Yep. It would be ideal thing in case other pcb owners of the game need to find backup data in case the prom data goes sour on a Shark Jaws pcb.

There is already a nice start with some of the Ramtek non-cpu games (Clean Sweep, Baseball, Wipe Out), some non-cpu Atari games, a couple Exidy games, a couple Meadows games etc in which the proms have been dumped.

I don't know if Atari Shark Jaws is one of those that has been dumped earlier. Anti-aircraft, Jet Fighter, Stunt Cycle have been dumped earlier. I am pretty certain Outlaw and Steeplechase haven't been dumped yet.

Non-cpu emulation is somewhat gaining ground here and there. One huge change was last year in which Aaron restructured MAME source code and had various hardware being treated as a "device" and this also included cpus. That was one barrier that stood in the way and now no longer an issue.

There other issues such as roms/proms from various games not dumped yet, paperwork/schematics not yet accounted for, but that is the small stuff
compared to what else needs to be done if ever able to add support into MAME later.

*Adding to what Stiletto already posted ;-) *

I don't have a non-cpu status page completed [Discrete Logistics], but did a reply post
to Stiletto's post of what paperwork that I know of is accounted for. (logic schematics etc.) Stiletto probably has a current updated list.

Keep Juergen's web pages handy because Juergen was getting things started with preliminary TTL emulation. One can download some of the source code and executable files and run some of the non-cpu games that are all-TTL components [no roms]: pong, Space Race, Rebound.

An issue that does presnt a challenge with non-cpu emulation is "Analog emulation"
