Cassette game loading

Post by Fungus »

I've been experimenting with old games on tape, and I wish to transfer them to disk. But something about how the files load from tape keep them
from executing from disk... I'm stumped as there is no code in the cassette buffer... anyone have info on protected vic20 tapes?

Any help mucho appeciated

I think that is the old memory trick. I use it all the time. You'll have to alter the memory pointers so that the computer thinks the program is longer than it is. The extra memory is where all of the additional info is stored. For example:

| game code ||graphics|

When I make a game, the program itself is only in the first part. The graphics are in the second part. After loading it to tape, the graphic part is "forgotten" when the pointers are repositioned to the end of game code. When you save it to disk, you'll only get the first part.

A good example is blue meanies.
