How to port from GTA IV without SparkIV?

I heard that you need Spark IV to port from GTA 4 but I wanna know if I can get the models and textures without Spark. Spark is a broken piece of shit, it never works right for me

Nope. Spark IV.

Fuck, Spark never works. It keeps saying my game is unupdated or modified even though I just installed it

Well you probably need to update your GTA IV then.

Whats the newest one?
