An overview of programming keyboards and joysticks on the ZX Spectrum Next. A video looking at how to use joysticks and keyboards on the Spectrum Next, using C and z88dk.

To get a sprite on the screen we need to choose one of the hardware sprites and set its attributes. Things like its x,y position, which sprite pattern to use and so on.

Load sprites into the Next is pretty straight forward once you have the images in the required format. Edit sprites and make a sprite sheet It’s best to work out a workflow for creating sprites and editing them, the tutorials always show ready-made pixel data included as a C header file.

Bigger sprites 16x16 pixel sprites are pretty good, and you should probably make most of your games with them. The screen is only 256x192 pixels in size so a 16x16 pixel sprite looks quite large.

Bank switching and memory paging The Spectrum Next comes with 1 or 2 megabytes of RAM, but being an 8 bit CPU the most it can address at any one time is 64K.
