I had entered through the PC emulator just to test it.
I believe in you man, after all you are the hero without a cape who managed to port Nekopara uncensored to cell phones, I too am still trying to understand why the game doesn't want to work at all... I have enough space to download Roblox, Free Fire and Mobile Legends and you'll still have space left... I thank you for the port and for trying to help me, but maybe the problem is just my phone and we're here racking our brains for nothing... I'm a little sad that I can't have the experience of finally playing this uncensored version of Nekopara that I was looking for so much but doing what, right... that's life.
I thought something like an android emulator like VMOS would do the job, but Kirikiroid2 just won't activate its license because it detects android emulators that are inside android itself.
I'm honestly pretty disappointed, the situation really looks practically dead-end.
If you ever find out a solution or ends up working at some point, please let me know.
Very last things to try to see if they somehow fix it:
-Restart the phone, then check if the game works now.
-Close as many background apps as you can, check then if it works.
-Move the game folder to other locations, like in mid of storage/emulated/0/Nekopara/, or in your SD card
-Try not to touch anything on the screen right after tapping on data.xp3 to see if it was something related to tapping right after being opened.
-If you have some sort of experimental /developer GPU functions enabled or enabled hardware acceleration related to your Android's CPU and GPU, disable them.
-Install and try old Kirikiroid2 Pro versions.
