 =========== BUGS =================
 
+- it seems like on arduinos tiny maps can't be loaded (say "FAILED") even if in
+  theory they should (enough block space to load): try to set the exact same
+  settings on PC and see if the maps load or what
 - replay loading BUG! somehow map2 replay was saves with hash 05ef0ab1 instead
   of correct 3c5ba5dd once, WTF, check where hash gets modified
