I don't think I did anything else than replace the memory chips. The "REU size" jumper (if that's what you mean; I made the updates several years ago) is merely connected to an input pin of the REC (RAM Expansion Controller) chip, and as far as I know, programs should not rely on the corresponding bit in one of the REC registers to determine the size of the REU memory.
