There is something that is causing the bus to hang forever when DMA is enabled.

Use the serial only DiagROM to check that audio will play.

IIRC RetoGameModz has a video with an A600/A500 boot issue exactly as you describe. Worth watching that video.

(Summary the ODD and EVEN CIA select lines were broken in that video)

EDIT: You can use the mouse to move the cursor in diagrom if its actually running.
