# retroDE_ps2 — copy the Ch360 shared-texture persistent-Z NATIVE-640x480 board files to the DE25.
#
# This is the C12 file set (sh3_zs640c12_epochs.txt, fbpxw 640 fbh 480): twelve authentic SH3 draws in FOUR ordered,
# shared-texture epochs at native screen coordinates. The C12 bootlet words are byte-identical to the loaded C6 RBF's
# bootlet words, so no re-fit is needed. Copies go to the home dir so the host can resolve relative texture/list paths.
#
#   ./tools/scp_zs640c12_to_board.sh                 # default terasic@192.168.50.161:~

#
# STEP 0 — CONFIRM THE C6-SIGNOFF CORE IS LIVE. This script copies the 7 host/data files ONLY, NOT the RBF.
#   C12 reuses its exact bootlet memory words. The host run must report four epochs, one fill, three reuses, and zero drops.
