I have lots of catching up to do...
All menu screens have been coded, and function identically to those in DKC2: Brigand Barrage:
You may have noticed in the first screenshot that Diddy has a new light blue color palette. If you don't remember, he used his standard palette in two color schemes in the original release--with Normal D.K. and Red D.K.. To remedy this, I paired Red D.K. with pink Diddy, referencing the two playable Kongs in DKC2, and gave Pink D.K. a new Kiddy-colored Diddy as a nod to DKC3.
A few sprites and animations have also been altered:
1, 2. Diddy's odd stances when jumping and standing while holding an object have been fixed.
3. His turning sprites have been ported from DKC2.
4, 5. Both Kongs' mouths in all of their sprites have been altered to use shades of their fur instead of their clothing colors. With the palettes selected in these images, Diddy originally would have a light blue mouth and D.K. would have a white mouth.
6. Slippa's defeated animation is different; it now uses the unused sprites found by Simion32. The animation used when they are launched by the Mini Drums (or whatever the basic enemy versions of Dumb Drum are called) hasn't changed, but you won't see it in this hack.
In addition to what is seen in these screen captures, missing frames have been added to a few of the animations (e.g. D.K. walking holding an object and DIddy's victory animation).
(The sprite and animation changes are already part of a stand-alone hack started years ago. However, several of the animations aren't finished--Diddy's animation while riding animal buddies and Krusha's laugh are two examples--so it isn't ready to be released yet.)
This is probably the last news you'll hear about this hack for a while, as my Spring semester in college has started.
