Subject: [PATCH] Fixed Slide Code cheat type

Address increment is a u8 and value increment is a u16. The changes will make this work correctly:-

50000AA4 FFFF
801CC760 0400
which is a example slide code representing:-
801CC760 0400
801CC804 03FF
801CC8A8 03FE
801CC94C 03FD
801CC9F0 03FC
801CCA94 03FB
801CCB38 03FA
801CCBDC 03F9
801CCC80 03F8
801CCD24 03F7
