Hi everyone. I'm concidering putting HDMA effects into my hack (mostly water and lava effects). I have used it before but I'd like to hear other peoples opinion on it. I have heard of problems with it, but never the less, what do you have to say?

PS. If I've posted this in the wrong section, please forgive me and move/lock if necisary.

This is the right section if it's an SMW hack; otherwise, it goes into ROM hacking.

As far as SMW goes, HDMA effects are usually fairly safe assuming the underlying assembly code (the one that sets up the registers, tables etc.) is. It might become a source of trouble when it collides with other effects on the same channel... I vaguely remember channel 3 HDMA effects creating non-fatal glitches when they were triggered together with the circular close in effect of levels ending (which, iirc, sets the window left and right boundary per scanline to create the circular shape).

	HDMA is a great addition to any hack as long as you don't overuse it. ____________________

Although I don't really care for the seizurific gradient overlays, the ripple effect is quite nifty and it really accentuates a nautical feel when creating an underwater level, also great with hazy desert levels.

Water ripple effect can confuse a lot of people since they think the edge of the cliff/whatever ends to a certain point, but with the HDMA effect waving it you have no idea where it starts and ends. It can also confuse the Urchins.
However, they make a great parallax cloudy sky effect.

...wait, wtf?

The HDMA effects are only graphical effects (unless the maker of the HDMA kit was on drugs, alcohol and under alien influence), meaning that there are no gameplay changes.

It is...?
I could've sworn I played a hack with underwater HDMA effect and having a hard time predicting where the Urchin turns next in the narrow passage with the massive twist twist bend ripple effect.
