I don't have them myself so I can't test but maybe others can.
Flashrom Programmer: Macronix MX29LV320 and MX29LV640 (connected as 16bit flashrom in 8bit mode)
GBA: Intel 4400L0ZDQ0 (Only using the first 32MB)
N64: Fujitsu MSP55LV100S and Macronix MX29LV640 (Fujitsu might have a different sector size)
Almost the same as Macronix MX29GL128E but sector size and write buffer are half the size.
Data pins 0 and 1 are also swapped and it still needs 5V to erase correctly.
The whole GBA code is currently a little bit buggy, so for dumping roms you propbably should stay on the last somewhat stable release V27D.
Reflashing only seems to work with 5V. Probably out of the same reason why some real carts don't work with V28 ... bad read/write timings.
I also might have broken support for the Intel flashrom I added in the last commit...
There is still a bug left when it comes to resetting the flashrom to read mode since I can't find the datasheet to look up the partition sizes. So it might be that the verifying process fails even though the flashing was successful. In this case remove the GBA repro for a few seconds then just dump the rom and compare if the write really failed.
