Okey, I got really strange errors with editing SoulSilver in PPRE.
I basically changed only what Pokemon do appear on each route, that;s all.
Now it seems that events on these routes result in my No$GBA showing "Microfon failure" error.
For instance, event on Rt 34 (with ethan/lyra showing his/her grandparents) causes this, and the guy on Rt 31 giving Apricorn pouch makes the same error. However, the Farfetch'd event doesn;t do anything even though and I changed ilex forest data.
What can cause such problems?
