Install uaegfx

install_uaegfx.sh writes the card and a monitor named uaegfx. ScreenMode is the click that remains.

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.

Picasso96 is how the A1200 gets a screen larger than the chipset can draw. Its installer spends most of its windows confirming a copy, then asks which board to install. On WinUAE the board is uaegfx. install_uaegfx.sh writes that card, the RTG libraries, and a monitor named uaegfx. It does not install the drivers for real Picasso cards, and it does not install the MiSTer framebuffer. Do not run install_picasso96.sh here. That script deletes uaegfx.

Automated
The board
Leave the board set to uaegfx and press Proceed through the copies.
./install_uaegfx.sh Workbench.hdf Picasso96.lha, or --picasso Picasso96.lha on setup_winuae.sh. The card lands in Libs/Picasso96/uaegfx.card. The monitor is Devs/Monitors/uaegfx.
Skipped
Picasso96Mode
Skip the mode editor. It is for a real card.
Skipped. The script does not write that preference.
Still a button
ScreenMode
Open ScreenMode, pick a uaegfx resolution, set the colours, and save.
Saving the mode is still that window. The pipe does not move the slider, but AmiPilot can: run_interactive_winuae_acceptance.sh picks the 640×480 uaegfx row by reading Width and Height back from the window, drags Colors to the top, and saves. Under Scalos it has to be Save and a clean restart; Use raises a requester that never proceeds.

The manual steps are Chapter 5 of the Green Amiga Alien guide. The commands are in amiga-utils.
