Hi,
I've read this in the PSX Dumping Guide:

Unfortunately, no disc emulation or burning software currently supports SBI, neither do image formats. Our new image format with SBI support is in early development stage.

Are there any news about this image format ? any ETA ?

Thank you very much !

nope, never happened.
i think this was there when i came to this site and it never went anywhere.
way you can use PSX images is with plugins or convert .bin/.cue +.sbi to .img/.ccd with program from my signature (PSXstuff)
(if you convert, for XOR value enter either one, it doesn't really matter)
