lha and Installer

install_c_tools.sh writes both files. The Shell stays closed.

Why any of this

The Amiga 1200 was the last great Amiga Commodore made, and the desktop people built on it is the one worth having back: Kickstart 3.1, AGA, a hard disk, a graphics card for a screen bigger than the chipset could draw, MUI for modern windows, color icons, and WHDLoad so every game lives on the disk instead of in a box of floppies. An emulator or a MiSTer puts that machine back on your desk. Getting to that finished desktop is the work.

You cannot download it ready-made. Workbench and Kickstart still belong to someone, so the disks and the ROM have to be yours, and Commodore’s own installer has to copy them. Everything after that is a recipe of Proceed buttons, the Green Amiga Alien guide, which people have followed by hand for twenty years. These notes turn that recipe into scripts, so someone new to Amiga emulation gets the upgraded A1200 in an afternoon, from disks they own.

The end of the road is a build nobody babysits. AmiPilot can sit inside the running Amiga, click what is left of the installers, and take a picture of the screen, so an AI agent can check that the desktop came up, that the icons are in color, that a game launches, and fix the script when they are not. Every page here is one step toward that.

Two small files in C: are what every later installer depends on. Chapter 4 opens a Shell, runs lha.run into RAM:, and copies the 68020 build to C:lha. Installer is the same kind of copy. Do it from the host, after Workbench is on the volume, or pass both files to setup_winuae.sh before the installer runs.

Automated
The copy
Type the two Shell lines that unpack lha.run and copy the 68020 build to C:.
./install_c_tools.sh Workbench.hdf --lha lha_68020 --installer Installer. Or add --lha and --installer to setup_winuae.sh.
Automated
If you only have lha.run
lha.run is an Amiga program, so the host cannot execute it.
./install_c_tools.sh Workbench.hdf --lha-run lha.run --installer-lha Installer-43_3.lha plants the self-extractor and a one-time block in S:User-Startup. The next boot finishes the copy.

The manual steps are Chapter 4 of the Green Amiga Alien guide. The commands are in amiga-utils.
