lr-hatari performance

[fumanxu]

Hi

The performance of lr-hatari is very poor. I tested simple games like rick dangerous and the framerate seems to be very low. I decreased the resolution from 640X480 to the minimal, and it seems to be better, but in any case, still unplayable.

Do you know any improvement or configuration that will improve or make playable games? Disabling sound?

This is my config :

Pi Model or other hardware:Pi Zero W

Power Supply used: GPI case batteries

RetroPie Version Used : 4.4

Built From: Pre made SD Image on RetroPie website

USB Devices connected: no

Controller used: gpi case controller built in

Error messages received:
In principle, no error messages received.

Log found in /dev/shm/runcommand.log (if relevant):

Guide used: (Mention if you followed a guide)
I installed lr-hatari from package manager

File: (File with issue - with FULL path)
Not applicable

Emulator: (Name of emulator - if applicable)
lr-hatari

Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS)
Not sure which file is needed... there are a lot in retropie.

How to replicate the problem:

Execute any atari st rom in lr-hatari, performance is very poor, even with simple games.

The RPI zero/1 is not capable at emulating the ST at full speed.
