its not a game update, just one tutorial, maybe it can help to someone development:
i asked several times, but didnt find a way to made less operations for installing vpk to ps vita. usually i compiled game at unity, fixed it with Silica script, then run vitashell, upload vpk via Total Commander, then at ps vita installed game, closing vitashell, run game..at 20-30 times at day its become annoying. so, i found one solution:
1) you need to install plugin
https://github.com/teakhanirons/ftpeverywhere , it runs ftp server at ps vita, you dont need to open vitashell and press "select" to open ftp. also you can install this plugin via autoplugin2
2) then you need to find tool "FTP PS Vita VPK Installer v3.0", last release was at 2016, but it works. you can find it at
https://store.brewology.com/vita/ahomebrew.php?brewid=337 , tool has github page, but its gone now. so, in this tool you need to select vpk tool, write ftp adress and press install, then this tool will upload vpk to your psvita and install it. so, you dont need to open/close vitashell.
i writed to developer, maybe he can give sources of this tool, because it can be improved. it would be great, if tool can run game after install. and if you have another tutorials for this problem - write about them.
upd: i talked with other devs at discord, so, maybe we can make own verison of this tool with new fuctions and less hand work.
