How can I go about cracking the Android games that I own?
I own Stardew Valley but I am avoiding using the Google Play store when possible. While I could just sign into Aurora Store with my Google account I think I'd need to install Google Play Services so I am wondering if I could crack the game myself. I think in the past people used Lucky Patcher but I have tried it with other games that I own with no luck.
I've looked through the megathread and it seems like there are versions of Stardew Valley uploaded to Mobilism but a majority of them are modded for things like infinite stamina and money. The version without mods on Mobilism also appears to be re-uploaded from Apk Vision which isn't in the megathread.
If you're willing to learn, look up apktool and ghidra, as well as the Dalvik bytecode reference. Some apps can be relatively simple to crack using one-liner Dalvik modifications. Others may require analysis and patching of the binary libraries. Some Unity games include debug symbols, which can be inspected using Il2CppInspector which makes the binary code easier to understand and easier to find the proper point for a crack. Start by extracting apks, and try something simple like removing the INTERNET permission from the AndroidManifest, to see if the app still works if you rebuild the apk. That improves privacy. After that, try removing more permissions or making Dalvik patches or even binary patches. A great game to start with is Terraria, as it can be cracked purely by modifying Dalvik bytecode. I'm not in a position to help further but felt I wanted to share this for educational purposes. Learning these internals is fun. You can even learn to degoogle your current Android ROM by applying a signature spoofing patch and include microG instead as a replacement alternative to google apis. Hope this helps. 🙂
I had a few legacy apps on the paid store, and everything works on my /e/os without any Google, I'm not sure what does it, but I have Aurora and microG
GeapheneOS (Pixel only) has sandboxed play services by default, with controls over location data, etc. Not sure if that's what you're after but I thought I'd mention it.
Ironically, GrapheneOS is pretty much that (minus the hardware) unless you want to get an iPhone or Windows phone. You'll have to have Play Services to play the games you want to play; may as well use the only sandboxed version afaik. The reason the Pixel line was chosen is because it's essentially what iPhone is for Apple... There will be no vendor add-ons or modifications, just stock android which can be modified into things like GrapheneOS. But it's more for security and privacy than it sounds like you need. Just keep in mind whatever you choose, cracked apps have a much higher chance of containing malware unless you learn to crack them yourself, but then you'd have no time to game.
Since the Play services apps are simply regular apps on GrapheneOS, you install them within a specific user or work profile and they're only available within that profile. Only apps within the same profile can use it and they need to explicitly choose to use it. It works the same way as any other app and has no special capabilities. As with any other app, it can't access data of other apps and requires explicit user consent to gain access to profile data or the standard permissions. Apps within the same profile can communicate with mutual consent and it's no different for sandboxed Play services.
ETA: It looks like there is a modified open source Play Services client called MicroG, which is basically a rewrite of Play Services that allows things to work, but things requiring payments or payments via NFC etc may not work.
I think you just want to play games without play services, not actually learn apk reverse engineering (which is a very complex skill), so MicroG is probably what you want. https://microg.org/
