As everyone knows, there are 4 models of drug dealers in the game, but only 2 are used by the game. This simple fix will add two unused dealers (HMYDRUG and BIKDRUG) to the streets, while keeping the ones already present.
The appearance of HMYDRUG is provided in areas consisting entirely of Hispanic (or Asian) population, but there are none in the game, unlike the African American ghetto. However, now the population of Las Colinas and Los Flores will consist only of Hispanics, therefore this will become the place to spawn HMYDRUG. BIKDRUG is a vendor in San Fierro, but is not spawned and can now be found in Doherty and Garcia.
P.S. A similar fix has already been posted, but in my opinion it is illogical, since in addition to disadvantaged areas, merchants also appear where they clearly do not belong. In addition, populations are again affected (Asian areas in the LC, all poor areas of the LC become African American, etc.)
