You can skip the diode and polyfuse but:\n- 5V will flow to your device (remember current limit on Aruduino Nano)\n- You will not be protected from accidently reversing power polarity.\n\nYou will gain:\n- much less voltage drop if you want to power the emulator from target.

Q. But why are you using IDC34 for J1?\nA1. IDC34 was used in other popular kit so it's much cheaper vs IDC30\nA2. I had a commercial EMULATOR and wanted to re-use the "probe".

Q. Why SPI EEPROM, you could have used Flash-based main memory instead of SRAM.\n\nA1. This was added last moment, had few spare pins, and thought might be useful to save state.\nA2. Have a commercial emulator based on SRAM and it works fine for the majority of my use cases.\nA3. SPI driver library is built into Arduino and I'm too lazy to write the Flash implementation?? :)\nA4. The SPI section is optional, you can skip it.

Some RESET circuits are tricky to trigger with just a transistor, \nin that case, use a small relay and drive it with this transistor \n(don't forget about extra protection diode if it's not built into the relay already).
