Turrican 3 does that (and using 8 way sound channel too).
But this is probably one of the most optimized 512kb game made on the Amiga (and in only one disk !).

amiga people love to ssay this but all turricans that have tfmx audio only use 8 channels on the title screen you cant do 8 channel software audio mixing and keep it speedy on a plain ocs/ecs machine

Your right, but it might be possible now, depending on the game:

Ahh you cut it before you got the flaming sword, you tease.

Excellent conversion, Love the music as well, hearing that bass wave wobble.

Any reason why you choose Vimeo over youtube?

Well it does have music/sfx/parallaxes and fits in 512kb ram machines and just on one disk.
Based on your pseudonym, you should be aware that Turrican 3 is a coding masterpiece.

it will come as a surprise to you that someone like me can love something a lot without resorting to make up fake stories of grandeur about what i love just to make it more valid my point still stands youre wrong turrican games do not have 8 channels of audio going when the actual game is playing

That doesn't change the fact that Turrican 3 works on any 512kb Amiga and have parallaxes, music and sfx.
That said Mikel was maybe speaking about the limitations of the Scorpion Engine itself.

No, Turrican 3 needs 1 MB of RAM, Turrican 2 needs 0.5MB of RAM.

Nope. Cf : https://hol.abime.net/1537/boxscan

"For all Amigas, 512k and above"

Wrong info. Try to run original Turrican 3 on Amiga with 0.5 MB RAM and You will be see requester. I had access to original T3 for WT crack.

[sokolovic]

That would mean that both the game box and the manual are wrong. Very strange.

Or maybe im remember something wrong after 30 years. Maybe this is only bootloader problem, which checks for 1 MB, because for WHDload, only 0.5 MB of chip RAM is necessary.

Both IPFs in TOSEC work fine with only 512k of chip RAM (and no other RAM).

Update time, wohoo!

I don't know why but I really like the gradient effect on the backgrounds, SNES-style

For me this the true Amiga signature.

Really nice update.

I guess if you've got room, you could use a sprite and make a moon in the background in the top left to add to the parallax effect, or maybe some stars?

[TCD]

Just had a quick go and it looks and plays pretty well for an early alpha Only thing I noticed is that getting off ropes/lianas isn't that intuitive. Is there a proper way to do it (pressing left or right and the fire button doesn't seem to work)?

Can't do it sadly. The copper effect is its own isolated thing that you can use for color gradients, but not for gfx elements beyond that. And I'm out of sprites/memory for any kind of real parallax.

Oh crap, I forgot to look at the whole 'second button to jump' situation. I'll make a note to include left/right + 2nd button to jump off in the next update For now, the way to do it is to hold left/right and then press up to jump off
