A simple external tool for BizHawk that rips sprites from Bulk Slash. To use, make sure bulkhawk.dll is in your BizHawk's "ExternalTools" folder, open Bulk Slash in BizHawk, and then enable the tool (via Tools -> External Tools -> BulkHawk). While playing the game, MISS portraits (and occasionally garbage data) will be written as PNG files to a new "Portraits" directory next to your BizHawk installation.
Currently only MISS portraits (plus Riesen and Chris's portraits) are dumped. Tested using BizHawk 2.9.1.
Install .NET 8.0 (newer versions might work but haven't been tested) and build the solution using dotnet build. The project assumes your BizHawk installation is at "../BizHawk/" (relative to this repo). Besides BizHawk, no other external dependencies should be required.
