The SPU file type is associated with Spectrum 512, an image file format used by Spectrum 512, a program designed for the Atari ST series of computers. Spectrum 512 was notable for its ability to display up to 512 colors on screen simultaneously, a significant achievement for its time given the hardware limitations. The SPU file typically contains bitmap images created or manipulated within the Spectrum 512 program, capturing the detailed and vibrant graphics that were possible with this advanced color display technology. These files are primarily of interest to enthusiasts of vintage computing and digital art historians studying early computer graphics.
A CUR file is a cursor image or animation used for the Windows mouse pointer. It may be an arrow (for general use), a spinning hourglass (for waiting periods), or an I-bar (for text editing).
