About the Patch

Sunrise Eiyuutan, developed by Sunrise Interactive, was originally designed without VGA support. This patch modifies the game's executable to force VGA mode, giving players access to crisp 480p image quality on compatible displays.

Key Features:

• VGA Output Enforced: Allows the game to boot and display correctly on VGA-compatible screens.
• PAL Support Included: Fully compatible with both NTSC and PAL console versions, ensuring European Dreamcast owners can also enjoy the game in VGA mode.
• Pure Display Fix: The patch only alters the video output settings. All game data, text, voices, and gameplay mechanics remain completely unchanged.

Installation Instructions

• You will need an original GDI dump of Eiyuutan. Download one of the tools.

• 1. For Universal Dream Patcher from https://github.com/DerekPascarella/UniversalDreamcastPatcher and apply the .DCP patch to the original .GDI image.

• 2. For GDIBuilder v2.1.1 from https://projects.sappharad.com/tools/gdibuilder.html Replace the 1ST_READ.BIN file and use the "Patch a copy" option for all files to build the image.

• 4.  Run the ready .GDI patched image on one of the ODE.

Note: This patch is specifically for Sunrise Eiyuutan (T-41101M). Please ensure you are applying it to the correct game image.
