2) There is mention of improvements to superscalar execution which benefit the 68060 as well. Will this update be released? What are the SIMD isolated results when the 68060 executable with superscalar improvements is compared to the SIMD AMMX enhanced version?

3) What is the plan for future SIMD extensions to the ISA? How would floating point support in the SIMD be accomplished without putting floating point values in integer registers with a shared integer/SIMD ISA? How would wider SIMD registers be supported with a shared integer/SIMD ISA? Is the Apollo-core documentation of the ISA/ABI ever really going to be made public? Why are the comments for the SIMD instructions more readable than the assembler instructions and appear alien to the 68k?

About the original 0.50 sources, RiVA was not free until 2014, but there was a demo with some limitations. Then it became free. But still closed-sources. Current status is i asked yesterday the opinion of the author about a public release. I know he is thinking of it and is open to. In itself this is good news.

Sure, there will be a release. We aim this with GOLD 2 release.

About the comments on SIMD instructions more readable ; it is because code use MACROs.

Can't help more on the others questions, quite techy for my knowledge.
