There is HQ Aerith in the bootleg and once bootleg 0040 is out ( as 0039 has a bug with Tifa and Yuffie ) you'll have better models for Tifa and Yuffie too. There's a HQ model for Red13 too. Other than this, you can learn yourself how to rip models from another game, convert them and implement them into ff7, but this forum won't be supporting that
