Ok, from top to bottom we have:ST M36LDR706 -> The gbxcart-rw project has support for this flash chip so one could take a peek at the source code there and port it over
Intel 0121 -> Can't find any info about it, but if we're lucky it's similar to the Intel4000 and Intel4400
Intel 4400 -> This should already work, maybe there is a bug in the code though, I can't test since I don't have this flashrom
Fujitsu MSP55LV100G -> Again I can't find any info about it, but hopefully it's similar to the MSP55LV100S that is already supported in N64.ino.So one should be easy to fix, one do-able to implement and two will require some serious trial and error. Too bad that they all don't have the same type of chip. I'll probably won't have the time to add support for them.
Ok going by the 4 I listed a few pages back just for reference, the Intel 0121, and the MSP55LV100 refuse to copy. Those other 2 chips appear to work just fine.
