Galahad : thanks for the precision. This one is really wired because I can't see the point of releasing a game as AGA only and doing so, leaving off the market of ECS amiga owners... At least Jungle Strike, Burning Rubber and Jungle Strike had an ECS version.
Akira : It's just that there is nothing "AGA" in James Pond III. I clearly don't see where there is anything special in that game that make him require the AGA chipset. The only thing I can think of is that the levels are huge, so it make me think the only thing that this game required was 2MB chip ram.
I don't see how can this game could'nt match it for ECS Amiga (and if I record correctly, in the previews, Millenium were speaking about an AGA version with parallaxes and an ECS version without. The final AGA seems to be the ECS one...)
