Hello, Doing lot's of coding for the new MyIDE + 1Mb flash cartridge, made me came up with this file. I have basically packed a number of standard 8k roms into the cartridge. Please note that demon-attack only runs on a 800 based OS. Just play with it and let me know if you like the setup. Kind regards, Sijmen (mr.Atari) |

Just had a look at Demon Attack - the XL issue is down to a direct jump into the OS that appears in 2 places: $B72E & $B986 - original = $D1,$E7 i.e. jump to $E7D1 The equivalent jump in XL is to $C10F. However, I don't think there's a common vector this can be replaced with. Maybe the loader could be adjusted to 'patch' the addresses if the appropriate OS is detected? Here's an updated bin. Regards, Mark |

Hi Mark, Thanks for the file 
I know the problem with this cart. I didn't know were to patch it. THANKS! Info: E7D1 = NMI-entry point of the 400/800 revA-OS. Imagic was very lucky it also runs on a RevB-OS, since Atari moved this entry point to E7AE...... In a XL-OS rev_2 or higher the address would be C0E2, but to be safe you should use the vector at $E45F. This makes a compatible cart for all Atari's! Cheers, Sijmen. |

Hi, I noticed that you are calling the files roms. Quote: I have basically packed a number of standard 8k roms into
the cartridge. Please note that demon-attack only runs on a 800 based OS. Just play with it and let me know if you like the setup. Kind regards, Sijmen (mr.Atari)  I like the setup and was wondering if the programing Language roms could all be added to a cart like this. Assembler Editor Basic xl Basic xe Action Mac/65 Atari Basic rev. C and so forth.  I have tried but I must not be using the correct syntax on the Perl command line..

I used a trick to save these rom-images to the flasher-disk. First I figured out on what sector each 8k bank starts, then I used QMEG to bypass the inserted cartridge and saved this area with the build-in editor to these sectors. The menu is 'first' cartridge on bank #0, which I programmed myself. It's very close how the first MyIDE-loader was build. Now, OSS cartridges are not standard 8K, but 16k (or more) banked. These can not be put in the cartrdige like I did. Cheers, Sijmen. |
