Play Panzer Dragoon Saga with an Action Replay
If you try to play the NTSC or PAL version of Panzer Dragoon Saga on a different-region Saturn console using an Action Replay, a "PLEASE REMOVE THE CARTRIDGE" message will pop up on-screen and the game will not load. Fortunately though, you can avoid this problem if you input the following Action Replay code:
Master Code:
F6000914 C305
B6002800 0000
Cheat Code:
06002EB0 0009
This code has been tested with an Action Replay Version 1.94, and we can confirm that it should definitely allow you to do the following (with this Action Replay model):
- Play the NTSC version of the game on an NTSC-J Saturn
- Play the NTSC version of the game on a PAL Saturn
- Play the PAL version of the game on an NTSC-J Saturn
We would assume that it will also let you play the PAL version of the game on an NTSC Saturn, and we would assume that this code will work with Action Replay models later than Version 1.94 (and possibly even earlier), but bear in mind that these things are currently not confirmed. There is unfortunately no known code that will allow you to play the NTSC-J version of the game (Azel: Panzer Dragoon RPG) on a non-NTSC-J Saturn, although theoretically a code such as this should exist.
EDIT important ! : je viens de re-essayer : les AR 3en1 , 4en1 méme derniere version ne passent pas direct ! les ST-key non plus
par contre certaines cartouches de simple dezonage fonctionnent tres bien !
c'est le cas de la "CD+plus" et du "MULTI GAME ADAPTOR" SS-239 de chez TREND-MASTER
