Don't worry, I found the script I was looking for:
function displayGrowths()
growth = memory.readdword(0x3004E50)
growth = memory.readdword(growth)
HPgrowth = memory.readbyte(growth+0x1C)
Strgrowth = memory.readbyte(growth+0x1D)
Sklgrowth = memory.readbyte(growth+0x1E)
Spdgrowth = memory.readbyte(growth+0x1F)
Defgrowth = memory.readbyte(growth+0x20)
Resgrowth = memory.readbyte(growth+0x21)
Lckgrowth = memory.readbyte(growth+0x22)
gui.text(8,48,"HP: " .. tostring(HPgrowth))
gui.text(8,56,"Str: " .. tostring(Strgrowth))
gui.text(8,64,"Skl: " .. tostring(Sklgrowth))
gui.text(8,72,"Spd: " .. tostring(Spdgrowth))
gui.text(8,80,"Def: " .. tostring(Defgrowth))
gui.text(8,88,"Res: " .. tostring(Resgrowth))
gui.text(8,96,"Lck: " .. tostring(Lckgrowth))
end
gui.register(displayGrowths)
