# retroDE_ps2 — copy the Ch357 persistent-Z (256x210, GS_SH3_LPDDR_FB_Z) board-side files to the DE25.
#
# This is the file set for the ZSCHED profile (sh3_zsched_epochs.txt, fbpxw 256 fbh 210) — the one built by the
# GS_SH3_LPDDR_FB_Z RBF. (NOT sh3_sched=384 or sh3_s640=640; those are other profiles.) Copies to the home dir so the
# host runs from ~ and the epoch descriptor finds the tex/list files by their relative names.
