Viewer (Java version) showing a ZX Spectrum loading screen for the M.A.S.K game!
This application allows you to view and play some obscure file formats. It was originally made to view Cybiko video files (hence the name) but has since been expanded on. I also had various Amiga renders and animations that I could not easily view and a bunch of other decoders so included them as well!
The following file formats are supported, compatibility may not be 100% due to the lack of test files I had available:
Amiga - IFF bitmaps and animations including HAM6 and HAM8 modes and Extra Half-Bright (EHB).
Cybiko - Images (.pic, .cvi) and Video (.cvc) formats.
ZX Spectrum - Screen dumps (.scr). Java version only!
Autodesk FLI / FLC (256 colour) animations.
AVI - Video only RAW / DIB (Uncompressed) and MSVC1.
Quite Okay Image (QOI) format images.

Despite the different version numbers, the Windows and Java versions are virtually identical. The number really just indicates bugs found and fixed...
This version requires .NET 10.0 (64bit), you will get a prompt telling you how to get it if you do not have it installed.
