Correct.  The 1986 and 1987 versions.

Not to my knowledge.  The ’87 fixed some shortcomings of the earlier chip. 
Mostly timing errors, though there are differences in the video outputs as well.

It would take a properly configured FPGA to replace the GIME, which is not available anymore.
Such a project is underway and nearing completion.
