With the new e_text you got the real names corresponding to the new balls included in modpack (roteiro, aerow...)
But you probably wanna know how to rename ball if you change ball with your own texture, isn't it?
In that case you need the tools DKZ studio
ball names are located in
mode_select_e.str --> ID BLOQUE N°&H6030
mo_online_e.str --> ID BLOQUE N°&H7B0
mc_e.str --> ID BLOQUE N°&H50
lcm_e.str --> ID BLOQUE N°&H16570
select the name you want to change, write new name in "editar" window then click on "modificar linea" then "guardar"
sorry but i got the spanish version of this tool
repeat this for each balls.
