Nice...can reprogram them in case the firmware goes corrupt apparently.

I'm not a hardware expert but I would guess it is physically possible to upgrade the supercard RAM.  There might be timing issues with the firmware though?  Also, the supercard is SMD (Surface Mount Device) and would be very difficult to hand solder.  I'm personally going to wait for supercard II, or buy M3.

This has been discussed several times in this forum. Everybody has stated that the reasons of why it won't work are:

-Timing Issues (with firmware)
-Power (too much needed, or too few)
-Space and pin layout.
-Noise

So I think it's pretty difficult to do, unless you are a hardware magician (cause an expert may not be enought) but if you still feel like trying, please keep us informed (after all, some people have resoldered SD and MicroSD slots)

You'll need a bit of cash too, seeing as you'll likely ruin a few SCs in the process!!

hmm will ok firmware can be changed .
noise ? what noise ?

isnt the ram so small that it would fit in ?
power hmm well okm cant we make the ram so that we can disable it ? so we would be able to only use it wth the gba couse that one has slowdown. ( or buy a better battery)
