I'm pretty sure it would be illegal to upload them with the roms included. Plus, the emulator isn't quite fit for public consumption yet (i.e. saved games still aren't being saved to appvars and there's no tool to build an app from a rom yet).
As for illegality, I would have to say that it probably would be. As for saving to appvar's, I would have to know how you are doing that, but if there is a command that allocates memory, or something, you could use that, just have the emulator see that the save commands are saved to the appvar.
You would have to list how to get a rom, when you release the emulator.
Good luck, and I would love to test and help. |

| How did you emulate the hardware stuff like the screen? (assuming you still have low-level compatibility) |

the gameboy uses a memory-mapped dispay (i think >.>)
each frame, he scales the buffer and copies it to the screen (probably 110/4=28 fps) |

| I think it's illegal to list where/how you get a rom. Search engines are best for this kind of thing |

Actually, it has memory-mapped tilemaps and sprites.  |

*bump*
Okay, I've run into a serious problem which involves the TI-OS. When I delete an APP and the emulator is moved in the defragmentation, AN ENTIRE APP PAGE WILL BECOME BLANK (filled with $ff). Just so you know, this happens every time with Link's Awakening and it's happened once with Super Mario Land 2 (but I've only tried it once), and both of these APPs are 34 pages large. Could some TI-OS guru help me out here? This is a very bad problem... |

34 pages????? :D
You mean a page from the emulator, or from the games? |

| Personally, I would suggest creating your own delete routine, and doing with it, what you need. For example, backing whatever you want to stay in an appvar or something, and then, you wouldn't have to worry about it getting deleted. |

| You can't do a such thing unless you're a hook guru. (able to detect which app is going to be deleted in the Mem menu) |

| Unless (MenuCurrent+2) is set in mem mgmnt I don't see a way (and even then it is difficult). |

| Why can't he just go in, and reset each page to $FF? |

@calc84maniac:
I don't have any specific ideas yet - the defragmenting code is buried pretty deep, it'll take me a little while to untangle it - but just in case it helps: precisely how large is the app? (You said it's 34 pages; how large is the last page?) Also, which page gets erased? A random page? The same one every time? One that's zero mod 4? |

The last page is empty except for the signature. Also, the same page gets erased every time for the same ROM, but it differs between them. In Link's Awakening, page $11 gets erased. In Super Mario Land, it was a different one (either $07 or $17, I can't remember which). |

| If I remember correctly, the TI-OS can only "delete" one sector (64k or 4 pages) at a time, so if an App shares a sector with another one, it could be problematic. |
