Fix for Giana homebrew port

[MushGuyDS]

Flashcard or Exploits? Flashcart, DSi (via Unlaunch), and 3DS (with Luma installed) Base Console: DS, DSi (latest firmware), 3DS (latest firmware)

TWiLight Menu++ Version: Still present as of v27.12.4 TWiLight Menu++ Theme: Nintendo DSi theme

Expected behavior

The bottom screen should show up correctly as a black screen with text.

Actual behavior

Several white parts on the screen where it should be black

Steps to reproduce

1. Load giana.nds (obtained from here) on flashcart version.
2. Load giana.nds on both DSi and 3DS versions in direct mode, not through nds-bootstrap.

Notes

A fix for it, related to VRAM, was implemented to akmenu-next as of v1.3, which loads homebrew in direct mode, so the same fix should work with this frontend as well.
