3 ways to play.
1) Scds1 os with cheat code... just find the code and make an .scc file yourself it dead easy, heres an example (code won't work)
@crack fix
12345678 12345678
12345678 12345678
etc etc
copy and patse it into a .txt file, then with the sc tools covert the .txt into an AR file and then to an .scc
2) With the tripple OS system use DSTT menu and grab Narin's latest usrcheat.dat and put it in the TTfolder, enable cheat and play
3) Yasu menu (Tripple OS setup), again you can use the latest usrcheat.dat which goes in the TTmenu directory, enable cheat and play.
note, you can also covert the latest usrcheat.dat file to .scc files very easily and quickly
