Re: gtBASIC
Every resource in gtBASIC is statically allocated, (almost), this means it's allocated just once as part of the compile and then load process, there is no cleanup you should be doing when resetting your app, apart from resetting your app's state and variables.

Re: gtBASIC
In gtBASIC you can do full screen double buffering pretty easily, but there are some major caveats, the main one being you lose another 19k or so of RAM; but probably more importantly you chop up 32k of contiguous RAM, (in the extra 32k page page), into the same segmented fashion as the first 32k pa...

Re: gtBASIC
Looks pretty awesome. write a custom line routine for the vines, (very simple one that saves background pixels and then restores them).
I was going to do Pitfall as my next project, but I'll move onto River Raid.
