[Testers needed] Increased CTRCARD clock from 4.18 to 13.4 MHz on ROM reads. #873

This change significantly speeds up ROM reading by increasing the ROM read clock from 4.18 to 13.4 MHz. This is the same setting Process9 uses. I tested this with 26 different games and all verified successful with this change.

Example: Pokémon Ultra Moon previously verified in a bit more than 31 minutes. Now it verifies in ~19 minutes.

Steps to test:

  1. Boot GodMode9.
  2. Insert the 3DS game.
  3. Open the gamecart drive.
  4. Choose the topmost .3ds file (not the trimmed one).
  5. NCSD options --> Verify file.

Report the result here. If your games do not verify successfully make sure to check with the latest GodMode9 release. Attached is a build with this change.

Tested with Super Mario 3D Land (0004000000053F00_v01.3ds) and Zoo Resort 3D (000400000004B200_v00.3ds) and verified successfully. Seems quite fast compared to how I remember it from the release builds.
