02/16/14: Modified Discrete Circuity-Based Hardware: Miscellaneous section per the DICE 0.8 release. --
btw: etabeta added quite a few ttl reference files a couple weeks ago so quite a few non-cpu games are now documented within MAME source files at this time. There are still a number of other companies to add later such as Project Support Engineering along with a few others. It's a good start though.

added skeleton for discrete games with roms, to ensure the dumps are available when we get there with the emulation.

// Crossfire // Unclear if this is 100% TTL or if it uses a ROM: // IC description in manual says a rom is used (74186 ROM) // but the parts list in the same manual mentions no IC 74186!
