# verify-amiga-tilebank.sh - Tile-bank gate for the Amiga: proves that
|
|
# assetbake's amiga encoder (plane-major: 8 rows of plane 0, then plane 1, ...)
|
|
# writes exactly the layout the Amiga's native tile paste
|
|
# (src/m68k/planarTile.h via src/amiga/amigaTile.h) reads, and that the Amiga
|
|
# build refuses a bank baked for any other target.
|
|
#
|
|
# Boots an A500 (real Kickstart) in FS-UAE under Xvfb from a scratch directory
|
|
# hard drive whose startup-sequence runs TileBank (examples/tilebank), with
|
|
# the DATA/tilebank make/amiga.mk staged from the host gate's fixture beside
|
|
# it. 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 line in
|
|
# joeylog.txt 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. FS-UAE is stopped as soon as the line appears.
|
|
#
|
|
# Usage: scripts/verify-amiga-tilebank.sh
|
|
# Env: TILEBANK_DATA_DIR stage this DATA/tilebank instead (negative controls)
|
|
# Requires: fs-uae, the Kickstart, Xvfb, a host cc; build/amiga/bin/TileBank
|
|
# and its DATA/tilebank (make amiga).
