Hey all, I have thought about this before:
I have noticed that the only differences between 64 and 128 mbit F2A carts is the number of chips that is on the back of the PCB, some Intel chips...
I have thought about if it is possible to buy such chips in low quantitys (2), and then stuff them on the back of a 64 mbit F2A cart to turn it into a 128mbit cart!
What do you think about the theory?
I think that it would be likely to work, as the chinese manufactors..is chinese :)

Assuming there is no difference in the ASCI/PLD, yes, then it would work.
But I fail to see the point. Have you checked the strataflash prices lately?

No, URL please?

My eyesight is not so good, so I do all my surface mount work under
a binocular microscope. I've become pretty good with a hot-air
re-work iron and solder paste.
However, there's no way I'd even attempt to mount a Ball Grid
Array package by hand! The chips on my F2A 128M are Intel
F320B3TC "Boot Block" in BGA packages. Ouch!
Instead, I'm going to use the 3.3 V StrataFlash non-BGA series from Intel
on my own board.

PS, "StrataFlash" is more fun to say than "Boot Block" anyday.

I've done quite a few GBA flash cart designs by now. Two of them you can find online on my website:

Thanks ampz.
I am using this cart project as an excuse to finally
learn VHDL. I bought a Xilinx eval board from Digilent to learn
about CPLDs.
This is great fun!
The only problem is that I think I'll have
to buy used game carts and throw away the PCB in order
to get plastic shells for my board!

Used GB carts are cheap :)
