I'm unable to use any cheats in the Rayman Forever, is there anyway I could possibly?

gamefaqs has a working set of codes, holding tab/pressing backspace aint necessary though, just type in the codes.

Oh I've tried everything, it will not work!

interesting, just tried them on laptop and worked perfectly...you are typing them in levels and not in map screen?

Yea I have been.. that's strange.. Oh well, thx anyways :)

strange indeed, can't honestly think of a reason why they won't work so can't help any further, sorry :(

Hi. I come 9 years after these messages. I've found different codes on the internet for Rayman Forever but not a single one gets activated. Has it evolved meanwhile?

can comfirm the cheats of gamefaq work in general, but they dont work if one of the keys needed is mapped to a movement or action. gamefaq gives two tables, the ones in the first table ("for original Rayman game") work for me but not all and in no appearant order:
for 99 lives "[TAB]bertrand" works,
for fist power up "goldist" works,
for 10 additional tings "[TAB]jojo" works,
for win current level "winmap" works,
others dont seem to work
