Good work as usual =) unfortunately I'm not interested much in TI57 at the moment. Don't stop gathering info tho, it will be useful in the future.
I'm now reading up on the AMI S2000, and will probably start on a driver for Wildfire.

Woops, the .bin does not match the .txt here, it's on intervals of nibbles instead of bytes.

The Wildfire I got was busted. I was hoping it would be an easy fix- most of the time those old games have battery corrosion which can be cleaned up, or a broken wire, but I couldn't get it working. I pulled the chip and tried to dump it electronically, but I couldn't get that going either. So I'll decap it and try to match the ROM bits to the patent ROM dump and see how they differ.
The pinout is slightly different from the datasheet- it looks like VDD was moved from pin 12 to pin 2, and pins 2-11 were slid down one spot. All the other pins seem to be in the right places.

Emulation of Wildfire is showing signs of life. The patent describes that the included ROM data is the same as the commercial release, if true then figuring out bit decoding shouldn't be too difficult.
I think the S2000 on-die 0-9,A-F led7segment decoder is programmable too. Numbers 0-9 are looking fine here, but:
SP shows up as Sb
PL shows up as bd

Is the backdrop in good quality btw? MAME/MESS Artwork guys could make use of a good photo (even better if you have a scanner).

I uploaded a scan of the Wildfire front panel: www.seanriddle.com/wildfire.jpg It's tough for me to scan or get a good pic of because it's one piece with a bend.

Don't worry about that, MAME artwork guys are able to clean the pic up.
Looks good to me, thanks! =)

Is there a real ball in that game, or an LED matrix?
