It's genuinely one of the best remakes in existence and emulation is not even close in this case because THPS1+2 backports loads of quality of life features from later entries.
About half is from original entries, the other half is contemporary stuff that respects the theme and is very good on its own. It's not the only area where remake gracefully draws from originals and modern skating, for example you get all the old skaters as well as modern pros.
