After nearly 30 years I still remember the best cheat for the Amiga version, Marks Team, which basically unlocked everything in the game and let you just have fun once you've played through the game.

I bought this expecting to be able to relive my younger years, playing with 100 million credits and fully maxed out agents again, but sadly the original Amiga version cheats aren't in this build.

Nostalgia crushed.

You can use different cheats to achieve that effect
"To The Top" as company name will unlock everything
"Rob a bank" will give you lots of cash
"Watch the clock" accelerates time

There are others like
"Own Them" or "Cooper Team" for some other specific effects
