From my experience with BasicBuilder, the compression ratio is close to 2:1, meaning that it can pack 30,000 bytes into a 16,354 byte application. If you are packaging mostly pictures, the ratio will probably be greater, while packaging mostly programs will yield a lower ratio.

I must warn you though, packaging more than three programs into an app with BasicBuilder seems to dramatically decrease the speed of execution. A fix to this problem is to re-organize the main code so that the sub programs can be inserted into the main code. This task will be more difficult for less experienced programmers since their code is most likely less organized than an experienced programmer.

Also for some reasons it doesn't seems to work well with xLIB real(1,2,3 commands, not to mention it requires you to rename all your Recallpic 1,2,3 to Recallpic A,B,C or something like that, so it's a PITA to convert some BASIC games to it. I tried with Mana Force, Illusiat 8 and Metroid II so far. Mana Force never went further than the menu, Illusiat 8 never ran and gave me an ERR:INVALID error

lol gonna take  a while especially since there's a limit per day I think to raise reputation
