Okay, so I downloaded ATack from
http://hackromtools.altervista.org/a-tack/ . The file says it's a .7z . I thought I unzipped it (like BlackDog61 told me to), but it turs out I was thinking of another download. When I right click the download, the option to extract isn't there. When I double-click on the program to open it, it tries to open with AdvanceMap and "ERROR: (EUnknownRomType) AdvanceMapError(12): Unknown Rom Type! This Rom cannot be edited with AdvanceMap." pops up. The first time I tried opening the program, I wasn't paying as much attention as I should have been and I hit a button without meaning to. After I hit this button I realized what had been on the screen: a pop-up asking me what program I wanted to use to open ATack with the box for "always open with" checked. I have managed to figure out how to not only open ATack with another program, but change it so that it stops trying to open with AdvanceMap. However, I don't know what I should use to try and open the program. I am wondering if I got a faulty download or if I'm missing the program I'm supposed to be using to open ATack since the options I have under "Open With" are: AdvanceMao, Internet Explorer, Windows Store, NotePad, WordPad, Paint, Windows Media Player, and Adobe Acrobat Reader AC.
Rotwang: You have to understand that I'm really weird. Things that make sense to most, make no sense to me. Things that make no sense to most, make sense to me. Using AdvanceMap and XSE I have already changed the maps from Pallet Town to Varidian City and am working on the scripts. I just don't have a clue how to make ATack work which I think I need to do if I want to be able to do what I'm planning on with this hack.
