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?
* 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)
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
- removed most of lodepng's optional features
- lodepng now uses the already existing CRC32 code instead of using its own copy
- fixed GIC interrupt priority
