As i thought, it was not the problem about the difference of the version of the set and mame.... Anyway i've made all at 0151, and same thing! (roms, mameuifx32, cat32, deluxe32...) i think the problem is catver and catlist if i put only catver.ini (version0151 of course) in the line of catver.ini of gameex=> i have no clones! (but no subcategory like vertical fire...) if i put catlist folder (with only catlist.ini) or cat 32 folder, or deluxe 32 (with all the ini.files) in "custom line folder" of Gaamex => all the clones appear any idea at the end?
