Hi, the palette is a special MUI/MagicWB-compliant, OCS-compatible, MagicTV-compatible, 16 colour palette designed to avoid some AGA hardware bugs caused by certain shades, and generally remaps images better than any other 16 colour palette known (including the RiscOS, MacOS, Windows and Arne 16 colour palettes) locked with FullPalette. My good friend Rebel worked for years adjusting and calculating it to be this perfect, it is such a shame Commodore never thought of something like this, Workbench flies in 16 colours and it looks quite nice.
The window frames and gadgets are customised with VisualPrefs, and the textures are added with Birdie2000. The task bar program is called Workbench2000, and it's a pain in the butt to configure but it's simply the best one I have found that works on a non-RTG system. The fact that you can "minimise" any window on the Workbench makes it one of the most useful tools I have used, it's something you can't normally do. This is different to iconifying, where the whole program changes its state and removes itself from the screen, Workbench2000 is clever in that it knows that the Workbench desktop is just a backdrop window, so it sends "minimised" windows behind it temporarily, so they're out of sight, revealing the desktop, but can be brought back to the front by clicking the tab again. It's a lot quicker than iconifying and uniconifying programs, especially when all you want to do is quickly see or click on something on your desktop. I used a Hex Editor to change the "Start" button to a "Cammy" button, since it has to be another 5 character word. The only bad thing is it takes a little while to load up since it preloads all the images.
We picked up that arcade cabinet intending to turn it into a MAME machine, but once we got it home and inspected it we decided against it, the whole thing is rotten and would just need too much work to get into a decent state again. Instead we're just going to build a custom cocktail cabinet from scratch and stick an Amiga 1200 inside there with a wireless card, internal monitor as well as video-out ports, internal joysticks as well as external 9pin ports connected to joystick switchers so you can plug in a pad and sit back on the couch and use the TV rather than hunching over the cabinet and using its internal screen and joysticks. That way a mouse could also be plugged in so we can browse the web and download games from the couch.
The player I'm using is EaglePlayer, and it's just playing Mods, no MP3s on my Amiga sorry. I do have some WAVs that were converted from MP3s which sound great, and don't hog the CPU (but they do take up more space, which doesn't matter when I just store them on cheap SD cards).
