You can check them all, in the official RULES thread, here: http://karoshi.auic.es/index.php?topic=2277.0

Open participation with self-mantaining entries, new games and RAM size limits, drastic changes into the jury and prize sections... be sure to check them out, and just join the MSXdev'12 *now*!

I know someone that's waiting for a new version of WAVer :p

Hahaha! That's true.

There are plenty of versions of WAVeR around, but none of them are complete. Blame on me! 

there's just one waver feature I'd like, and then it'd be all lovely and kittens and roses.

(as mentioned in my post in the english section) having some kind of loadingscreen, even if it's just a tiny bitmap image or some text, just so it looks like a nicely packaged game (for tape/cd etc) instead of a screen full of WAVER LOADING A GAME [gamehere] WAVER sort of thing.

It's always been an important rule since the 1st edition and I don't think it will change : a digital version is a way to promote both the contest and an eventual release on cartridge that can be enhanced with additionnal levels for example.

 People who want a contest with a game only available on cartridge for maximum 1 year can enter the #msxdev compo (another contest) at the beginnning of 2013 for example with at the same time the game on cartridge, and the digital release will only happen in the beginning of 2014.

For games only on cartridges for more than 1 year, the only way is the release outside a contest. However, is this realistic when the number of real machines' users decreases ? Maybe selling digital versions should be viewed as a solution (for a price that should be lower than the cartridge version).

Actually, the rule has never been understood in this way and for example Karoshi Corporation and Relevo Videogames have released most of their MSXdev' games in enhanced version on cartridge, while the non-enhanced version remains online.

So, there's no any real problem. From this point, the coders choose the way they prefer for their games and the end-user buys or not the cartridge, that's indeeed another discusssion when you come to games only available on cartridges for 1 year, 2 years, 3 years .... or the eternity.
