BlazBlue Cross Tag Battle [DX11]

Helix Mod [Unofficial] May 3, 2026

geo-11 fix for BlazBlue Cross Tag Battle. The game originally runs in DX9, so this needs dgVoodoo to convert the game to DX11.

Fixed

Character sprites, other effects (like Arakune invisibility, or UNIEL character attacks) and HUD are at correct depth too.
Haloing issues.
Automatic low convergence preset for the game hub.

Installation

Before installing anything, make sure the game is running in windowed mode at 1920x1080 , which is the highest resolution you can use without another mod. Fullscreen breaks graphics completely.
geo-11 (with build v0.6.164): download this file and extract its contents in the "BBTAG " folder, where "BBTAG.exe " is. Remember to edit "d3dxdm.ini " to change your "direct_mode" to the output you need. It's set to "sbs" by default and also "upscaling" is set to 1 in that same file.
Install dgVoodoo (v2.87.1 is the version that you need. Different ones may break effects) by copying the "MS\x86\D3D9.dll " file to the folder where you installed the fix. Then run "dgVoodooCpl.exe " to configure dgVoodoo similar to this:

Setting "Mipmapping to "Auto-gen with bilinear filter" improves the image quality a lot since the game lacks mipmaps.

Notes and reminders

Do not attempt to use fullscreen mode. It breaks everything due to some incompatibility with dgVoodoo. Also, borderless mode leaves the game as a small rectangle in the middle when you try to upscale to 4K, so it's best to use windowed mode.
Upscaling is already enabled in the fix, with "upscaling = 1" in "d3dxdm.ini". If you want to disable that, set it to 0.
There is a resolution mod in pcgamingwiki. It has many problems with geo-11's upscaling, so if you have a glasses-free 3D monitor like I do, it's better to not use that mod.
