correct. [David Haywood]

This is a 4-bit parallel resistor (High-Z mos "devices") network

to ground. The result is a non-linear resistance function.

* Added low-pass filter support and opamp/resistor stages to the

pokey driver. This is not as good as complete discrete emulation,

but a lot better than the linear approximation we had before.

Salese]

in emulation but we archive it anyways. [The Dumping Union]

 

- Improved clocks in bankp.c and gyruss.c [Corrado Tomaselli]

 

- Enable proper save stating for bfm_bd1 machine which should fix MT

bug#03990 as well. [James Wallace]

 

- naomi: Make illvelo boot, probably others too [O. Galibert]

 

- model2.c: Updated several sets with Sega's game and / or ROM board
