Problem with Super Robot Wars Alpha

[Bruherd]

Hi,

I'm having a problem with the game in subj.
The game is original, but I have a PAL DC and all my bootdisks won't work with it(utopia, gameshark, action replay).

Does anyone have this problem?
Before I modify the DC with a modchip I wish to know if there is another solution(other bootdisks or whatever).

Thanks!!
