new road junction

1 : You can try using TMP Builder to create new tiles. The Add Tile function in v1.0 is broken so don't use it. Good luck.

2 : You can't simply name the new roads proad6+ and expect it to show up. You'll have to increase the number of tiles in for example, temperat.ini, but doing so will break all existing maps!
Instead create a new set in temperat.ini with any new filename: proadb01 etc...
