The only way that you can change the hardware DIP switches (Hard DIPs; the psysical switches on the arcade), through is to use either the Debug BIOS or the Universe BIOS. The switches reset when you reset the emulator. These DIPs are marked 1-1 through 1-8, and 2-1 through 2-8. You can alos enable the so-called "Developer Mode' as well. Don't ask me what it does though. Software DIP switches are the ones that can be accessed through the Neo-Geo Test Menu; (F1 in NeoRAGEx, F2 in Nebula, Kawaks, MAME, B+C+D with the Universe BIOS) ---> Setting Up The Soft DIP--> ) These settings control the amount of rounds, difficulty, blood on/off, language, etc.
