nvm found it MStr3am NEMO History

i found another option
instead of trying to disable or hiding extended minimap
i just disabled the map to use the extended minimap"
add map you want to disable under your client
data/exceptionminimapnametable.txt
sample:
izlude_d#
and if you want to change the disable dialog  then go
data/msgstringtable.txt
In this map You can't memorize and zoom the minimap.# <-change this line to whatever you like
sample:
Extended minimap feature is not available.#

case solved:
D2 1D 68 B4 FF B4 00 8B C1  <-look for this line
 
RED channel - CA
GREEN channel - DF
BLUE channel - FB
For example, we want to change it by blue color. We need to modify bytes to:
D2 1D 68 00 00 FF 00 8B C1
