now i just need sanitize it

[GoatonicReal]

uhmm- its not giving the opt to do so ~w~"

[anonberry]

@GoatonicReal where did you get the file?

[PanConChancho]

@GoatonicReal looking at that report, the file looks clean, just a lot of advices but nothing bad

[GoatonicReal]

@anonberry i got it here https://forum.ripper.store/topic/32597/lf-bvnny-by-basedvulpine/40?_=1777440297583

[GoatonicReal]

@SummerTYT ahh oki i see,so its fine just be careful basically?

[PanConChancho]

I've already updated the program; there are now fewer false positives compared to version 10 of poiyomi. I've also added a command to export a ".unitypackage" as a folder/zip file.

I also fixed the problem where the version wasn't displayed correctly when using the program (thanks @anonberry).

Those who know how to use the terminal can extract the Unity packages; I will include an interface for this soon.

[PanConChancho]

@GoatonicReal Usually when is only "Low" flags, then is safe

[GoatonicReal]

ahhh oki i getcha, thank you for the updated version ^^
was wondering why it was showing "0.4"

[GoatonicReal]

also for that file, should i just stay clear of it? or (just a lil dumb)

[PanConChancho]

@GoatonicReal That unitypackage you have it should be safe to use

[ManMachine]

the latest poiyomi pro I got showed high risk, I don't know if I can use it:

@ManMachine Poiyomi models are known for having a high number of scripts, it's more likely to be a false positive than being malware. The scanner should be updated in a near future to improve detection in poiyomi models.

[PanConChancho]

@ManMachine As @anonberry said, it's more likely to be a false positive, in the latest poiyomi version (v10) they implement more stuff that isn't the version 9 so I have to update

[ManMachine]

perfect, ty. I can use them without worry, then
