By replacing only the main.dol in the original PAL rom from the new one and booting the emulator boots to a black screen but doesn't crash you can still use the menu to continue/return to title.
I think the main.dol should be priority.
If you decide to take the easy way out, at least do it some interesting way, like 5 fishing magnets and ropes... Run out to the space x rocket as it's about to take off.... Ohhhh add some snow skiis and skii into to space!!!
