48d8c48d12 Completely refactor SPI.h, write CTR flash 
Also (hopefully?) write Art Academy, and also implement sector-based
write on Sanyo 256K chips.

fa741b265b Write support for NTR saves 
Why does this work? We are writing flash memories without erasing them,
and writing pages without regard to alignment. Yet it works?

7b0a101f13 Add read support for CTR cartridge saves 
I have done nothing, however, to decrypt them. There is also no write
support.

f60a4c1f63 Add a vfile to show the JEDEC id for the inserted cart 
This is meant to replace the Prompt I was using previously.
Fun fact: WarioWare DIY seems to have *something* on the SPI bus, as it
returns an ID of 0x000001 consistently. Or am I just glitching the
parallel flash? Or did I get a fake?

556c75c337 Fix many bugs by simplifying SPICARD init 
* Fixed card reading (I didn't notice I broke it)
* Fixed cart swapping
* Still unsupported: CTR carts
* Still hangs if cart has no SPI flash (see WarioWare DIY)

The initialization code was simplified to only enable the SPICARD
interface, which assumes the *TRCARD interface has been initialized
beforehand.
To keep things simple, I just wrapped SPIWriteRead with SPICARD_Init and
SPICARD_deinit (which does the exact opposite)

ac4ec6ee90 spicard.h: use void* pointers 
First initialized cart reads correctly now, and cardswap just hangs.

2ceafc545b First viable(-ish) prototype 
For some reason (messed up memory access?) the first two time I read the
status register, I get garbage.

Also:
* Reinserting card breaks SPI (everything reads 0xff
* No support for CTR carts for now
