This game has infuriating issues with blanking the gallery unexpectedly, and the gallery triggers being bugged and swapped and wrongly flagged. I know I can just cheat it to show everything, but it's so disappointing to see your legit progress blanked two thirds into the story. Especially since repeat playthroughs are so dull.
edit:
Attaching the best global save file i could figure out. Had to comb through multiple saves to retrigger scenes, which was maddening for shit like the smuggler chick, because the prerequisite asteroid race S-U-C-K-S. I had races where she won because she zoomed out of the screen upwards when the final huge asteroid arrived. UGH! The brothel scenes simply won't stick even when unlocked. They seem to stick if I trigger cheat on-cheat off, but on restart they're gone again. I don't really know how to get the photo of the chick with different eyes. At least one of the basic photos (the red skin chick) seems to be unlocked by a different photo (the anime eye chick). Also, the Halina relax sex scene sometimes unlocks way before it's actually encountered by the plot.
I just don't get it, why would you reset the global gallery save randomly? I find the game interesting and improving over time on the non-porn side, but it tilts me that the game doesn't respect my progress and actively pushes me towards the cheat menu.
