lemiel Posted July 5, 2012 Share Posted July 5, 2012 I am not sure about emulating tapes, but maybe you can add possibility of support of tapes/cas files with non standard blocks? http://blanty.net/atari/BombFusion.zip is cas which is stopping to read after 40 blocks - start of non standard blocks. Wave is loaded, but file is 92 times bigger... ( http://blanty.net/atari/BombFusion.7z ) More about this format here (PL only): http://www.atari.org.pl/forum/viewtopic.php?id=9087 And what about support of "real" turbo formats - is it possible?

atx4us Posted July 18, 2012 Share Posted July 18, 2012 phaeron, Are you planning to implement an input record and playback feature in Altirra sometime in the near future, please? It would make an excellent tool for game walkthroughs and/or High Score Club games playback. Compatibility with the MESS input file format would be a plus. Thanks.

phaeron Posted July 19, 2012 Author Share Posted July 19, 2012 The BombFusion tape has A8CAS FSK extension blocks which Altirra doesn't support yet... I can support those, but haven't gotten around to doing so yet. Input recording is touchy as it requires precise synchronization in order to replay properly, so I'd have to think carefully about how to do that. The issue that comes to mind with trying to read the MESS format is that the timing for the input transitions may not be defined precisely enough for other emulators to use it. Probably the most stable form of specification would be to define all inputs as changing at the beginning of vertical blank and having them recorded as such, but then we're getting into when each particular emulator issues input changes into their emulations.

flashjazzcat Posted July 19, 2012 Share Posted July 19, 2012 If you've got VBXE enabled, I think you need to turn on "Interlace" on the System->Video menu for the videos to have the correct AR. 1 Quote Link to comment Share on other sites More sharing options...
Vaughan Posted July 20, 2012 Share Posted July 20, 2012 Guys, Altirra see's my gamepad OK, but only one button. For games like Defender it would be nice to map the spacebar to another button - is this possible? Quote Link to comment Share on other sites More sharing options...

I can support those, but haven't gotten around to doing so yet. When you do fix this Avery, could you ensure that the sound for this particular game is completely disabled (and impossible to enable) in the emulator?

phaeron Posted July 21, 2012 Author Share Posted July 21, 2012 Guys, Altirra see's my gamepad OK, but only one button. For games like Defender it would be nice to map the spacebar to another button - is this possible? Do you see more than one button in Control Panel? You should be able to map spacebar to button 1 or any other button on the gamepad. You need to create a new input map that also has the "console" controller in order to do this. Once that is added, you can map its Space Bar input to one of the gamepad buttons. When you do fix this Avery, could you ensure that the sound for this particular game is completely disabled (and impossible to enable) in the emulator? The emulator can only objectively execute code and cannot make subjective assessments of the sound. Quote Link to comment Share on other sites More sharing options...
snicklin Posted July 21, 2012 Share Posted July 21, 2012 The emulator can only objectively execute code and cannot make subjective assessments of the sound. It's simple, a good old hardcoded routine of: If(MD5(CurrentTapeFile)==MD5(Bombfusion)) { disableSoundUntilNewGameLoaded(); } Something like that'll do! :) Quote Link to comment Share on other sites More sharing options...

I didn't know about the "Controller" step - but after that it was a breeze. Thanks a lot! Quote Link to comment Share on other sites More sharing options...

flashjazzcat Posted August 13, 2012 Share Posted August 13, 2012 Couple of questions / requests: 1. How does one use the BX command in the debugger? 2. Is it possible to specify break on access for a memory range? I'm trying to pinpoint rogue code which is corrupting the program area - it would be a whole lot easier if I could just mark a whole memory region as "break on write". 3. Is there any hope that state files might become a reality? This would be a real boon for collaborative development (i.e. when MrFish deftly breaks the GUI, it would be nice if he could send me a state file to study).

phaeron Posted August 13, 2012 Author Share Posted August 13, 2012 1. How does one use the BX command in the debugger? It causes a break into the debugger when the condition that you specify is true. Example: bx "pc=ciov and x=$10". What it does under the hood is attach an additional conditional expression onto a PC or memory access breakpoint. Thus, you can't do an omnipresent breakpoint like x=4 that would force the condition to be checked every cycle. In current versions the bx command can do anything that the bp and ba commands can do. Note that the debugger has built-in help for all commands, i.e. .help bx. 2. Is it possible to specify break on access for a memory range? I'm trying to pinpoint rogue code which is corrupting the program area - it would be a whole lot easier if I could just mark a whole memory region as "break on write". Yes, there are two ways to do this. One is a length argument on the break-on-access command (ba 1000 L400) and the other is a pair of comparisons in a breakpoint expression (bx "write>=$1000 and write<$2000 and pc < $c000). In the latter case, the expression has to be structured such that the debugger can fish the range conditionals out of the expression. Recent versions also allow additional address checks, i.e. bx "write>=$d400 and write<=$d4ff and write!=wsync". 3. Is there any hope that state files might become a reality? This would be a real boon for collaborative development (i.e. when MrFish deftly breaks the GUI, it would be nice if he could send me a state file to study). Some day is all I can guarantee.

cwscws Posted September 2, 2012 Share Posted September 2, 2012 It would be cool to be able to remap not only joysticks but also the Atari keyboard itself! There is no option to remap e.g. the start, option and select keys to other keys than the function keys. Moreover there is still no sync to screen option. Emulation would be a little bit faster or slower but fluid scrolling would excuse that behavior... Quote Link to comment Share on other sites More sharing options...
cwscws Posted September 7, 2012 Share Posted September 7, 2012 The new test version with remapping function is just great - but I really want to remap start, option and select, too... Quote Link to comment Share on other sites More sharing options...
cwscws Posted September 8, 2012 Share Posted September 8, 2012 By the way: What I would like to see is remapping Atari keyboard keys, not adding shortcuts for certain commands. So that I can remap e.g. Start to the letter A or Select to Tab, etc. Quote Link to comment Share on other sites More sharing options...
