# PSP build rules: JoeyLib programs as PSP homebrew, through the hosted core
# and the same SDL3 backend the sdl3 port uses (src/hosted,
# src/hosted/sdl3), cross-compiled with pspdev's psp-gcc against SDL3's PSP
# port (the installer's sdl3Psp component). The rules are make/hosted.mk's;
# this file says what is the PSP's. A project reaches it through
# make/project.mk.
#
# A program is a folder of its own, bin/NAME/: EBOOT.PBP, titled ID_TITLE
# (or NAME) in the PSP's menu with its icon (ID_ICON, ICON0 in the EBOOT),
# and its DATA/ beside it. The folder goes into
# PSP/GAME/ on the memory stick as it is: the program's folder is its
# current directory, as on every port, so DATA/, SAVES/ and joeylog.txt are
# there. The ELF the EBOOT.PBP is packed from (make/support/psp/packEboot.sh)
# stays in build/psp/elf, for psp-addr2line.
