If I recall correctly, despite having the same hardware, our rom is very different to the evo rom. We only have about 25% leeway, as 12.5%+ and 12.5%- to play with.
The reason being the evo rom uses different memory areas on the chip for its storage of data, and if we used the same areas, our data would be spread out a lot more as we dont require all the space as the evo does
