Super Mario Kart - Epic Racers

Hack of Super Mario Kart


Super Mario Kart - Epic Racers has come a long way. This ambitious project began all the way back in 2003. Starting as a direct follow-up to The Impala Battles, this mod was dubbed The Impala Courses. Later that changed to Epic Battle, and finally the name became Super Mario Kart - Epic Racers.

This mod was intended to be some sort of tribute to the Stifu Board forum. Therefore you’ll encounter members from back then. And no, Jesus himself wasn’t a member of our board, but he was a nice opposite to the dark Loki. ;-)

Work on Epic Racers started in a time when only small parts of the SMK ROM were documented. There were no other mods, and only one, very limited, editor. Step by step the complete ROM was documented. Using Lunar Compress, graphics could be extracted and changed.

Stifu started working on the graphics, while Ok Impala! painstakingly worked on changing the track designs. Initially it proved to be too complex to change the A.I., so tracks were created with the old A.I. The results were far from ideal. With the help of smkdan, Stifu started working on a new track designer to fix all the issues with track design once and for all. Epic Edit saw the light of day and was shared with the world. Meanwhile work on Epic Racers slowed down, due to life changes. In 2016 it seemed like the project was dead.

Fast forward to 2020. Ok Impala! decides to start from scratch on the track design, ditching all the ballast of the old track designs. Stifu got on board again to work on the last graphical changes. In several months, revamped tracks and graphics were created, while a lot of bugs and A.I. problems were ironed out.

So, there you have it. 17 years later, Epic Racers is finally, proudly, presented to the world. Hopefully you’ll enjoy all the work and love that went into this mod!

Romhacking Excellence.

Reviewed By: M.Walrus on 08 Nov 2020

I recently got done playing through all the GP tracks on Hard difficulty and made a video for it, and wrote a bit of a review with accompanying thoughts on the game.

All GP playthrough video:

New tracks, new racers and new graphics make this a standout in the Mario Kart modding scene. 17 years in the making, this romhack was just released a couple days ago and after practicing the stages a bit I decided to make a video playthrough for all the new GP tracks.

The new tracks are, for the most part, very good. Some of the early tracks have a couple unusual gimmicks that will take a bit of trial and error to figure out for new players, but are a welcome variation from the vanilla track styles. The Epic cup at the end is the most polished of the bunch, and also features the fewest gimmicks as well. Many of these tracks feel like they are polished enough to be in a proper SNES Mario Kart sequel.

Battle Mode also has 4 new tracks, and all characters have been replaced with new graphics. GP mode also has scoring changes so that you don’t always need to finish in the top 4 to progress, though you can still restart via the pause menu if you want, at any time.

Items also have a different coat of paint, though I feel there was a bit of a missed opportunity to nerf Camy’s CPU ability. Just like Princess’ Mushroom in the regular game, she just tosses it right in front of you many times, and it will make you drop to the bottom of the pack no matter what you do, requiring some miracle to get back into the lead afterwards. This makes playing as Stifu on hard mode a pain in the butt, because she will always be in second place spamming pills unless some freak accident happens to her, like the kart getting stuck or a proper knockout that causes her to finish further down the pack. Because of this, I only used Stifu on the Sapphire cup, and stuck to Sasori for the rest. Loki/Jesus’ invincibility can be troublesome, just like Luigi/Mario in the original, but is far more manageable than being shrunk/flattened and the penalty that comes with it. These elements are in the original game, so it’s not a knock against the romhack really, just one of the more frustrating parts of the playthrough I had.

You can toggle a rearview mirror by pressing the X button, but I recommend not doing this, as the framerate will often tank because of all the sprites on the screen. MiSTer’s SNES core ‘CPU Turbo’ option may help with this, but I have not tried it yet. Some enemies that throw items in front of you, will also trigger the rearview camera to come up momentarily, and this is also a problem at times because not only will they be spamming things in your path, but they can also make the controls inconsistent and throw you off, because of the varying framerate at times. This was probably the worst issue I noticed while playing this romhack, but it is infrequent so not a huge deal.

Overall an excellent effort by Stifu, OK Impala! and smkDan. Congratulations to the team for getting it over the finish line after such a long development time, and the exemplary quality of this first release!
