Spectrum 512 Enhanced *.SPU Spectrum 512 images with a 15-bit RGB palette. Created by Sascha Springer: http://blog.anides.de/ These are identical to Spectrum 512 uncompressed images with two exceptions. The very first long of the image data will be the file id: '5BIT' Spectrum 512 can't display the first scan line anyway, so the id should cause no issues. The upper 3 bits of a palette word are used to provide a 5th bit of RGB. Thus: red: xx0x1432xxxxxxxx green x0xxxxxx1432xxxx blue: 0xxxxxxxxxxx1432 These look like normal Spectrum 512 images by old viewers when the upper 3 bits are not used.
