Ozzy, Very informative. I've never seen such a detailed description of how it works! |

That's how most low-level programming works. You want to do something, you send a number to a specific address. Want to check something, you read said address. Some devices call them pokes and peeks (c64 those were the actual commands). |

And on the speccy. I remember hacking speccy games for infinite lives etc, by poking to a specific address that held the number of lives. |

So I decided to just go for it and try my Yoshi's Island cart. It was recognized and copied my saves just fine, and they remain on the cart no problem! I played a few levels and when I got to Touch Fuzzy, Get Dizzy in world 1, when I touched a Fuzzy and everything gets all "drunk", the background just went berserk - waaay more than it should on the real system. Other than that though, it seems to work fine from what I can tell. |
