There has never been an SH3 version thus far, since ShadowMaster's original version of WinWatch was written for H/PC 2000 devices. ShadowMaster didn't create H/PC Pro versions; instead cmonex has hexedited versions that work in H/PC Pro. However, since ShadowMaster has been a regular on this site in the past, maybe he'll be willing to take a shot at making an SH3 version for H/PC Pro.
