Kudos to what Adam B. has been doing regarding DICE this year and also credits to Tingoes [Guru too] for the Stunt Cycle pcb from years earlier in why Stunt Cycle is running in DICE.

For this year, it has been a good start so far after Couriersud's summer contributions got things started for preliminary non-cpu support. Other non-cpu games should eventually be supported, but it will be a while.

- Implemented a generic implementation to model discrete net lists.
[Couriersud]
* Based on timeslot modelling, the implementation models gate delays
in logic chips.
* Design ready to be split into a generic and a MAME implementation
part.
* Design prepared to merge in discrete components from discrete.*
* Supports code based as well as external net list parsing.
Ultimately, net lists and discrete emulation should share one code
base. The class design was set up to accomplish this. There is no
point in having multiple 555, 7474 implementations around. Most of the
code will be moved to lib/netlist going forward to allow usage in
other projects.

- Pong now uses netlist.h. This implementation reproduces all gate
timing and 555 related effects as described by Dr. H. Holden in his
2012 publication "ATARI PONG E CIRCUIT ANALYSIS & LAWN TENNIS".
[Couriersud]

-Updated netlist implementation: [Couriersud]
* Now supports any resolution fitting reasonably into a UINT64
* Execution now uses a list sorted by execution time
* Implementation now supports analog and digital inputs / outputs
* First step in a move to "terminals" being both input / output
* Improved object model
Pong:
* Rewrote video code, now emulates a monitor by analyzing the analog
video signal and identifying vsync and hysnc pulses.
* Removed all hacks.
Overall performance increase of about 10% over the previous "pongf"
implementation.

There is an old thread if wanting to see what remaining (emulation bug related?) issues there are concerning emulation of Pong.

It's odd that Pong works on every computer except mine. Short of formatting my hard disk drive, I have tried everything I can think of. I recently experimented with borrowing an lcd display and ran pong with lcd display while my old crt monitor was unplugged and sitting over to the side. Even the lcd display had exact same visual behavior as my old crt monitor.
