The project planner webpage can read a set of dependent activities with their time length (in days). Click "Generate plan", and the application calculates the project calendar and a Gantt diagram using ASCII charachters.

To better understand how the planner works, just look at the example and play a bit with it.]]> http://andrear.altervista.org/home/index.php?entry=entry081107-194746 An AWK script for the Dijkstra's Algorithm.

It's an AWK script to find the shortest path on a graph, represented in a textual form. Don't know who might need it, hope it helps anyway.]]> http://andrear.altervista.org/home/index.php?entry=entry081023-175929 crt0.o file available in the tutorial had the wrong origin address (0x8000 instead of the correct one, 0x4000). The original source crt0msx.s was correct.

I recompiled crt0msx.s and replaced the crt0.o file, so the tutorial should now run straight. By the way, the command line I used to compile the ".s" file is:

as-z80 -o crt0.o crt0msx.s

Hope it helps :)]]> http://andrear.altervista.org/home/index.php?entry=entry080920-220620
Nice, but build the AST node + build the grammar + build the lexer + build the treewalker + adjust the makefile + read docs definitely *isn't* an immediate task. Hope to upload here soon my small example project, bye.]]> http://andrear.altervista.org/home/index.php?entry=entry080726-125046
Integrating Eclipse and the SDCC Z80 cross compiler would be a nice experiment; if I try, of course you'll be kept informed :)]]> http://andrear.altervista.org/home/index.php?entry=entry080627-181658 http://andrear.altervista.org/home/index.php?entry=entry080606-211021
They now restored their power systems, but I can't refrain from saying the silly thing:

I know that the flex/bison tools aim to mantain a wide compatibility range, but I wouldn't have bet that bison parsers could work on sdcc; but surprise, I now have my small parser in an MSX ROM file...



Together with the ROM, I want to share with you the sources and a small HOWTO describing the procedure I followed; in the MSX Software section on the right, look for the Bison Grammar on MSX entry.

(by the way, bison output ran rather straightforward on sdcc, but I could not get the same results (not yet :) with the flex tool)]]> http://andrear.altervista.org/home/index.php?entry=entry080504-194816 MSX Software section you'll find a new version of iMsx, the game launcher created by our friend Aci.



Main changes are in the game search/filter procedure, and only involve the main executable, so you don't really need to reinstall this new version, you may just replace the old iMsx.exe file with the new one.

Hope you enjoy Aci's efforts and have fun with his product, my best regards to you all!

1) some small errors fixed in img2spr, latest version is now 1.2
2) some errors fixed in MSX Sprite Editor 16x16, latest version is now 3.1]]> http://andrear.altervista.org/home/index.php?entry=entry080330-193731
Please check the "MSX Software" section menu on the right, I also changed the screenshot example, should be explicative enough.]]> http://andrear.altervista.org/home/index.php?entry=entry080329-213226 icon: it's the img2spr utility.

Draw a 16x16x24bit image using whatever program you wish, then convert it to our familiar 32-byte sprite pattern format; sprite is now ready to be included in your game source.

The utility is small and rough: that was enough for me, but it might be of help to you developers, so why not to share it? Hope you enjoy!]]> http://andrear.altervista.org/home/index.php?entry=entry080325-094923 http://andrear.altervista.org/home/index.php?entry=entry080323-123839


It's a pretty simple fractal, and it was the ideal candidate to convert it to 3D; after some simple adjusting, here's the final results:



If you have 3D red/blue glasses and want to take a 3D look, please follow the related link below (it's also available under the "PC Software" menu.]]> http://andrear.altervista.org/home/index.php?entry=entry080314-121142
About MSX: recently I tried the Karoshi's Caruso PSG Tracker, that's an interesting tool for MSX developers, have a look if you never did.

Bye, Andrea.]]>
