Backporting an addon

I'm trying to backport EMA and pretty much I've backported most of the libraries apart from:
- LibItemUpgradeInfo-1.0
- LibAuras
- EMALibActionButton-1.0
- LibButtonGlow-1.0

Can some more experienced backporter help?

Code:

---

hooksecurefunc("MarkNewActionHighlight", function(action)
        lib.ACTION_HIGHLIGHT_MARKS[action] = true
        for button in next, ButtonRegistry do
                if button._state_type == "action" and action == tonumber(button._state_action) then
                        UpdateNewAction(button)
                end
        end
end)

---

I also don't know how to backport this and

Code:

---

        button.HotKey:SetFont(button.HotKey:GetFont(), 13, "OUTLINE")
        button.HotKey:SetVertexColor(0.75, 0.75, 0.75)

        -- adjust count/stack size
        button.Count:SetFont(button.Count:GetFont(), 14, "OUTLINE")

---

in the EMALibActionButton-1.0.lua

button.hotkey:SetFont(button.hotkey:GetFont(), 13, "OUTLINE")
button.hotkey:SetVertexColor(0.75, 0.75, 0.75)

-- adjust count/stack size
button.count:SetFont(button.count:GetFont(), 14, "OUTLINE")

otherone needs testing. how i found out is just do /frame on a checkbutton then do /print NameoftheButton to see what the frame is holding. (this only works with ElvUI)
