Thank you Vampier, but I hope that I won't have problems while reading and parsing softwaredb.xml since I have already developed a tiny RSS Feed reader in the past, so I think that it shouldn't be too difficult to implement an XML import function in the frontend. I was planning to copy the XML data into a SQLite database, so I can make quick comparison between HASHes of files and what I have stored in the database. Another thing I'm planning to add via database support is a list of favourite files, so anyone will be able to create their very own list of favourite ROMs, Disks and Tapes, and -of course- the support for different machine configurations.
Well... all this things will come, maybe slowly, because I've just started learning how to code in Realbasic (and on Mac OS X)

Let me know if you need a raw SQL dump

cesco, check the text I mentioned here: http://www.msx.org/openMSX-Control-0.2.2.newspost4190.html

(If you want to know how to control openMSX from an external program.)

Thank you Manuel

Ok, I have just finished to develop the SHA1 HASH calculator and the XML parser. Now I need to put all this things together in the frontend...

IMHO a database is a good choice for making quick queries for HASH Codes, and SQLite3 is a good format for a database, since it can be managed very easily by a lot of different languages (Visual Basic, C#, Python, PHP, ASP, ...)
BTW... If anyone is interested in a SQLite3 version of the OpenMSX Software database, I have just create it... here is a link to download it: softwaredb.sqlite.zip

Vampier, sorry for this stupid question... I had a look at your list, but I didn't understand if your list has more entries than softwaredb.xml. Do you have also information about MSX Disks and tapes, that are missing from the XML file? I would really need them...

Third Alpha release is here, and Peashooter is finally becoming a serious frontend ;-)

What’s new in this release:

* You can (finally) select which machine configuration you want to use to run MSX games and applications. Just verify that you have provided the necessary system ROMs to openMSX before using a machine, or the emulator will not load. In case of doubt, just select “Default configuration”. You cannot have different configurations for each game yet, but you can define different configurations for MSX1 ROMs, MSX2 ROMs, MSX2+ ROMs, Disks and Tapes.
* Now the front-end have a built-in database with a list of valid MSX1 and MSX2 files. If your files match the HASH codes of a valid ROM, it will be detected by the frontend that will show you some information such as the title, year of publication and publisher. If available, it will also display a brief description of the game / app.
* You can also alter the description of a game or application just clicking twice on the description box (the little textbox on the lower-right corner).
* Minor improvements and some bug fixed.

Cool!
