If I got the code correctly, it works in the following way: Computes digest $D = SHA256(password + salt)$ Computes table T with $N=MEMSIZE /32$ elements: $T_{0}=D, T_{i}=SHA256(T_{i-1})$ Set $R=T_{N-1}$ Update $R$ by mixing it with $T_{0}$, $T_{1}$, ..., $T_{N-1}$, where "mixing" is a byte addition or subtraction depending on value of the byte ...

I wouldn't recommend rolling your own KDF. PBKDF2 is easy to implement with access to SHA-256, and with a high enough iteration count will still slow down an attacker, even if not as much as scrypt. From a quick look, it seems that you are walking the memory linearly both when generating the SHA output and when collecting the data output data through ...
