about downloading blue burst

There are plenty of homemade servers, but they use a buggy software and many details in the game don't work.
Then you have schthack, it has a more stable software, some stuff may not work but it is only a few, the majority of the players play here so if you want a community to play with i would recomend this one.
There is also the jp pso bb server, it has lot's and lot's of japanese players, this is probably the best free bug server around, but unless you can comunicate with japanese players you will have some trouble, especially because the events for example are all explained on the site in japanese.

schthack has in my opinion a low quality community, but if you find the right ppl you will enjoy the server alot.
