Specifically, Atari800 patches the operating -system ROM to support high-speed emulated disk I/O. Unfortunately, -when this is done, OS++'s checksum routines correctly detect that the -ROM checksum doesn't match, and the OS doesn't start. - -The *correct* way to fix this is to make Atari800's ROM patch actually -update the stored checksum after patching. For Atari800 2.1.0 and -previous, the workaround is to replace OS++'s checksum calls with NOPs, -which is what's been done to this copy of OS++ (future versions of -Atari800 will hopefully have proper support for OS++) - -Note that OS++ only works correctly with Atari800 if the emulator's -high-speed SIO patch is enabled. Without the fast SIO patch, OS++ can't -read the emulated disk drives. Most likely, this is due to Atari800 not -emulating the hardware 100% perfectly. - -Also, this is documented elsewhere, but worth a mention here, too: OS++ -does not include BASIC! Machine language programs normally don't call -the BASIC cartridge, so they will be unaffected. If you want to be able -to run BASIC without using the copyrighted Atari BASIC ROM, try the -excellent public domain Turbo BASIC XL. |
