Description
Summary
So i've tried to launch Time Traveler with BizHawk but throws an error saying that "this operation is actually limited to compatibility files with a filesize lower than 2 gygabytes."
Repro
- Prepare timetrv.zip and timetrv.chd with the Multi-disk Bundler and be sure the System is set to Arcade
- Save and Run
- Throws the following error in the Output part
Output
(Sorry if you see Spanish text, my PC is Spanish, should be still understandable)

Research direction
Start in src/BizHawk.Client.Common/XmlGame.cs at the loading path that calls File.InternalReadAllBytes, then review the related flow in RomLoader.cs. Reproduce with the reported timetrv.chd file over 2 GB and verify that the compatibility file loads successfully without the size-limit exception.
