Inspired by the likes of DahrkDaiz, ATA and other great rom hackers of the mid-2000s, Frantik started work on Super Mario Unlimited with the hopes of creating his own asm-heavy Mario masterpiece. It took close to 7 years, but eventually the game was released to the world in late 2011. Overall, The hack was well received and was even featured in a video by James Rolfe of AVGN fame. Despite the popularity, it was a little rough around the edges, most notably with some questionable choices near the end and a little too much of that infamous “Nintendo Hard”.

In 2017 Frantik decided to go back and start adding a bit more polish, and Super Mario Unlimited: Deluxe was born. Everything good about the original has been made better, and everything bad has been removed or at least cleaned up. This is the original vision he had when he first began 15 years ago!

I registered here just to make a review, it was that good

Reviewed By: thesoftbulletin on 18 Mar 2021

I’ve played my fair share of SMB1 rom hacks, most of which are frankly abysmal. I know folks rave about the excellent rom hacks for SMB3, but I honestly feel like this hack rivals some of the best SMB3 hacks out there (and considering the source material being worked with, making as high of quality hack as this for SMB1 as compared to SMB3 is like comparing someone being forced to start a fire with sticks vs. someone having matches, so I’m blown away by how great this game looks and sounds).

Much of the complaints I’m seeing here remark on the difficulty curve, and I can’t say those are totally wrong (one review specifically notes the bump in difficulty beginning in World 6, likely because they found the 4, 5, 6 warp zone and went straight there). After having warped to World 6 myself, I can agree the difficulty is far more challenging than World 3.

That being said, THIS GAME FEELS FAIR AND PLAYS FAIRLY. I feel like that’s the most important distinction to make. Some games are frustrating in that you feel ripped off. This game is challenging, but the controls are tight and hitboxes are where you think they should be, so it doesn’t hurt to lose. Plus, with infinite lives and a death counter, it’s a fact that you’ll die, a lot. But in my experience, you try a few things and you find something that works, and you move on, getting a legitimate satisfaction that comes from well executed game design.

Really a triumph by frantik with his hack. Threw it on my Everdrive and have been playing it for hours. A+
