Seems like CG unpacking now isn't profitable?
I mean, nowadays I rarely see full extracts from games.
And for non-reserve-engineering players it's impossible to extracts CG from the game in original resolution, and only screenshots is available function.
Also many extracting programs from various VNs were abandoned (krkrextract, GarBRO, Crass, arc_conv etc).
Buying resources out of their own pockets, spending energy and effort, with almost no return so that everyone can enjoy the cultural and entertainment products of developed countries at almost zero cost walking in the dark to serve the light, they are real heroes
