In this tutorial series you will learn how to make a simple single-player Pong-like game for the Sega Mega Drive using SGDK! If you just want to see the full source code, you can get it from Github.

Megapong BONUS - Flashing!

Posted October 21, 2019

Alright, we have a complete and working game now. We have graphics, gameplay, scores, game overs…sound is still missing, true, but that’s a topic for another tutorial. However, we can still add something to make our game a bit better: The almighty Juice.

In order to juice things up as it were, we’re going to make the ball flash when it’s hit by the paddle. It’s a small effect, but an important one when it comes to retrogaming. Hitting Robotnik wouldn’t be as satisfying if he didn’t flash, after all. So let’s do this!

    HaxeFlixel Tutorials!

    If you’ve popped over to the tutorial section recently you might have noticed that I’ve added my very first HaxeFlixel tutorial! It shows how to implement a simple, pixel-perfect 2D water shader which I used for Go! Go! PogoGirl. But a few of you might be wondering what a HaxeFlixel is. Well, it’s a 2D game framework that is as powerful as it is underrated! It runs on the (also underrated) Haxe language, is extremely well documented, open source, and has built-in functions for almost anything you’d need.

    Streets of Was

    As I’m sure many of you will remember, the original Streets of Rage for the Mega Drive had multiple endings. The real canonical ending has you beat the crap out of Mr. X, thereby ending his reign of terror forever (yeah, right). However, if you confronted Mr. X with a buddy in tow, a new possible path unlocked. A quick refresher is in order. When you confront Mr. X he will ask you to join his organization.

    Streets of Rage 2 Design Docs

    A few years ago, Yuzo Koshiro posted a pile of old game design documents for Bare Knuckle 2 aka Streets of Rage 2 on the Ancient blog to commemorate the release of Streets of Rage 2 3D on the Nintendo 3DS. These documents gave a deep insight into the game’s inner workings, technical aspects, designs and even some cut content. They were an awesome resource for one of the most awesome games ever created.
