chddeck_osx.sh

#!/usr/local/bin/bash

# chddeck_osx.sh for Macintosh OSX 2022
# original script from https://www.emudeck.com/ EmuDeck installation.
# https://github.com/dragoonDorise/EmuDeck/blob/main/tools/chdconv/chddeck.sh
# modified to run on a local copy of ROM files to compress them before installing on SteamDeck
#
#    N O T E S:
#
# install chdman from brew! You need this for the script to do anything...
# $ brew install rom-tools

# INSTALL BASH 5 from brew! You need this since the bash on OSX is old and no mapfiles...
# $ brew install bash

# Modify the romsPath below to be the roms dir that you have locally...
# I use this rsync command to push file to the SteamDeck:
# $ rsync -ave ssh --exclude '.DS_Store' /Users/myuser/roms deck@192.168.CHANGE.ME:/run/media/mmcblk0p1/Emulation/

# that will push over all the local files you have in the 'roms' dir on your mac to the deck. Ensure that you copy
# the names of the folders on the SteamDeck exactly as they are in the /run/media/mmcblk0p1/Emulation/roms folder.

# Running -
# ensure you run as $ /usr/local/bin/bash ./chddeck_osx.sh so that you get the bash 5 installed from brew.
# but the first line of this file should do that for you as well.
