Hi Arcade Punks, really hoping someone can help me here im loosing it!

I put together a 3B+ with borken button last year and flashed the image I'm still using now no problems.

I've been trying to get Retrorama V.2 to work for a week and no joy… ( It says it 3b+ compatable)

I formatted my SD to exfat32

I torrented all 97 files sucsessfully

Unpacked it with Winrar 64 bit and have an image.

Flashed it to a Sandisk Ultra 128G using Win 32 disk imager

Booted it up and it goes straight to disk check, when this completes it just hangs and gets no further.

I've repeated this process from scratch ( sd format, torrent, uppack, flash…) five times now and keep getting the same results.

Can anyone advise please as I really like the Image and want all that pre-loaded Dosbox and Scumm goodness ?
