A special version of SNES9x with advanced SNES debugging features for real time debugging and tracing. This is a must have tool for more advanced SNES hacking.

This version fixes dma read/write breakpoints, and expands dump support. See the release notes for full details.

Note: If GSD refuses to run, and posts a side-by-side or application “configuration” error, the system can’t find DLLs it needs to run the program. Install the redistributable linked in the release notes.
