At this point I'm a bit surprised that nobody has created a netlist of the board and simply reinstalled the relevant chips on it. There has to be more density that can be eked out for easier that way than carefully taking a Dremel to an existing board.
There are a few reasons for it:
- the cut board is compact enough for most/all hobby projects
- you can get Wiis for very cheap nowadays, perhaps cheaper than the parts themselves
- the original board makes heavy use of serpentine tracks. If they are not just to equalize track length, it’d be very hard to account for all delays in a redesign.
ofc I’m not a part of the community so their reasons might be complete different
