Help/Support Decrypting IPA of old iOS games

[Veshurik 16 30]

Hello everyone!

I noticed that I have nice amount of old games in my AppStore purchases, that I can't find anywhere on Net. Looks like they wasn't saved at all, etc.

The problem is - I don't know how to decrypt IPA to share it with anyone else. I have iPad mini 1 (iOS 8.1) and iPad 4 (iOS 10.3.4) Jailbroken, but I don't know how I can decrypt some files. 

The situation becomes difficult because I don't need just IPA file, I need to edit some in-game files (usually in-game saves, purchases unlocking etc), because such old games already deleted from AppStore and server purchases down, I can't even "hack" it. And also some games required in-game download content (downloadable from servers, but now servers are down, and content is lost *sob*)

Old games = 32bit games existing back in 2011-2015 years in AppStore, was deleted due to 64bit rules etc. I really want to share old precious games with anyone else, because I love them, and it takes a special place in my heart. 

Thanks for advices! If anyone have Jailbroken iPad on iOS 7-11 (or for some games iOS 4-7), it would be nice if you can test some IPAs that I will try to build (I don't have any programming knowledge, unfortunately).
