Cheats are by no means perfect; sometimes you need to disable them before boss and cutscenes, It really depends on the game and cheat.
In Victory Road I found that the "always have armour" cheat causes the green portals to dysfunction, so make sure you turn it off before walking over a portal (the green mirror slab thing). If you play the game without the cheat: notice that the player sheds his armor when entering a portal - probably so they didn't have to use extra sprite tiles for the entering portal sprites w/armor. With the cheat active, the game is probably stuck trying to get him to shed the armor, so the portal process can't begin.
