In this paper, we study algebraic geometry codes from curves over $\mathbb{F}_{q^\ell}$ through their virtual projections which are algebraic geometric codes over $\mathbb{F}_q$.
We use the virtual projections to provide fractional decoding algorithms for the codes over $\mathbb{F}_{q^\ell}$.
Fractional decoding seeks to perform error correction using a smaller fraction of $\mathbb{F}_q$-symbols than a typical decoding algorithm.
In one instance, the bound on the number of correctable errors differs from the usual lower bound by the degree of a pole divisor of an annihilator function.
In another, we view the virtual projections as interleaved codes to, with high probability, correct more errors than anticipated.
