Oricutron

Debugging

To access Oricutron's debugger you need to press the F2 key. This will show you this screen:

In the monitor, number arguments are decimal by default, or prefixed with $ for hex or % for binary. Pretty much everything is output in hex.

In most places where you can enter a number or address, you can pass a CPU or VIA register. (VIA registers are prefixed with V, e.g. VDDRA). Anywhere you can pass an address, you can also use a symbol.

Commands

To use Oricutron's debugger, you need to know some keys:

  • F2: Return to the emulator
  • F3: Toggle console/debug output/memwatch
  • F4: Toggle VIA/AY information
  • F9: Reset cycle count
  • F10: Step over code
  • F11: Step over code without tracing into subroutines.
  • F12: Skip instruction

Version 1.2 (01-Nov-2014)
  • Fixed memory access breakpoints which were broken in (at least) v1.1.
  • Added snapshot files to the filetype autodetection
  • Added a virtual on-screen keyboard, and the ability to remap keys (torguet)
  • Fixed autobooting of Jasmin disks (christian)
  • ACIA 6551 serial port emulation, including a virtual modem which lets you connect over TCP/IP (iss)
  • Fixed a bug in the V flag emulation for SBC/ADC (christian)
  • Detects invalid .tap images (encoded length larger than tape image length)
  • Added copy to clipboard (iss)
Version 1.1 (07-Dec-2013)
  • Now possible to set scanline and fullscreen options when built without OpenGL support

  • Disk and tape image autodetection. Oricutron will now attempt to detect the configuration required for any disk or tape inserted via commandline or menu.
  • 'Insert disk 0/1' menu items enabled even when no disk drive is enabled. Inserting a disk will use the autodetection routines to determine which drive type to enable.
  • Autorun for Jasmin and Pravetz disks
  • Fixed crash bug when switching between software and GL rendering on builds using SDL requesters.
  • Various AY emulation improvements
  • Simplified system timing
