Loading a manifest.bml file or having a xml file isn't necessary. Just load gamename.sfc.

Here's an example of a working MSU-1 setup done with Secret of Mana MSU-1. Please note that som_msu1.sfc is being softpatched in this example.

BS-X and Sufami Turbo

In order to load BS-X and Sufami Turbo games, you'll need BS-X.bin and STBIOS.bin in the frontend's system directory.

To load multi-cart games specifically, a more complex procedure needs to be followed.

Please note that for multi-cart Sufami Turbo games, you must first run each game individually to create sram files for them. Then the multi-link will function correctly.
