There are games that won't work properly with a 6 button controller (with these games just hold the mode button in at start up) :-
mrs pacman, forgotten worlds,
super skidmarks (no lock and runs in 60hz but is total unplayable at that speed).
The best way to play most games on a console, is to buy a region free modified console, (known as criminal to do to a japanese model as they are highly collectable, and will lose value if done),
a 50-60hz and language mod is needed to play all games from all regions, the best and easiest to mod is a mk1 u.k. european console, it will then also be full screen as well as able to play ntsc games which are nearly 20% faster, also the mk1 is known to have the best audio and visuals (either an av cable or an rgb cable is needed to show colour in 60hz mode, best cable is the rgb with audio jack lead).
will be updating this guide as i go along, as far as know all info is accurate, could poss do with some help in making list more near complete, so if know of a game not listed that has lock just send message and ill ask around to try n confirm it before adding to list.
