This particular bootleg ran slow. Looking at the PCB it was evident where the problem was. A 48MHz oscillator had been used in place of the standard 53.69MHz one.
Unfortunately 53.69MHz clocks are pretty scarse nowadays so a cheap 54MHz clock from eBay was used instead.
The board now runs at a much better speed. ^_^
Pics/info of an original board can be found here.
