Anyone can participate and it is free to enter. Software submitted to MSXdev will be treated as freeware; free to download and free to play software. The games for this competition are in ROM format and can be used in any MSX emulator.

You can read all about the jury’s verdict right here, it includes a full report downloadable as .pdf.
MSXdev21 runs from January 1st 2021 until August 31st 2021.
- Start: January 1st, 2021
- Deadline to submit your entry: August 31st, 2021
- Jury deliberation: September 1st, 2021
- Deadline for jury reports: September 30th, 2021
- Final results made public: October, 2021
The rules of this year’s edition are simple; all software is MSX1 compatible. That means it should run on any MSX machine with a limit of 16KB of RAM and without any hardware extensions. In MSXDEV context, it is known as the “classic” category.
All the games should be 100% compatible with this MSX configuration, which is defined as follows:
- CPU: Zilog Z80 running at 3.58 Mhz
- VDP: TMS9918/TMS9928 or compatible video processor
- PSG: AY-3-8910 or compatible sound chip
- Cassette interface: 1200/2400 baud
- RAM: 16 KB (non memory-mapped)
- VRAM: 16 KB
In addition, it is allowed to make use of additional MSX hardware but they will not be taken into account when determining the final quality of the game by the voters. The goal of the contest is producing fine quality games that could be fully enjoyed in any MSX system. Extra hardware is just not allowed this year, just to keep it simple.
The selected format for the games is an MSX ROM file. Cartridges have been the most successful media format for first generation MSX computers, and a substantial part of the best games ever produced on that platform were published in this format. Nowadays, this format is also interesting because it can be easily loaded into real MSX computers, using a flash cartridge, a ROM loader or a ROM converter. Besides, it can also be used directly on emulators.
And as there exists a growing phenomenon in the MSX scene of people developing physical MSX game cartridges, the MSXdev organization aims to encourage this game format.
Regarding the ROM size, any size will be accepted.
These ROM files can be developed using any programming language. There are no requirements here, but of course Assembly is strongly recommended. Other compiled and/or interpreted languages are perfectly admissible. MSX-BASIC can be used as well, providing the final product is converted into a MSX ROM.
All submitted games will be tested and evaluated to the prerequisites outlined above. And they should work perfectly on any MSX compliant machine. If a game does not run properly on all MSX computers with 16 KB of RAM, it could be disqualified by the organization.
Although original games will be preferred, non-original concept games will be also accepted. This includes conversions from arcade titles and/or other console or computer systems, as well as adaptations of already existent games. However, recompiled games or hacked games will not be accepted. Finally, direct graphic or music rips from other authors used without permission are out of the question as well.
In case of doubt, the organization is entitled to ask for proof, such as the source code of the entry. Any suspicious game can be disqualified if the organization decides so. It should be noted that only complete games will be accepted; beta-versions, demos or “to be finished” games will not be included in the contest.
No previously released games will be accepted as entries to the contest. We mean, game sold in the past, being sold now or even available for download somewhere. All entries must be unreleased games until they enter in the contest.
Besides this, all entries must be accompanied with the required game instructions written in English. Other artwork can be added to the package, although it will not be taken into account when voting.
Members of the jury panel cannot take part in the contest with game entries.
This edition’s jurors are:
|Cas Cremers (Parallax)||Gameplay|
|Richard Cornelisse (huey)||Graphics|
|Hans Cnossen (Kid Cnoz)||Sound|
|Bart van Velzen (norakomi)||Polish|
|Tony Cruise (Electric Adventures)||Originality|
Every submitted game gets rated by the expert-jury for a minimal of 5, and a maximum of 100 points in total. In case of a tie, the jury will appoint one extra point to one of the games as a tie-breaker. Every juror will write a (short) argument on their scoring.
Both scored points, and the written jurors statements will be included in the final jury report. This report will be available for download at the compo’s closing time.
