'''Nordic Power''' and '''Atomic Power''' are [[:Category:Action Replay]] clones which apparently were available in germany only. Not even rip offs or hacks of this one have been spotted as of yet. Please feel free to supply your own. All ''Nordic Power'' notes apply to ''Atomic Power'' as well.

''Nordic Power 1.0'' is a 100% copy of the ''Atomic Power'' with just the name and colors changed. It appears they were forced to change the name for some reason. The only assumption this is based on is the existence of the ''Nordic Power v7.2'' dated 1991 though.

Basically there is just one ROM available. The two versions found on the net actually contain a 3 byte difference only. Interestingly these 3 bytes are at offset $4000 of the ROM, representing pointer information (CBM80 pointers). Now the confusion starts:
''Nordic Power'' is likely based on the 4.x series of the [[:Category:Action_Replay|Action Replay]] with quite a few changes which could only be done with the source code available. The jump from '''2.1''' 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. :)


* ROM no.1 contains EF FC 0C at offset $4000 leading to $FCEF and $800C as pointers.
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.
* ROM no.2 contains 0C 80 09 at offset $4000 leading to $800C and $8009 as pointers.


The '''Atomic Power''' is using the ROM no.1 as base, while I regard no.2 as "correct". All Action Replay carts have the no.2 pointers and they make sense after all. So how come there are two Nordic Power versions around? To be honest - we have no idea. Our best guess is that someone ''fixed'' the pointers and spread a crt then while the no.1 pointers were introduced by the creators of Nordic Power. This makes sense due to the fact that the bank 2 (offset $4000 - cart is 4*8kb banks and I number them 0 to 3) pointers are not used on Action Replay (hope to recall this correctly).
All versions replace spr/spr and spr/bkg with "LDA/X/Y #$00 ; NOP ($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 [[:Category:Pokefinder|Pokefinder]] on these cartridges but an option to enter [[Pokes_(Explained)|Pokes]].


'''Important Notice''' would be that '''''Nordic Power'' hardware''' can be used with standard 4.1 and later [[Action Replay]] ROMs including '''v5.0''', '''v6.0''' and hacked versions.
The hardware allows a 16kb ROM banking mode which could even be used to play games using that configuration, but they would require patching and possibly even more attention. This 16kb mode is not available on ''Action Replay'' hardware. The original hardware also carries a '''Datel''' writing and differs only slightly from AR v5 hardware.

Nordic Power and Action Power are Action Replay clones which apparently were available in german speaking countries only.

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 2.1 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/Y #$00 ; NOP ($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.

Important Notice would be that Nordic Power hardware can be used with standard 4.1 and later Action Replay ROMs including v5.0, v6.0 and hacked versions. The hardware allows a 16kb ROM banking mode which could even be used to play games using that configuration, but they would require patching and possibly even more attention. This 16kb mode is not available on Action Replay hardware. The original hardware also carries a Datel writing and differs only slightly from AR v5 hardware.

Notes

  • Extensions for Action Replay should work. If we run across incompatibilities it will be stated there.

    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)

    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
        and Cart RAM (Bank 0) is is enabled in io2 area
        using 16K Game config

           cart RAM (if enabled) or cart ROM
