# 1. In map.json files, convert "dest_warp_id" to string value instead of integer. 127 becomes "WARP_ID_DYNAMIC". 126 becomes "WARP_ID_SECRET_BASE."
# 2. In map.json files, convert "dest_map": "MAP_NONE" to "dest_map": "MAP_DYNAMIC".
# 3. In all script files (.inc and .pory), convert MAP_NONE to MAP_DYNAMIC.
# 5. In all C files, convert MAP_NUM(NONE) to MAP_NUM(DYNAMIC).
# 7. In all C files, convert MAP_GROUP(NONE) to MAP_GROUP(DYNAMIC).
