I tried this one out just for kicks. i had game guys color system but it didn't color names in your item system.
I like both a lot.. but anyway here is what i found.
on line 92
drago_drawitemname(item, x, y,enabled)
"Wrong number of arguments(4 of 3)"
Shops are ok but the equip and status are not is not.
i made the line a #comment and it solved the error.
but it no longer drew the icons in the equip and status pages.
