This bash script converts LHAs, .HDFs, or zipped directories to HDFs usable in lr-puae in RetroPie.
This requires Python, PiP, amitools, and lha.
sudo apt-get update
sudo apt-get install python-pip
sudo pip install amitools
sudo apt-get install -y lhasa
apt-get install zip unzip
Then download and install this package.
sudo chmod a+x amigatool*
sudo chown pi:pi amigatool*
Put the entire package (scripts, blankhdfs folder) in the directory with your Amiga roms.
./amigatool.sh filename
If the file is a .lha, it will be unpacked into a temporary directory, then rebuilt into an .hdf and placed in a new /hdf directory with the main .slave file renamed to game.slave. This will then run directly in lr-puae just like an .adf.
If the file is a .zip with the Amiga files loose in it, it will be unzipped, then rebuilt into an .hdf compatible with lr-puae and copied to the /hdf directory. If the file is a .zip with an .hdf in it already, the .hdf will be converted to be compatible, if necessary, and moved to the /hdf folder.
If the file is a .hdf, it will be converted if necessary, then moved to the /hdf folder.
Note that these are not bootable .hdf files, as they do not have Kickstarts in them. They presume that
you have properly set up WHDLoad.hdf and placed it in ~/RetroPie/BIOS
The files will be output as zipped .hdf files which can then be scraped. Note that unzipped .hdf files will not work with some scrapers.
./amigatool-batch.sh
This will go through every file in the folder in which it is run, and call the previous script on each one.
