0.5 (2009-08-06)
|
|
|
|
- Fixed signatures of getc/putc callbacks in monitor that were broken
|
|
when the ObservableMemory interface changed in 0.3. Closes #1.
|
|
|
|
- Fixed that ROL would not properly set the Z flag. Closes #2.
|
|
|
|
0.4 (2009-06-06)
|
|
|
|
- Added ez_setup.py to bootstrap setuptools installation.
|
|
|
|
0.3 (2009-06-03)
|
|
|
|
- Added shortcuts for monitor commands such as "m" for "memory". These
|
|
are mostly the same as the VICE monitor shortcuts.
|
|
|
|
- The terminal width can now be changed in the monitor using the new
|
|
"width" command. Some commands, like "mem", will wrap to this width.
|
|
|
|
- Fixed a bug where BRK would increment PC by 3 instead of 2. Thanks
|
|
to Oscar Lindberg.
|
|
|
|
- Added a new 65C02 MPU simulation started by Oscar Lindberg. It is
|
|
now mostly complete.
|
|
|
|
- Added a new "mpu" command to the monitor. It will switch between the
|
|
NMOS 6502 and CMOS 65C02 simulations.
|
|
|
|
- A new "devices" module has been added to organize device simulations.
|
|
|
|
- The mpu6502 and mpu65c02 devices have been reorganized internally to
|
|
use Python decorators to build their lookup tables based on an
|
|
idea by Oscar Lindberg.
|
|
|
|
- A new "utils" module has been added with various utility functions.
|
|
|
|
- The ObservableMemory interface has been changed for clarity.
|
|
|
|
- Python 2.4 or later is now required.
|
|
|
|
0.2 (2008-11-09)
|
|
|
|
- Added a new "disassemble" command to the monitor. It can disassemble
|
|
any range of memory ("disassemble c000:c010"). If labels have been
|
|
defined, the disassembly will show them in the operands.
|
|
|
|
- Added a new "assemble" command to the monitor. It can assemble a
|
|
single instruction at an address ("assemble c000 jsr $ffd2").
|
|
Labels in the operands are also supported ("assemble c000 jsr charout").
|
|
|
|
- Moved the character I/O area from $E000 to $F000 for compatibility with
|
|
the EhBASIC binary saved from Michal Kowalski's Windows-based simulator.
|
|
In a future version of Py65, the I/O area will be configurable.
|
|
|
|
- When running a program in the monitor, a read to $F004 will now do a
|
|
non-blocking read from STDIN. If no character is available, a null
|
|
byte ($00) will be returned.
|
|
|
|
- Fixed a bug where a CMP instruction could crash the simulator due to
|
|
an undefined variable.
|
|
|
|
- EhBASIC 2.09 now runs in the simulator!
|
|
|
|
- Documented all remaining monitor commands. In the monitor, use the
|
|
command "help command" for help on any command.
|
|
|
|
0.1 (2008-11-21)
|
|
|
|
- First release.
