How to Initialize Desert Bloom 0.250.0

Hi folks, just updated my sets and loading the new stuff, I keep getting the same problem on several games
"Desert Bloom" for one as example displays (dstbloom)

Memory Error - Machine options

and I can't for life of me figure out how to initialize the games

Looked in MAMEINFO/History but no solution found.

Any ideas on these?

Thanks in advance

It appears these gambling machines are quite complex to set up.

If you look in the source (src/mame/acorn/aristmk5.cpp) there's quite a lot of info of what to do.

Thanks Robert
