In my oppinion is better is the deletion of coldboot.raf was something optional, so "the user" who installs this mod can decide if deleting coldboot.raf or not
And i think is more simple and less invasive to dont delete it, lets say... if someone asks about how to install the mod or at some point the installation is automated with a tool, the 2 different ways we are discussing could be resumed in this steps:
Option1
1) Replace the rco
2) Delete coldboot.raf
3) Profit
Option2
1) Replace the rco
2) Profit
Option 2 wins, is a shame i could not find a way to achieve it, i was insisting in it because i thought it was going to be easyer to hide/disable coldboot.raf without deleting it
----------
Edit:
Im not counting with disabling coldboot.raf by modifying the .sprx, in my oppinion modifying the .sprx was not a aceptable solution for what i was trying to achieve, because the steps would be like this (more complicated and incompatible with HAN/HEN)
Option3
1) Replace the rco
1) Replace the sprx
2) Profit
