I look at #Amiga "Lionheart" published in 1993. Using two emulator-debuggers to show double buffered screens, with swapping pristine buffer, more sprite copper tricks, and parallax scrolling.

I look at #Commodore64 "Dragon Breed" published in 1990 by Activision. The sampled intro with zoom animation, flickering multiplexor, and use a tool to emulate a Ye Olde Style CRT TV.

Yes it's an 8 megabyte flash #Commodore64 cartridge.
I thought I would add a test menu, like the original arcade version, for #MegaWang After Burner... This will make it easier to test my new Audio3 PCBs.
I look at #Amiga "Turrican" published in 1990 by Rainbow Arts. It uses a double buffer plus pristine buffer for the scroll, with minimal edge updates, and also look at some of the early boss sections.

I look at a few #Commodore64 games and show how they unlocked super secret hidden colours... Not really, it's quickly alternating complementary colours with CRT display effects.

I look at #Amiga game "Leander", published in 1991 by Psygnosis. Interesting use of hardware sprites for parallax mountains, and player with pixel accurate collision to the game objects. https://youtu.be/gQYSRjGkhBg

I look at #Commodore64 "Mayhem in Monsterland" published in 1993 by Apex. I look at the HSP/VSP/DMA delay scroll, FLD scroll, a pixel scroll without hardware, and hidden/disabled sprites during the game.
