Glitching a write instruction is a little dangerous. But if you have many chips to try or can live with an incomplete, possibly corrupted dump, feel free to do it.
Well, the exploit could be perfected on the device that can be reset first. I understand that writing a wrong address can have unattended consequences, but the read cycle should come first, and glitching likely affects the address decoding circuitry (as opposed to the SRAM registers), so it's probably hard to miss.
I understand wanting to play it self though.
One thing comes to my mind though: each board likely needs slightly different timings.
