Thanks for the information on the program Lossless Scaling, I managed to find a free version online or update 2.90 of the program. However, I'm not too proud to admit that I don't have a clue how to use Lossless Scaling. There's a whole lot of options to choose from, such as Scaling Mode, Scaling Factor, Scaling Type and so on.
Anyway, I was wondering is you could explain what you have to do to get this program working for hentai games like Sister Travel. I and I'm sure many others would appreciate it, and thank you for your time.
guessing you got the free version 2.9 from the internet archive?
That is just a pirated version of the official program that someone uploaded to github without the purchase checks in place.
It then got taken down.

not so sure how safe the version uploaded to the internet archive is, I'd run it through a virus checker and then double check it doesn't make any network traffic while it's running if I was you.
all of that was just a preface to say:
use this instead if you don't want to pay:

8.5k stars means it's definitely safe and it's also pretty good at what it does.
