I look at #Commodore64 demo "Hexed" by Element54. Are there impossible horizontal splits? Is there screen scaling? Large twisty rotating sprites?

I look at #Commodore64 demo "Next Round" by Performers. The many parallax layers, smooth pinball parallax, and 3D filled vectors without bitmap mode.

I look at #Amiga "Mr Nutz: Hoppin' Mad" published in 1994. Mostly looking at the lovely extra parallax of a later level, the 3D rotating section, and scaled sprite boss level.

I look at #Commodore64 "Glider Rider" published in 1986. This isometric game uses hires bitmap and dynamic hardware sprite animations with masking. I extract the graphical data, and discover the map format in memory.

I look at recently released #Commodore64 Wizball music source code, get it assembling using Acme assembler, and find some unreleased new music that was not in the original Wizball.

I look at #Amiga "Zippy Race!" a nice work in progress arcade perfect conversion by Dimitris Giannakis - MVG . Using a nice triple buffer extra space scroll, blitter objects, and hardware sprites.

When the #Commodore64 Wizball music source code was recently released, of course it inspired me to do a video...

I look at #Amiga "Mr Nutz: Hoppin' Mad" published in 1994. Mostly looking at the lovely parallax and how the game uses hardware sprites for the player and score display.

I look at #Commodore64 "Galencia" published in 2017 by Protovision. Lots of polish in this game, lovely sprite multiplexor, sprite colour splits, and parallax stars. It plays really well.
