[ATARI] Altirra 2.0.1 Test XVI

Hawkmoon - bardzo ładna grafika, niestety grywalność taka sobie

Altirra 2.1 test 16 [March 9, 2012]:

????

Altirra 2.1 test 15 [March 8, 2012]:

Bugs Fixed:

• IDE: Fixed banking in KMK/JZ V1 mode and added 3K ROM support. 
• POKEY: Fixed asynchronous receive mode not resetting timers 3+4 that are already running.

Altirra 2.1 test 14 [February 27, 2012]:

features added

• Debugger: Added .basic_dumpline command.

Bugs Fixed:

• Disk: Fixed handling of XF551 high-speed sector skew format commands ($A1/$A2).
• Disk: Fixed error return for unsupported Write PERCOM Block requests.

Altirra 2.1 test 13 [February 21, 2012]:

features added

• BASIC programs can now be booted.
• Fast boot option now accelerates timeouts for powered down disk drives.
• Disk: Accurate disk timing prediction is now preserved when burst I/O transfers are enabled.
• Display: Added CIO intercept based enhanced text mode.

Bugs Fixed:

• Display: Added CIO intercept based enhanced text mode.

Author's Comment:

• This version has support for loading BASIC files, but note that it still goes through the boot process and therefore enabling Fast Boot is recommended. It also contains improvements to disk timing prediction so that more protected disks will boot in SIO patched or burst I/O mode, and a new CIO-based enhanced text mode that allows for text screens up to 255x255 and traditional command-line editing.

Altirra 2.1 test 12 [January 27, 2012]:

Bugs Fixed:

• Disk: Fixed inverted write protect bit status.
• Disk: Attempted writes to a write protected disk now return errors instead of a NAK.
• Disk: Fixed command response when accessing a drive with no disk.

Author's Comment:

• Fixes several disk drive issues, tunes the drive sounds a bit, and fixes the Dimension X regression.
• XEGS game ROM banking should be fixed now.
  
• DOS XE issue should be fixed now (was a problem with XF551 high speed I/O).
  
• Dimension X issue was due to a display list timing issue related to a jump instruction fix -- both cases should work now.
  
• CPU emulation speed should be cycle exact or very close to exact, certainly not off by an order of magnitude. The rule for performance is: anything done in a loop in BASIC is going to be dog slow, no exceptions. BASIC is itself an interpreter, and on top of that Atari BASIC is not a particularly fast one. The only way to get good performance for vertical sprite movement is to move the sprite data in assembly language, which means either calling an ML routine directly or aliasing the sprites on top of string buffers so you can move the sprites with Atari BASIC string commands.

Altirra 2.1 test 10 [January 27, 2012]:

Features Added:

• Disk: Added rotation and seek sound emulation.

Bugs Fixed:

• Disk: Fixed forced sector ordering (.diskorder) for .pro images.
• Disk: Step delays were not always reflected correctly in command delay time (only rotational position).
• Display: Fixed display mode matching when /f is specified on the command line.
• CPU: Fixed cycle behavior of ASL/LSR/ROL/ROR abs,X instructions in 65C02 mode.

Altirra Version 2.00 test IX [January 6, 2012]:

features added

• Debugger: Added heat map support.
• Display: Text can now be copied out of ANTIC modes 2, 3, 6, and 7 (GR.0, 1, and 2).

bugs fixed

• Disk: Adjusted step rate of 810 drive to 5.3ms.
• Input: Improved Caps Lock key support.
• Cartridge: An error is now thrown when attempting to save a cartridge image in .CAR format with an unsupported mapper.

Altirra Version 2.00 test VII [January 2, 2012]:

features added

• Display: Added scanline display mode.
• Display: Added integer-multiple version of preserve aspect ratio sizing mode.

bugs fixed

• Disk: Format command now sends back ACK+ERROR+buffer instead of NAK on a read-only disk.
• Input: Fixed bug in keyboard repeat detection code.

Altirra Version 2.00 test VI [December 31, 2011]:

• Switching to RAW keys would seem to solve the keyboard lag problem, but it also totally kills the auto-repeat on the cursor keys for some reason, so that solution is not really usable for me. ()
  

Figured it out -- turns out "repeat count" means something completely non-intuitive in the WM_KEYDOWN message, so Altirra wasn't detecting key repeat on the host side properly. This version should work better:

Altirra Version 2.00 test V[December 30, 2011]:

bugs fixed

• Fixed startup crash on Sandy Bridge CPUs on Windows XP.

Altirra Version 2.00 test IV [December 29, 2011]:

bugs fixed

• Disk: Fixed handling of XF551 high-speed sector skew format command ($A1).

Altirra Version 2.00 test III [December 28, 2011]:

features added

• Covox emulation support.

bugs fixed

• Increased paste keyboard timer to reduce dropped keys on line processing delays.
• Simulator: Inhibit FP math acceleration hooks when PBI ROM overlay is active.
• Debugger: "read" and "write" terms can now appear more than twice in a conditional breakpoint expression.
• POKEY: Fixed glitching in high-pass filtering.

Author's Comment:

• This version adds Covox support and also fixes a bug that was causing noise in high pass filtering (affected Nemesis demo). I did also do some heavy reorganization on the CPU hooking code, so watch out for SIO/CIO patch breakage.
• I'll have to look into the DOS XE issue. It may be another problem with PERCOM block support (grr).

Altirra Version 2.00 test II [December 25, 2011]:

features added

• SlightSID emulation support.
• Disk: Added support for format skewed ($66) command.
• Disk: Format commands ($21, $22) now support high-speed operation.
• Disk: Added emulation profile modes for various disk drives.
• Disk: Reduced ACK-to-complete delay when accurate sector timing is off.
• Debugger: Added .sum (sum memory area) command.
• Debugger: Added .warmstart command.
• Debugger: Added ap (alias pattern) command for adding aliases with patterns.
• Debugger: Added additional aliases to a8 command (set Atari800-compatible command aliases).
• Debugger: Added alternate L>addr syntax for setting an address range length based on an end address.
• Serial: 1030 Modem support.
