It's using a BASM extension to calculate an offset per the
TSparseList.Flist member and deference and load EAX from there. So given
that EAX points to a TSparseList, afterwards EAX will point to the TList
instance via the FList member.

It's a non-trival change. The parameter order to instructions is often
different and the sizing is all explicit.
