KMinesweeper: Minesweeper for kindle - Page 3

I give it a try.

We have some games here (mostly wriiten in C) like xMahjong, Kondike and others. But all this games are Kual extensions. To use them you need to understand and install Kual first and the the game extension.

I would love to see more games and applications that you can install and organize as simple as a book.

That was the reason for my question. There should be a lot of simple Java GPL games in the internet that could be converted into Kindle eBook games if the changes are not that big.

But if you needed to rewrite most of the code that this makes only scene if the developer is personally interested in the game / application.

It was my first kindlet, probably there is some simpler way to port a java swing app.
Most of the code i wrote was to optimize the repaint of the screen only when necessary and only on the portion of the screen that has changes.
If you can accept to repaint the whole screen frequently, the porting is simpler.

However, remember that e-ink displays are slow, so only "static" games/app (like board games) can be easily ported

Another thing is that kindle's jvm has a smaller api set compared to the JREs used from many of the GPL apps you can find internet

You might want to look-up (search: gmplay and his nickname) how geekmaster did streaming video on the Kindles.

That is:
The newer combination of e-ink screen, hardware controller, and firmware is not as slow as you might think.

Note:
I am pretty sure he did not use the Java API, but the results should be informative.

My PW1 (FW 5.6.1) reports an error.

There is the log file content:
