Summary0006809: An old Issue with the AGA versions of BB, BBG & UBB - Speed fluctuates
DescriptionOh, not again. Team 17s AGA games and there Timing issues. (never really solved)

Body Blows AGA & Body Blows Galactic & Ulimate BB
have fluctuation in the gamespeed, like when you get knocked down, you can see that the "enemy" animations and movements are faster / too fast and vice versa. Blitter synchro is all over the place.

Tooltypes like EXPChip help a little bit but wont solve the basic issue.

This problem affects , Body Blows AGA, Body Blows Galactic AGA & Ultimate BB.
(i just use the ecs versions:)

(thats again, NOT a fault of the Slaves, same behaviour with the originals;
lots of timing fixtures would be needed - thats no fun ! ;)

Who can do this right ?

I suppose that's the classic "game expects 2 vblanks between syncs" issue when the speed makes it 1 vblank only at times.

Its a Combo of the CPU CACHE and real Fast-RAM. (imo)
Some Team17 Games have issues with that.
