Found that the mame softlist version is a demo version it's in the !Boot file.
Found that with this program :
https://github.com/geraldholdsworth/DiscImageManager
The full version on .hdi file works. ;-)
Got into the shop and into level 2.
I added this to the runcommand to load the .hdi file (on aa5000)
-upc:ide:1 hdd -hard2 %ROM%
(in my script version 274.02 it has been added now by default)
Use !Configure to add an extra ide harddrive (nr 5)
Good luck !
