Quick solution for people that don't care why it works:
Language: lua
local function main()
gui.text(10,10,"hi")
end
gui.register(main)
----------------
DeSmuME is interesting in that it constantly redraws the screen even when paused.
I'm assuming your code looks like this:
Language: lua
while true do
gui.text(10,10,"hi")
emu.frameadvance()
end
The point is that you are using the
gui function once a frame, but the screen is redrawn multiple times per frame.
The solution is to tell DeSmuME that you want to keep drawing when it draws the screen, with
gui.register():
Language: lua
gui.register(function()
gui.text(10,10,"hi")
end)
