Grand Theft Auto: Chinatown Wars

[raaaaaaaaul]

I'm playing the game and I have a few issues I believe are emulation related.

I reached a point of the story where I don't get any emails from any contacts (there's no missions for me to continue the story) and also there is a weapon that did not get unlocked at the ammo store. I'm on W10 desktop, not Android.

I can finish the game easily (see attachment below), but there's a little bug in the bomb disposal mission. Sometimes it's so hard to unscrew the bolt and it failed me 10 to 12 times before i finished the mission, and there's a little bug too in the ammunition, every weapon is unlocked, expect the micro smg.
I used ppsspp v1.12.3,default setting, except graphic set to 8x resolution,aniso 16x,rendered duplicate on and vulkan api
