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 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 amount of occurences told to the user often is doubled for some weird reason. There is no Pokefinder on these cartridges but an option to enter Pokes.
Notes
- Category:Extensions for Action Replay should work
Tech
The following is shamelessly ripped from atomicpower.c from the VICE emulator. Text was written by Groepaz:
- the hardware is very similar to Action Replay 5, with one exception
32K rom, 4*8k pages
8K ram
io1 (writes)
7 extra ROM bank selector (A15) (unused)
6 1 = resets FREEZE-mode (turns back to normal mode)
5 1 = enable RAM at ROML ($8000-$9FFF) &
I/O2 ($DF00-$DFFF = $9F00-$9FFF)
4 ROM bank selector high (A14)
3 ROM bank selector low (A13)
2 1 = disable cartridge (turn off $DE00)
1 1 = /EXROM high
0 1 = /GAME low
different to original AR:
if bit 5 (RAM enable) is 1,
bit 0,1 (exrom/game) is == 2 (cart off),
bit 2,6,7 (cart disable, freeze clear) are 0,
then Cart ROM (Bank 0..3) is mapped at 8000-9fff,
and Cart RAM (Bank 0) is mapped at A000-bfff
using 16K Game config
io2 (r/w)
cart RAM (if enabled) or cart ROM
Missing
- Action Gear ROM dump
- Expansion disk images
- Manual scans
- Box fotos
Binaries
Nordic_Power_binaries_rr.c64.org_2010-04.rar contains just the C64 binaries:
- Nordic Power v1.0 bin
- Atomic Power v1.1 bin
- Nordic Power v7.2 bin
- Action Power v8.1 bin
Nordic_Power_all_rr.c64.org_2010-04.rar contains:
- N/A
Trivia
- Backup asks for 1541 35 and 40 tracks and 1581 but crashes on VICE (testing required!)
- The command CBM hints for 5.x Action Replay series
- Nova Load file transfer hints for pre 5.x Action Replay
- Loader saving crashes - asks for enhancement disk before - but loader seems in ROM?
Weblinks
- German CBMHardware page - alas - the linked MK.gif is not correct and cannot be the same as the Nordic Power
