Hello everyone I just found a topic regarding a new ps2 emulator being developed called "AetherSX2" made by someone named Tahlreth, an Alpha been released and it's impressive even in its early stages
Link to the developer's page https://www.reddit.com/r/AetherSX2/
U can find the link to his discord channel and link to the emulator which is in google play store on that page.
I have tested Resident Evil Outbreak file#1
And had only minor fps drops overall the performance was good during the time tested with S21
