Worklog Getting the PS2 smaller

Other than the omitted 16 bit support, looks OK

Since the pins are there, you might as well hook up the 16 bit stuff, and mux BYTE# and Q15 accordingly to /BYTE. That will allow faster accesses with custom drivers

As far as I understand, 16 bit is not used for booting the rom0, right? I guess it would allow faster reprogramming, but that is not really necessary

16 bit is not used in the process of booting. But it will allow faster access r/w with custom drivers.

It may be possible that some chips can only be flashed if the full address/data range is available, but not too sure about this

Looks like this chip can be programmed in byte mode, so looks fine! Thanks for the quick reply. Not really concerned with R/W access, at least not yet
