He worked on emulating an abandoned, strange, difficult to get, and 
undocumented hardware, using your 111 patches, and finished it before the wholy 
more experienced MESS team.

He is! xD

Yeah, you said it!
The work is already done, we have all the hardware emulation that Basilisk 
substitutes for hacks.
We only lack the 68k cpu (oh! your patches!!!) and the glue :p

Please don't port Basilisk on top of TCG, I beg to you in the name of some god 
of your own choice :(
(1000 Mb floppies patching .sony instead of implementing SCSI and SWIM, no 
ethernet controller but a working TCP/IP, oh hell, it's not a Mac, it's a 
Match!)
