# to the host gate's (scripts/check-tilebank.sh, run here for the value) and
|
|
# every other target refused. Hatari is stopped as soon as the line appears.
|
|
#
|
|
# Usage: scripts/verify-atarist-tilebank.sh
|
|
# Env: TILEBANK_DATA_DIR stage this DATA/tilebank instead (negative controls)
|
|
# Requires: hatari, EmuTOS, a host cc; build/atarist/bin/TILEBANK.PRG and its
|
|
# DATA/tilebank (make atarist).
