*** The instructions on this page are only for GOTEK Model: SFRM72-FU-DL with the default factory firmware *** *** There are no instructions on this page for use with FlashFloppy firmware. (For Use Only With Roland S‑50, S‑550, S‑330 And W-30 Samplers) I've not tried the instructions in this video yet but it appears to be a sound method for updating the newer GOTEK models To use any instructions and diagrams on this webpage, check with your vendor to ensure your GOTEK contains the STM Cortex M‑3 ICĪlso, if you do end up with a GOTEK containing the new AT Cortex M‑4 IC, you may find this instruction video at the YouTube retrofriends channel helpful.
This newer IC version will not work with the instructions and diagrams shown on this webpage.
March 2021: Due to recent shortages of STM Cortex M‑3 IC's which are used in the manufacture of GOTEK's, some models sold on or after April 2021 will most likely contain the newer AT Cortex M‑4 IC.
