STM32F103VET6-LinkSprite Spruce (STM32-V2)

Hey All,
I'm new here sorry if I make any mistakes while posting.
I have this board and I'm struggling to get the on-board SD card to read/write, it uses the SDIO. I haven't found any examples using the Arduino IDE for SDIO only SPI.

(using the WayBack machine as their official website is down)
Here is how the SDIO is connected:
PC10-SDIO-D2
PC11-SDIO-D3
PD2-SDIO-CMD
PC12-SDIO-CK
PC8-SDIO-D0
PC9-SDIO-D1
I was able to get the Board LED_BUILTIN (PB5) and Button (PB15) to work with the Arduino IDE using Roger's Version of the STM32F1 Boards.
https://github.com/rogerclarkmelbourne/ ... _STM32.git
The ethernet port and RTC also only seem to be working with Roger's version, the new STM32duino doesn't have the same examples/pin layout for it to work. I will attempt to make a "new variant" to see if I can get this to properly work on the new STM32duino.
In case anyone need the schematic/gerber/bootloader for the whole board. All the files are in the link below.

As a side note I haven't been able to get any of the bootloaders to work so I'm currently using the Serial Interface to upload.
