Nordic Power and Atomic Power are Action Replay clones which apparently were available in german speaking countries only.
Power Series
Atomic Power 1.1 is a 100% copy of the Nordic Power with just the name and colors changed. No signs of the commercial availability of Atomic Power were found and the "Frank&Joe" copyright hints for a custom text hack on the eprom. There is no ROM available for the Action Power Cartridge 8.1 and the Action Gear yet but the current Power line of products likely looks like this:
- Nordic Power v1.0 (c)Copyright 1989, D&E,Venlo
- Atomic Power v1.1 (c)Copyright 1990, Frank&Joe
- Nordic Power v2.1 (inofficial? This 64'er review has a screenshot stating 2.1)
- Nordic Power v7.2 (c)1989,1991 Gameworks, Ltd.
- Action Power v8.1 (c) 1989-1994 A.S.I. Ltd., UK
- Action Gear (german review)
Thanks to Graham for the 8.1 ROM dump!

ROM Description
Nordic Power is likely based on the 4.x series of the Action Replay with quite a few changes which could only be done with the source code available. The jump from 1.0 to 7.2 sure was due to marketing reasons and making up a number higher than the 6 the Action Replay was going by at the time. The Nordic Power 7.2 ROM was changed to some extent but on many things appeared more to be moving code around and fixing a couple of small glitches. Investigations here are pending, but no new options were found so far. The update to Action Power 8.1 introduced a feature on the freezer named Timerstop. Investigations on this one are also still pending. :)
There are two slightly different Nordic Power 1.0 ROMs on the net. The change does not affect workability or fix bad emulation though and can be dismissed.
All versions replace spr/spr and spr/bkg with "LDA/X/> #$00 ; NOP ($EA)" when running the sprite collision killer on the freezer. Thats just fine, but the told occurences seem doubled. There is no Pokefinder on these cartridge just an options to enter pokes.
