**CLOSED** KLDC 2020 - Rules and Submissions

Link Thread Closed

Welcome to KLDC 2020! My name is Doctor No, and I'm a staff member for Romhack Races - a community and Twitch channel that hosts regular races of kaizo levels and hacks. I am honored to be the host for KLDC, and I'm looking forward to having the best seat in the house to the creative stuff you all throw our way!

For this edition of KLDC, SMWCentral and Romhack Races are joining forces to make this contest as big as possible. Kaizo has seen a lot of growth, both in popularity and in creativity, since the last KLDC, and we want to give the community the strongest platform to flex and showcase your creative skills in making kaizo levels. We are hoping for this to be one of, if not the biggest contests SMWCentral has ever put on, and you are invited to crack open Map16 and give us your best kaizo level.


Make and share with us a brand new, Kaizo:Light level.

You must use worldpeace's Instant Retry patch, but all other customization is allowed.

The deadline for entries is 17:59:59 UTC Monday, February 24.

Required Patch

For the sake of consistency, as well as the sanity of our judges, we are asking all entries to use Worldpeace's Instant Retry and Multiple Midways patch with infinite lives enabled.

Retry System (+ multiple checkpoints) v2.06a

Above and beyond the above patch, all custom graphics, sprites, music, and any additional patches (including SA-1) are fair game!

Be aware if any patches (such as SA-1) affect emulator and/or console compatibility and include that info in your submission. There will not be a collab planned for this competition, in part to allow creators to use whatever they desire in creating their level.

Optional Baseroms

If you don't want to deal with picking and choosing things to add to your level, Romhack Races has a baserom that all of our weekly kaizo race levels are built on. Disclaimer: The RHR baserom does not have SA-1 enabled.

Romhack Races Baserom

worldpeace has also created an updated version of the 2017 KLDC baserom to be compatible with recent updates and tools.

How To Submit

You must submit your entry as an unlocked .bps (NO .ips PATCHES!) file, created in FLIPS off of a clean copy of SMW.

Upload it to your personal File Bin on the site (click on Files in the SMWC site menu), then link to the file in this thread. If you edit your level, edit your original post - double posts will get deleted. You can put your .bps file in a .zip or 7-zip archive if you want.

You can talk about your level in this subforum and in the contest channels on SMWCentral and Romhack Races Discord servers, but in order for it to count, it needs to be linked here in this thread. Please create a new thread in this subforum for discussion and feedback about your specific level, and join in general discussions in the discussion thread.

To help ensure judging is as fair as possible, please do not include your name within your level design. Judges will not be provided creator names when entries are given. While we can't promise they won't find out, we want to make it as fair as possible.

The deadline for entry is Monday, February 24 at 17:59:59 UTC. All links must be live and pointing to the correct file by this time.

Contest Rules

  • Do not submit a level that has been included in any past races, compilations, or accepted/pending/rejected hack submissions to SMW Central.
  • You can work with a partner, but an individual is limited to one entry. You can't enter both a level on your own and one with a partner.
  • Glitches are permissible, provided it is clear to the player what the intended strategy is and the glitch is reliably executable without savestates.
  • No more than two exits. If you have a second exit, it also must be beatable without savestating.
  • Unless you feel it’s absolutely necessary, don’t use more than 6 sublevels.
  • Levels must be compatible with either bsnes or SNES9x.


  • Posting a ROM as part of your submission
  • Posting an .ips patch instead of a .bps patch
  • Posting a corrupt patch file
  • Submitting a level that is not compatible with bsnes or SNEX9x.
  • Submitting a level that does not conform to the Kaizo: Light difficulty level
  • Not using the required patch and/or not enabling infinite lives
  • Including content within the level that violates the rules of SMWCentral


The judges for this year's contest are:
  • GlitchCat7
  • LinkdeadX2
  • white_moth
  • Katerpie
  • Strizer86

Judges will use the following 100-point scale and criteria:

Level Design (60)
Was playing the level an enjoyable experience expected from a kaizo: light level?
Is there a consistent difficulty curve to progressing through the level?

Level Creativity (20)
Did the creator bring something new to the table?
Does the level add something to existing kaizo elements?

Aesthetics (10)
Does the level have any visual or audio errors that detract from the gameplay?

Kaizo Elements (10)
Is the level demanding of the player in the style that kaizo levels are intended to be?
Does the player have a fair chance to beat the level without the use of savestates?
BeeKaay has written a fantastic explanation on the concept if you're confused.
Total - 100 points

Each judge will do their evaluations separately and confidentially - judges who livestream their evaluation playthroughs will not confer on scores nor reveal their scoring until results are announced.

Once all judges complete their evaluations on all levels, results will be compiled and tabulated. Each level's top score and low score will be thrown out and final results determined by the average of the scores remaining.


The top 3 levels will be recognized with a special trophy, as well as a choice of games from the SMW Central games list. If more than 75 entries are received, a trophy for the rest of the top 10 levels will be awarded.

Top levels and level creators will be featured on stream for Romhack Races. This may include: level races, interviews, judge conversations and other types of content.

All participants outside of the top 3/10 will be awarded a participation trophy.

Please feel free to ask questions in the Discussion thread, as well as in Discord on either the SMWC or Romhack Races servers - both have dedicated KLDC channels that you can use to share works in progress and discuss levels.

Let's see what the kaizo community can do with the gloves off. Show us what you got!
I'm not a doctor.

You can use older versions of worldpeace's Multiple Midways patch (such as the one in the 2017 KLDC baserom) - the only reason the version is listed in the link is because it is in the name of the patch itself.

1/14/20: Added link to worldpeace's updated 2017 KLDC baserom.

I hope I win!

Hope it's fun!

Good luck everyone!

Good luck everyone!

EDIT: Made a small change. Link updated.
The second level I have ever made. It is based on rock climbing, where you have to always trust your belay partner to prevent you from falling to your death. I am just starting to make levels, so it will be nice to get some helpful feedback.
