!C to CG4 Conversion: FAQ

What are !C files?

!C is a Hobetta image file extension associated with ZX Spectrum computers, which were one of the first types of home computers, released in the 1980s by Sinclair Research Ltd. They supported an 8-bit color rendering, hence the name Spectrum, as opposed to their predecessor models, the ZX81, which could only render black-and-white images.
