Here's some screenshots:
So several conclusions can be made here -
- The sprites are just replaced with blank ones (or hidden)
- Warp data is dependant on acre tile, not on the map position
- You can move!
And you actually have Crypto already - you can battle other Denjuu in the wild with Crypto already! I wonder what the giving of phone number actually does..
You also have your map already, can press Start.
Also, in the actual Toronko Village map without the hacking, the Punica that's supposed to be at the top next to the antenna tree entrance isn't there at the start, but is there after you exit the house (as normal).
Also, in that hacked map, Mr Nerikara was supposed to be in the bottom left hand corner. But he isn't there now!
Another time, when I accessed this hacked map (as in halfway through the game), Mr Nerikara was there as normal, (which shows that sprite data is linked to acre/map data?), but when I tried to talk to him, I couldn't! I just kept pressing A and nothing happened. But why is the event data (if this is as with Pokemon) or the script data apart from the sprite data? Interesting.
And in the third acre of the Toronko Village map (the acre with the shop), the Punica and the man, who are supposed to have light green in one of their palettes, actually used dark green instead! But after I viewed the map and closed it again, the palette changed back to normal.
Another thing: the Punica that you face after returning from the water station actually is on the bridge at this point of time! But why?
Other than all of the above, there seems to be nothing more interesting. But there's endless things to check, but this is enough to find out more information.
