i got a ds tt and when i uploaded the cheats into it they work but for alot of games it will say what the cheat does but then how to use it is cut off and i cannot read what to do. is there anyway to scroll over on the screen or find out what these say?

Idk about other games but for Pokemon it's R + L

try that

but like for two cheats that caught my attention ... cloning us platinum or w.e it says the name then all i see is sel. but i dunno i tried clicking and holding select and it didnt work.
also for shiny encounter it says like go to trainer card then the rest is cut off. so i dunno what to do
