Some help on regex?

Just started out using mod_rewrite and using regex...

[designaweb]

I would like to do some mod_rewriting on the following URL's, but I dont know how :(

cheats.php?action=showtitles&platform=n64&letter=T
Should be replaced by:
/n64/T/

and

cheats.php?action=showcheat&platform=n64&letter=T&title=tony hawk pro skater 4
Should be replaced by:
/n64/T/tony_hawk_pro_skater_4.html

I dont know how to do this...

mod_rewrite is useful to convert fake URIs to real ones that do exist on your server. Producing the fake ones that youŽll be using on your actual html pages is up to you or the script that generates those pages.

Allright, lets put it another way,

A user browses to:

[domain.com...]

But he is not really browsing there, this URL should call for cheats.php?action=showtitles&platform=n64&letter=T

and
[domain.com...]
should call for
cheats.php?action=showcheat&platform=n64&letter=T&title=tony hawk pro skater 4
