Multidisc info bytes:
First byte: Unknown, seems to be unused. 00 in known configs (Grandia 3).
Second byte: Discs count (0-9), when 0 or 1 emulator don't enable multidisc mode.
Third byte: Which disc in set is this one (0-8 for discs 1-9)
Fourth byte: That one is optional, but very important. When set to 1,
disc swap menu will be in "Reset game" menu and disc change will trigger reset (default behavior).
But when this byte is set to 0, new option in main emu menu called "Switch Discs" will appear. Emulator change disc without reset.
Keep in mind we don't know how accurate swap emulation is here, games are picky for some details.
Every iso bin enc in set need to have proper data in separate config.
