I had a Bowö-O-Rama in my collection but sold it . Why ?!
The HDD is married with the motherbaord over a controlerboard. If the HDD or morherboard or this controller is damaged you have a very heavy brick in your gameroom. There is no way to crack this. I bought for testing also a USB stick with the software on eBay. But the USB stick will not be married with the motherboard and the controlerboard. It bootet but all buttons, coinddoor was not useable.
So I decided for me to sell it as working device for good money, once broken you can trash it.
The morherboard and HDD is available on ebay but you will never get the HDD branded ID to the controllerboard.
The controlerboards were available last year but around 300 dollar.

Maybe this helps fixing yours.
