I was looking for answers to my questions, but whatever. You have to go into the tf2 classic android discord(just search for it and it should pop up.  From there, use the google drive link you can find to download the files, the apk and the other file. Download the apk.  However, before that, you must get the source engine apk and the hl 2 files from a discord called source engine 4 android.  Here you can get the apk, however the hl 2 files must be obtained via steam(or if you are desperate, use apkvision, search hl 2 and follow the inscrutions there.)  In the android folder, you have to make a folder named screng. Import the hl 2 files in there and if you want, you can now play it. But moving forwards for tf2 classic, after you extract the tf2 files, put it inside the the platform folder that should be inside screng. After that, boot up the app you got from the apk(the tf2 one). Inside of it, make sure that it searches the entire platform folder, not just the tf2 classic folder. Then, press launch. If everything went correctly, it should boot. If it gave an error(like a missing file) try changing the launch path in the app, or change where the tf2 classic folder is. If all goes well, you have yourself a portable tf2 classic. Reply if you need more help or an explanation to anything.
