Rpatool allows you to run Option 1 from UnRen but doing it all through the command line.
You can also choose to install the dependencies that UnRen itself uses, mainly rpatool and unrpyc.
If you are on a Linux OS or, for some strange reason, using MacOS there is a version of UnRen being developed for Linux/MacOS that you can use. You can get the latest version of UnRen on F95Zone. The best way to learn about it is to test it out for yourself and try all the different options. In order to actually edit these variables while playing you would need to go for Option 3 to enable the console and channel your inner hacker. Option 2 is for people who want to decompile any of the scripts in a game, this is usually done if you want to check out the code and look for variables that might be beneficial to help you “cheat” through a game. This is where Option 1 comes in handy, it allows you extract all the images (and other files) from the RPA packages and enjoy them that way. Some people might not want to grind through a game just to try and get all the scenes and end up missing some of them. Drop it into the folder of a game, double click it, and you’re presented with a wide range of features. Unren.bat is developed by Sam on for the Ren’py engine. If you’re like me, from time to time you might want to bypass the grind within a game, and UnRen helps you do that, and so much more. UnRen.bat is the tool that we never knew we wanted.
