I should also mention that I add w/e girl pack I feel like at the time, and I always open the girlsx/rgirlsx file and occaissionally adjust it before using it. Asking what packs people are using won't help you much. The editor offerred is easy to use and very helpful; I think there's an explanation on using it somewhere, I didn't even need a manual, it's that easy. I forget who added the current editor, my apologies to that person.
Edit:The only crashes I get now are the well known quitting crashes, which doesn't cause any problems as long as you saved. The current autosave causes more problems than it solves, don't rely on it; hitting save every time you hit the main screen is a small price to pay to reduce problems until you solve the others. Run your girlsx/rgirlsx files through the editor before adding them and save, even if you don't alter them, if something happened from the file being zipped it'll be corrected. Only takes a second to delete the .BAK file. Pay attention, if crashes happen on a certain girl, make sure all her pics are .jpg/.jpeg. I've come across pics that were renamed as the file type, but the file wasn't actually changed and cause problems for me. One of such cases is mentioned in my first post on this forum.
IrfanView will catch these. Every girl that has caused me a crash problem, running her pics through this has caught a lot of improperly named files. Also, if no alert shows up, just resaving and if it doesn't replace, delete the old file.
As I said before, I no longer have crashes except when quitting. It's a lot of work to start off, but now I have no worries when I play except when I add a girl without checking every pick to see if it's merely been renamed without actually changing the file type.
