That's useful. I ended up putting a 32K SRAM on a cartridge plugged
into 2/3. Gives four contiguous banks of RAM, 2-3-4-5 instead of
4-5-6-7, but occasionally I find a bit of software that assumes the
RAM is in 4-5-6-7 and can't cope.
Also, I need to make a custom IC header to allow me to plug in my
replacement MegaROM at the same time as the GoMMC. There's a
cruicial 2mm overlap that stops the two of them going in.
