HELP editing half life decals.wad Thread

Hey, so i was trying to edit the half life decals..
But i can't edit decals using wally..whenever i try to compile it, the game don't recognizes it
At first i tought the problem were the edited images
But then
even if i just export and recompile the original vanila decal files,the same problem happens

In the normal half life engine it just becomes invisible
In xash 3d all the textures loses its transparency(meaning its as big white box)
And i can't find any apps like wally to edit wads
I see a lot of people can edit decals no problem

And i can't seem to find any tutorial on this specific situation
Any ideas on what i am doing wrong?
