Note, "sPatch" web site has been taken down, the maker of sPatch is working on a better version 'hamaPatch', I have a early version of it and it looks nice. If you are looking for "sPatch" you can get it here by anonymous ftp: ftp.32bitcolor.com then the "pub" directory. I got the "sPatch" program from another users site, not the official "sPatch" site, so download and use at your own risk
