i understand, but i changed more than strings/values in resource files...
I'll try to explain what you actually did in a simple way:
Your room light bulb can be either on or off, and its switch has two labels that say "ON" and "OFF" to indicate how the light will be depending on the switch position, as the image:
So if you turn the switch to off, the light bulb will power off, and if you turn it to ON, the light bulb will power on.
So, let's say that you want your light to emit green light instead of the regular white light through this same switch.. Well, you did this:
You erased the "ON" label so now it says "GREEN", and that won't magically make the light bulb to emit green light.
You would need to use a different light bulb that emits that color, or even a different light bulb system with another switch that lets you choose between light colors.
This same principle applies for the DSi CPU overclocking. You can only have 67MHz and 133MHz because those are the only available states allowed by it, and if you want to increase those clock speeds you would either need to use a different CPU or find an exploit that bypasses how that is handled, and the second option requires to make a deep research of the CPU itself, and is not that easy, if it was, it would have been already made.
To add the second alternative, the "find an exploit that allows to modify the clock speeds" to the bulb analogy, a "hack" for that would be to paint the bulb crystal surface with green paint, or put a light filter that blocks both red and blue colors, so only green is visible to the eye.
