Ys US Master System FM sound patchDescription

Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)

Note that the hack is incomplete but feel free to enjoy the hack as-is.

Improvement patch readme

The Japanese version of the Sega Master System had vastly superior sound hardware called the FM Sound module that was stripped out for the US and Euro releases of the system, thus any games that utilized that hardware had inferior sound when they were brought out in the US and Europe. In Japan the module was originally an optional upgrade, so all Master System games that used it also supported the regular sound chip incase the player only had a stock SG-3000.

A few US games will play FM sound if they detect the hardware (for example, Miracle Warriors and Kenseiden will play FM sound if you enable it in an emulator or use a flash cart on real hardware), but most had the capability removed. This patch adds the FM sound back into Ys, which I believe is one of the best things about the game. The arrangments on the Master System version are amazing, and the drums the FM sound module produces are incredible.

I also changed all the names back to their proper Ys names (mainly just all instances of ARON instead of Adol and DEKT instead of Fact, but also a few other minor ones). In addition I changed all names from ALL CAPITALS to the Normal Way of capitalizing names.

You should apply this patch to a US/EURO rom, the one usually labeled Ys - The Vanished Omens (UE) [!].sms or some variation thereof.

If you find any oddities that I missed, please email at and I'll fix them.
