I have no idea if it's possible but the thought just popped in my head

Could you use AI and Mame to show Arcade PCB fault conditions caused by each or multiple IC failures and match it too your board issue showing most likely IC causing it saving hours of head scratching

I know you could have connection issues and trace faults also but just a thought

Since mame is converting the code of the original game to run on modern hardware I doubt it since it's not emulating the hardware.
Maybe an FGPA with the ability to deactivate certain LS chips in it's core might work though.

Yes, AI can absolutely use MAME (Multiple Arcade Machine Emulator) to diagnose arcade PCB faults, leveraging the emulator's accurate emulation of vintage hardware to identify, simulate, and isolate issues
. While AI can sometimes struggle with complex, non-boilerplate coding tasks, it excels at identifying components, analyzing technical manuals, and assisting with repetitive diagnostic tasks.

AI, combined with MAME, can be used for PCB diagnostics in several ways:

  • Identifying Faulty ROMs and RAMs: MAME verifies code on EPROMs. AI can compare data from a corrupted chip to the known-good code in MAME. AI can also simulate the effect of a bad ROM to match the symptoms on the actual board.
  • Visualizing Signal Behavior (Video Probe): AI can help diagnose graphic issues by using MAME to show specific hardware behaviors. A "video probe" compares output from a logic probe or oscilloscope against expected waveforms. This can be validated against MAME's simulated architecture.
  • Simulating Hardware Faults: AI uses MAME to simulate hardware faults. This allows technicians to see how a specific IC failure might appear in the final video output before attempting repairs.
  • Documenting and Identifying ICs: AI tools can interpret datasheets and identify electronic components (SMD or through-hole) on a board. AI can also map these components to specific locations in the MAME source code to understand their function.
  • Analyzing Input/Output Failures: MAME source code provides a layout of protection ports and input/output systems. AI can help analyze this source code to troubleshoot faulty inputs, such as joysticks or coin mechanisms.
Limitations:

  • AI Reliability: AI can produce inaccurate information or make up details (hallucinations). It should be used as a diagnostic tool, not the final authority.
  • Hardware vs. Software: MAME is a software emulator and may not perfectly represent the electrical behavior of every faulty component, especially analog parts or erratic issues.
For the best results, AI should be used as an assistant for traditional troubleshooting methods like logic probing, multimeter testing, and EPROM dumpin
