Galakong: A Donkey Kong/Galaga shoot 'em up hack

[10yard]

Hi, I'm not sure if this is the right area for my post. Please let me know if it needs to be moved.



I've been working on Donkey Kong rom hacks for a couple of years. My latest hack is "Galakong". It's a hack of the original Donkey Kong to add a Galaga ship which can assist Jumpman by taking out barrels, fireballs, firefoxes, pies and springs. I added explosion effects, Galaga sounds, a scrolling starfield background and end of level shooting stats.




Here's a recent gameplay video. I managed to rack up a crazy 254,000 points on the first 4 levels.

I'm pleased with how it turned out




The default mode is single player, with your ship following Jumpman's position. Jumpman can control the ship independently when he is on a ladder. The jump button also shoots. There's also a 2 player co-op mode where a 2nd player controls the ship using separate controls.

If you'd like to try it out you can get it from my github at:

Cheers folks

Yes, i'm finding it fun to play. I'm sure it won't be everyone's cup of tea.

Yeh say hi , people always appreciate that and will help us to learn a bit more about you.

Will you be releasing the rom data for people ? And for mame ?

Dave.

This hack uses MAME/LUA plugin system to add extra features. Simply drop the galakong folder into your MAME plugins folder. It will run with the original Donkey Kong rom (not provided) by adding -plugin galakong to arguments i.e.

mame -plugin galakong dkong

I made a Donkey Kong arcade frontend for my DIY arcade machine which makes it easy to install my hacks and all the other rom hacks that have been developed by the community. It will automatically do all the patching for you. I'll post some info about that on another thread.

Haha, so true, it took an age to get it all working as I wanted. I'm sure I got rid of all the bugs.

Clever cross-over that seems to work very well

I have made an update today to make it more beneficial to hit multiple targets with one missile.

1 hit = 200 points

2 hits = 500 points

3 hits = 800 points

4 hits = 1200 points

The 4 hit maximum is new. When achieved, a love heart is displayed and bonus sound is played.

Here's a really short video showing me hit 4 barrels:

Cool! Thanks. The Pi4 release of my frontend is a couple of releases behind but will be updating it next few days. It's only Galakong that would be your difference really for now. It's chock full of other hacks and fun stuff for you to check out in the meantime.

I was able to get my hack working with Donkey Kong Junior. There's more opportunity to leech points but it's more challenging to control the ship when on the vines.
