I need help cracking a code.?

in standard English, the letters I can think of which may be double include "L", "S","O" and rarely "E". Other possibles include "C", "D", "F", "M", "P", "R" and "T". you can make a similar list of the letters which rarey or never occur double.

it seems plain that the grouping into five letters is arbitrary and intended to make codebreaking more difficult. Note that this means an apparent double letter may actually be two words with the last letter fo the first one being the first letter of the second.

with only 100 total characters, the usual frequency tests may well be weak ["e" is the most commonly used letter in the alphabet, for example, and "E" occurs twelve times in the sample given]

you might try thinking of military related words with unusual spellings and see if they can fit .. example "attack" {which won't fit anyway in this case}. other such words which might occur in a British communication -- Canada or Canadian, India, convoy, division, target, aircraft, carrier, Scapa Flow, London, Holland, Liege, Greece, Russia, etc.

it would help if you'd given us the context ... what is happening in the game?

There's nothing to decode, as that message isn't in code. It's in Welsh. All it's saying is that Lieutenant Jones thinks that Major Patterson is "gayz" and that, recently, Jones entered into a bout of amorous concourse with the Major's mother who was, apparently "great". Hope this helped.
