>>3250126It's not really that bad. Most of the time, you'll only need the right tool to use to get those pics out. Brands like Lilith and Dieselmine, which uses kirikiri engine only needs ExtractData or Crass to be able to rip everything from the data.xp3 file.
Event CG merging are not too frequent (at least from the games that I get), it's just that it's quite annoying/hassle to do if the game has tons of pics like in the case of Lune. For other games, merging only involves the still character pics/poses.
