- Select the
DiagROMfile inside the DiagROM 1.3 zip file. This file matches the A500/A2000 512KB layout required by the emulator. - Rename the file to

You don’t need byte swapping or conversion; the DiagROM file is ready to use as-is with the SidecarTridge Kickstart emulator.
Copy DiagROM to the SidecarTridge Kickstart emulator
- Connect the SidecarTridge Kickstart emulator to your computer using the USB-C cable.
- Open the
ROMEMULvolume. - Copy the
DiagROM.rom1.3 ROM image file to the root ofROMEMUL. - Edit
DEFAULT.TXTand set theDiagROM.romfile name as the default ROM. - Edit
RESCUE.TXTand set theDiagROM.romfile name as the rescue ROM (optional). - Eject the
ROMEMULvolume safely.
Always eject the ROMEMUL volume after copying files so the emulator reindexes the ROM list.
Boot and run diagnostics
- Disconnect the SidecarTridge Kickstart emulator from your computer and connect it to your Amiga.
- Power on the Amiga.
- DiagROM should boot directly and present the diagnostics screen.
- Use the on-screen tests to check RAM, CPU, and custom chips.
If DiagROM does not boot, confirm the ROM image is 512KB, re-copy it to ROMEMUL, and ensure it is selected as the default ROM.
