The SCDS is the only one that lets you modify individual cheats in-game. However, others do have global enable/disable hotkeys that you can press in-game, though these modify all cheat codes at once. If the SCDS is anything like my Supercard miniSD, L+R+Start+Up brings up the cheat menu, L+R+Start+Down brings up the in-game guide, and L+R+Start+left and L+R+Start+right are for global cheat enable/disable.
The SCDS should have 100% Download Play support if you check that patching option, but if I remember correctly that option screws up cheats. If you want cheats, the best thing would be to leave the Download Play option unchecked by default and then simply check it one time if you need it.
