Hey guys,
Just took a quick look at the
Flashback Cheatcodes section in HOL
http://hol.abime.net/568/cheatcode
Here's some observations:
... The first set of level codes are for the
French version...
... The second set of level codes should be for the
English +
German versions (thanks to my testing of the Easy level and
Belgarath for supplying the Normal / Hard level codes)
