You can download the zip file of the Stable Branch and find / copy the "small-ship-wreck" file and paste it into either the experimental Factorio code where it belonged before, or put it into the Mining Drones Remaster zip and update a few lines of code to reference it.
You can download the Stable . zip on Factorio's website and find the graphic file in the zip file at:
"Factorio\data\base\graphics\icons\ship-wreck\small-ship-wreck.png"
I then placed it in the Mining Drones Remastered zip at:
"Mining_Drones_Remastered_2.1.4.zip\Mining_Drones_Remastered\graphics\mining-drones/small-ship-wreck.png"
You then just need to modify 2 lines of code in the "Mining_Drones_Remastered_2.1.4.zip\Mining_Drones_Remastered\data\entities\attack_proxy\attack_proxy.lua" file to add this new file location.
On line 16:
filename = "__Mining_Drones_Remastered__/graphics/mining-drones/small-ship-wreck.png",
On line 327:
icon = "__Mining_Drones_Remastered__/graphics/mining-drones/small-ship-wreck.png",
Also, to account for the 2.0.35 changes, you also need to update some of the code for the mining drone walking sound. In the "Mining_Drones_Remastered_2.1.4.zip\Mining_Drones_Remastered\data\entities\mining_drone\mining_drone_entity.lua" file, you need to find the code starting at line 161:
walking_sound = sound_enabled and
{
aggregation =
{
max_count = 2,
remove = true
},
variations = sound
} or nil
and replace that with the single line:
walking_sound = sound_enabled and sound or nil
