Dragons Lair on the Amiga

Loads of them, using a long track MFM system wasn't anything special.

Psygnosis, Rob Northen, Gremlin, Sensible Software, Vectordean, Rainbow Arts, Arc Developments, most publishers used it at some point.

what about going from 880k to 1.04mb on a standard Amiga floppy?

This is what I thought, it was a pretty normal thing. Not sure why the video makes a big deal of it, perhaps he was the first to do it?

Actually you can push up to + 32 bytes!

He wasn't the first, but a combination of factors made it a no small effort to do.

Pretty sure Turrican 2 and the Psygnosis MFM format are larger

I wonder if instead of the dual playfield framegrabbing a triple buffering vector approach for storing pictures like in another World, State of the Art or Nine fingers would have worked with a laser game

Related to Dragons Lair, you guys might enjoy this video delving into the history behind the game as well as the attempts at creating follow ups

Its a really fascinating story that tends to get overshadowed by Don "Did I tell you I am Dun Bluth" Bluth

So if I understood it correctly there was a lot of trickery going on with using the copper and blitter to control the program actions.
Makes me wonder if anyone ever made a Turing-complete and programmable cpu using those. That would be a nice level of obfuscation...

No, the main game code is heavily encrypted, and instead of using a cpu approach to decrypting, he used the blitter to decrypt...which was controlled by a copper list to pass the parameters needed to the blitter to decrypt.

I did a "history of" video a few years back

By the way, anyway that craps all over the Amiga version clearly don't know what they're talking about. It was amazing seeing this running on a computer back in 1989 even with all the floppy disk swaps.

Oh, and DL supported one type of A1000 HD too IIRC?

Yup:

Installation is possible to a HD or Bernoulli connected to a Comspec SCSI controller only

^ because, as indicated in the manual, no other company wanted to provide technical specifications/details of their hardware to Readysoft (needed for copy protection installation).
But thanks to the 2nd opus (Escape from Singe's castle) HD installation of the first Dragon's Lair was possible on any HD/Controller .

It was a whole host of things added together that was the reason for its long delay.

Yep. But forgot about the video. Oups...

I skimmed through your video -- quite comprehensive. Some of the best ports that I have seen are first the DVD (home video), then the WII, and then finally BD.
