I have Amiga Forever 2012. My understanding is this still uses Kickstart 3.1 ROM to boot AmigaOS 3.9 (confirmed by a browse in the "rom" directory), however I have found it rather slow in booting 3.9 under WinUAE.
The included Amiga Walker prototype's Kickstart 3.2 beta ROM also seems to boot 3.9 just fine, as does some recent AROS/68k nightly builds. 3.9 still boots much, much slower than 3.1, or even AROS/68k with Wanderer. If it is possible to rip my own 3.9 ROMs to boot it faster (which I have the licence for), I would be interested in doing this. Last edited by Mequa; 13 February 2012 at 15:32. |

Sending your ROM to be burned by someone to get it back in real form is in no way piracy. I am not going to buy a fucking eprom burner just to use it once.
This kind of mentality is more hindering rather than helpful |

EDIT:- Cant be bothered, already tried calming this down.
Maybe I quoted the wrong person to start with. Last edited by FOL; 13 February 2012 at 17:28. |

Now, which is the exec.library offset we need to modify the value to change the background color? And, could you please explain the method you used to replace the "insert floppy" screen? Again, it would be really cool if we could modify our roms to suit our personal cosmetic tastes |

its part of romboot, not exec
you must know the position of romboot in your rom then you must know the offset inside of your version from your romboot its not absolute ... not a simple c64-style peek/poke-job |

(the insert WB screen I mean). I'm surprised noone has made it easier. To change the background colour... have you determined the original colour values to go looking for? |

Whats the name of the program and how does it work. Btw. we are talking about a romboot with 4,5 kb size showing a 16 color hires-nonlace animation. I used code that "paints" every part of the screen, it´s no raw-style data inside. http://www.youtube.com/watch_popup?v=DQ2A9-ZUCP4 http://www.youtube.com/watch_popup?v=SzxxXAQYxow |

of the same size, then replacing only the non-copyright part that you provide with the program, then saving the result array to a new KS file. "Every KS I've looked at" is an important qualifier here, which doesn't include anything other than the hand holding blue disk screen, so I don't know if anything is done differently since then. You are saying the screen is drawn programatically so you can't see the image data? That would be a change since the original screen. Up until then (at least), simply ignore the file type an load KS into a program that views the file as a bitmap with variable alignment and variable (bits per pixel) property, and play from there. All intuition graphics (fonts, window borders, default pointer, gadgets etc.) are clearly visible, and so are the "Amiga", "Workbench", "V1.2/3" bitmaps. I do know that the original A1000 bootstrap is tight, and they had to make it tricky. The "Amiga" bitmap is still visible in that one though. I did have a play, but simply not motivated. I would do it to a real Amiga, but for UAE, I would prefer the original screen. |

V1.x is with graphics, thats true.
If you know "Twinkick" for the A1000 .. I changed "V1.3" to "Twinkick V1.3" on the bootscreen. Since V1.4 (pre2.0) the bootscreen is coded. All elements are drawn, checkmark (or boingball), diskdrive and disk. The copyright-text is taken from exec-string. |

So that's not going to be much fun for the user producing different graphics
Still, such a program with set options sounds easy since the grunt work is done. I did one to patch firmware files for Garmin handheld GPS units where their interface provides no option for custom intro screens/wallpapers, but that was 8-16 bit bitmaps... from there, I checked the image the user provided was of the expected dimensions, bit depth, etc. Like I said though, in the case of an emulator, a program pretending to be an Amiga, I think it's contrary to customise the emulated Amiga that way. I took a quick look at 3.1, and can see only some things clear.. intuition and fonts look the same. I see a hammer head.. don't know what that's for? If you have a real Amiga, I think a patch program would def be a winner. |

Thinking of it, I don't know if there'd be trouble for giving away the boing ball?
and then this: at the time I thought, a ROM patcher that did that would be well received on the particular forum, but I'm not sure you get to extend the length of the original "Amiga" bitmap to say something else. (and the longer wrist is stupid anyway. I don't think a Sony PSP program will be any good for Amiga land: http://www.freewebs.com/defxev/Legend.htm but extended it to PC. It can view in monochrome, 8 bit (with some random palette), 16bit (RGB565), and 24 bit. but I think the Amiga (bitplanes you might call them) layers are between 1 and 8 bit where 1 pixel is worth 4 bits or so. It needs a tweak for that in the case of "Amiga", "Workbench", or "V1.3" text, etc. The actual blue disk might still be RLE or something. Last edited by xArtx; 24 July 2013 at 13:07. |

Yah, and that might be the case (concerning any distribution) even if you made it yourself.
Well if I ever win the millions, I'll buy the whole thing and give it back. |

Thats the problem of nearly every boingbag#3/4 module.
The only legal way is a patchfile for the existing romboot. I still had no time to execute "scompare" to create a "spatch"-file :-P Last edited by Ratte; 24 July 2013 at 22:10. |
