| Sticky Revision: |
minor tweaks, everything tested now works
Remove all traces of older attempt to embed perl into CPU emulation module and move forward to just using it via XS bindings
- transfer debug state into C, added accesor M6502->debug(); - update_*_R functions to keep perl vars in sync with C - tests
begin refactoring into proper XS module (really need to do this so I can handle SDL event loop)
beginning of keyboard controller (added ports for start)
cleanup and refresh memory map on load image
and in the same spirit, render memory map super-fast using SDL (and in the process, make it white :-)
experimental video renderer
other minor tweaks: j ff89 works for the first time!
Use current $a for m if no arguments
dump_R now returs registar dump and cli uses it to dump registers state
don't confess, but just warn of write access to read-only memory
debug and trace shouldn't be remembered
j 1000 now sets next command to r 1
more cli improvements: - load checks for file and returns success - prompt now returns original line
fix number of lines that e cli command displays
another refactoring: extract preferences to Prefs class
tweaks
- remove unused M6502::ram (can access @mem directly :-), - debug messages now include name of module - better last command handling
- trace and debug are off during init phase (to speed up things)
hexdump directly access @mem
added _write_chunk which fills in memory and refresh vram if needed
update vram display from prompt
- use M6502::run_for to Exec6502 with run_for cycles - added primitive command-line callback (cli)
better output mostly
various tweaks to make it work somewhat
- implemented push_R to push register changes back to perl - don't trace while rendering memory map - render just video ram without show_mem - use Exec6502 to execute limited number of cycles
more tweaks
tests now pass
somewhat works now...
Orao now calls M6502->init correctly, and other tweak to make it semi-working
comming along nicely: implement parts of memory maps
startup, open window
make screen open
great source reorganization, M6502 are now more-or-less generic 6502 CPU bindings, while all specific stuff to Orao (which isn't working yet) is implemented in Screen (SDL display) or Orao (palform specific code)
