Always wanted to know how it would be to play Donkey Kong in reverse???
It is now possible with the rom hack Donkey Kong Reverse.
In Donkey Kong Reverse, jumpman starts the barrels stage, conveyors stage and elevators stage at the top of the screen and has to grab Pauline's heart at the bottom:
- Imaging running down the girders while being chased by the barrels behind you in the barrels stage.
- Or trying to evade the bouncing springs while trying to ascend the top ladder in the elevator stage.
- Or trying not to be grabbed by Donkey Kong at the top conveyor in the conveyor stage.
And in the rivets stage, instead of unplugging the rivets, jumpman has to plug them back in. Instead of the tactic in which you try to lock the firefoxes at one side of the screen, they are already locked when they spawn. And by plugging the rivets in, you free them and enable them to start roaming the screen.

Besides the reversed gameplay I've tried to keep the game as close to the original as possible. However, to increase the gameplay, I had to make the following adjustments:
- In the barrels stage, barrels do not disappear when they roll off the edge of a girder lower than jumpman's position.
- In the elevators stage, the first bouncing spring starts immediately instead of waiting a few seconds.
- In the conveyors stage, jumpman is able to walk on the top conveyor belt and dies when he touches Donkey Kong.
- In the conveyors stage, firefoxes spawn from the oil can at the side opposite to jumpman and are more freely roaming.
- In the rivets stage the end of level animation no longer displays collapsing girders.
- In all stages it is a little easier to jump fireballs/firefoxes: they do not change direction when jumpman jumps them.
Hope you enjoy this rom hack.

Wow! Very cool! <gasp>

This is surprisingly awesome WOW

ok played it for a while and first impressions.
1. Definetly unique.
2. I notice how you cant jump at the top of the barrel stage.
3. Its hard to get used to if you are a DK player. The "reverse" rivets messes with you at first.
4. The elevator/spring board requires undoing everything you know but once i figured it out was once again the simplest board in the whole game :D
5. Jumping fireballs is a lot easier but they freeze an abnormal time now.
6. Dont forget to steer barrels "Away" from you.
7. Overall pretty fun I may actually try for a "killscreen" of this who knows? :)
Overall cool job it was different and will mess with your head the first 15-30 minutes.

Very nice, thanks. :)

Hi Danman,
Great to hear that you like it.
In a reply to your impressions.
It is possible to jump when jumpman is at the uppermost girder in the barrels stage. However, it is not possible to jump at jumpman's start position (next to the platform where Pauline stands). This is as designed. Initially I positioned jumpman at the platform where Pauline stands. Although this platform is displayed as a horizontal platform, the game considers it as a tilted girder. The effect was that jumpman couldn't walk this platform: he was gradually submerging into the platform. I tested various solutions to solve this, and the best was to create the gap between Pauline's platform and jumpman's start position. To prevent jumpman from still getting onto Pauline's platform, I had to disable jumping at jumpman's start position. This is implemented the same for the barrels stage, conveyors stage and elevators stage.
This was one of the adjustments I had to make because jumpman was now able to go in places that were not possible in the orginal arcade game. Another example is in the conveyors stage. Jumpman is now able to walk the uppermost conveyor (the one where Donkey Kong stands). It is possible to go down at the right side of the screen and then go up at the left side and enter the uppermost conveyor left of Donkey Kong. It is then possible to climb the two ladders left of Pauline's platform (the ones that Donkey Kong uses at the end of the stage when he picks up Pauline and leaves the stage). This was a problem because jumpman kept climbing also leaving the screen. To prevent this I had to implement a height check and prevent jumpman from climbing any higher (see attached image).
I agree with your impression that the rivets stage messes with you at first. I had the same. It was very counter intuitive to jump the rivet gaps to fill them. I kept walking into the gaps ... with a lost live as a result.

Impressive hack, i cant wait to play it.
-
Really really like this, only thing I'm not so keen on is having to jump to "lay" the rivets rather than just walking across.
-
That's funny

Here's a tailored marquee to complement it.
This one was a no brainer... :D

Great to hear that you like the game. Also like the marquee.
The Donkey Kong Reverse and Donkey Kong Crazy Barrels Edition rom-hacks are now supported by Homebrew Mame (HBMAme) and Libretro FB Neo (lr-fbneo).
I have uplodaded the corresponding roms (dkongrev.zip and dkcbarrels.zip) to the GitHub pages of the rom-hacks.
