Jury deliberationJanuary 1st 2022 *1 / October 1st 2022October 31th 2022
Final results made public November 2022
*1, the jury may start evaluation any game from the moment it is submitted. However, as the author is allowed to submit updates before the deadline, the final evaluation starts on October 1st 2022.


As this year’s MSXdev edition is open for anything, the rules are simple; anything goes. As long as the game runs on an MSX machine. This can mean any MSX is possible. Be it MSX1 with just 16K or RAM or an MSX turbo R with 2MB of RAM and OPL4, it doesn’t matter. In MSXDEV context, it is called the Free Style category. A panel of expert jurors will judge the entry on gameplay, originality, creativity, polishment and overall look-n-feel.

No one likes strict rules, we don’t either. But we have to have some kind of frame work to accept game entries. If there’s a rule, it would be in the lines of “you MUST have fun participating”. But, really, the only prerequisite is that the game must run on an MSX platform. So, we don’t expect Amiga games here. For the rest, just use your common sense and play fair.

Here are some things to consider:

  • Games and content are original. They have never been published before on MSX, and are not copyrighted by anyone else than the creator. Clones and remakes of existing games are accepted.
  • After submitting an entry, it cannot be published outside MSXdev during the run of the contest.
  • The submitted entry is accepted as the full featured final versions. Updates during the contest are only accepted before the deadline.
  • The game is an MSX game and considered freeware (during the compo)
  • Hardware extensions are allowed
  • The game is submitted as a ROM, or a DSK file. There’s no limit on the size of it
  • Include clear instructions for the gameplay and expected hardware by means of a manual, at least in English. Games get rated on the whole package
  • The game entry can be played by one any, either on real MSX hardware or on emulated. If the game needs extra ordinary hardware to run, remember that this might prevent users (and the jury) to enjoy your creation. Take that as just an advice

The games will be tested and evaluated using the configuration specs given by the author before registration. The games should work on an MSX compliant machine. If it does, it is accepted for MSXdev. In any case, the MSXdev organization has the right to reject or redraw an (already accepted) game entry at any time before the official enrollment-deadline.

The selected format for the games is either an MSX ROM file, or an MSX DSK file. As long as the format is MSX compatible. Any ROM size will be accepted, as will any number of MSX formatted DISK files.


Members of the jury panel cannot take part in the contest with game entries.

The jury team consists of the following persons:

Micha Mulder (NL)Gameplay
Tadahiro Nitta (JP)Sound
Toni Gálvez (SP)Graphics


The rating of MSXdev entries is done by a juror panel of MSX experts. There is a maximum of 100 points per entry to be dealt out. The higher the score, the better. There is no public rating available for MSXdev22.

The panel will rate each game on its quality and provides a written motivation of the rating. The score list will be made public and the winner is announced when all games have been judged by the panel. Furthermore, the jurors scoring and motivations will be publically available as a .PDF file download from the official MSXdev website.


Every entry will be judged on different aspects of the game by the jury panel. Each game-aspect is assigned to one expert-juror. A juror will score two (2) points per game. One on the assigned game-aspect and one on the overall impression of the game. These are separate points to score. A score can be 1-100 points. The total score of a game is the average of all scores (6) from the panel.

The game aspects that are rated separately are:

  • Gameplay
  • Graphics
  • Sound

With a panel of three (3) members, each giving two (2) scores, a game entry is scored 6 times. Each score type is weighted equally. Whereas 1 point is the lowest score, and 100 point the highest, with a minimum of 6 points per game. A judge can only rate using whole integer numbers, so without fractional parts (e.g. half points).

Ties will not be accepted. To prevent those, we instated the resolution of 1-100. The chance of equal scores is lower than previous MSXdev editions that used a lower score resolution.

Nevertheless, in case of a tie (when multiple entries have an equal amount of scored points), the jury panel is required to vote for the better game. The game with the most votes wins and gets 1/10 extra points awarded. If that leads to another tie, the jurors are again asked to vote. This process continues until there are no more ties.

An eventual tie breaking process is transparently mentioned in the final jury report.


In the end, there are four (4) ranking categories published, namely:

  1. Best overall game (average of all scores combined)
  2. Best gameplay
  3. Best graphics
  4. Best sound

From these ranking lists, only prizes are available for ranking list 1 (Best overall game). The other ranking lists are for pride and honor.

Remember, your entry gets rated on quality. And that includes external means like packaging and the manual as well. In order to have your creation judged completely, we advise to include means to access every area of the entry. Like cheat-codes, passwords, screenshots, emu save-states, in-game BGM player, easy/hard level selection and other things you can think of to make it easy for judges to score your entry. We will be discrete with this information, it is for the jury-panel’s eyes only.
