Currently this isn't checking for contiguous blocks properly, so this patch may break on fragmented SDs. working on it |

Could you also update the changelog (rebase first). The change in patch size is a fix and the dma an addition. |
Previously the main patch (prior to CMD12) was 0x78 bytes, which caused some games to fail to load. It has been split into 2 sections: - IReadSectorsPatchCode entrypoint - A helper function that contains 3 patches: - Apply 0x54 command - Wait for data ready loop - Transfer data loop Additionally, the CMD12 command has been split into its own file, in order to reuse this patch code in the future.

This PR comes in two parts.
Previously the main patch (prior to CMD12) was 0x78 bytes, which caused some games to fail to load.
It has been split into 4 sections:
This fixes most of the issues seen in #111 , except games that require DMA.
Additionally, the CMD12 command has been split into its own file. Which is then used in the DMA patch code, which fully resolves #111.
