carmel_andrews Posted August 23, 2012 Share Posted August 23, 2012 (edited) Phaeron, do you have the link to drac o/s, since i recall your emu supports 65816 mode and i wouldn't mind having a looksie at this o/s I presume you mean this.. http://drac030.krap....os-15082008.arc For Arcs I use http://www.izarc.org/download.html Thankyou fellow londoner, I am guessing that Powerarchiver or 7zip/winrar (do have winzip but can't be arsed to install it) work with .arc files Edited August 23, 2012 by carmel_andrews Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted August 23, 2012 Share Posted August 23, 2012 (edited) Don't have power archiver myself but Winrar does NOT work.. BUT, Phaeron has just mentioned you can use the disk explorer in Altirra to open the arc and then drop it onto the PC and then onto altirra or in the case of the rom, use it as the otheros.

flashjazzcat Posted August 23, 2012 Share Posted August 23, 2012 Altirra can mount ARC files in its Disk Explorer, from which you can just drag out the files. I put this in because I was tired of having to boot into SDX in order to extract files off an ARC on a disk image and then reboot into another DOS to get the files off that into H:. Nice touch - I didn't know about that. I've got Stuffit Expander installed because I need to handle a lot of Mac stuff, but I'll have to try the ARC mounting in the emulator.

Fox-1 / mnx Posted August 23, 2012 Share Posted August 23, 2012 Power-Archiver, WinZIP, WinRAR and 7-ZIP all don't support ARC, ALF, ZOO and LZH (anymore). That's the reason I still use PKXARC, ZOO and LHARC, ran from DOS command line. Good to know Altirra can deal with ARC files... Quote Link to comment Share on other sites More sharing options...
atari8warez Posted August 23, 2012 Share Posted August 23, 2012 (edited) I also use IZArc, it is a GUI based archive utility which supports a variety of formats including ARC. There are a few add-ons the installation program wants you to add (for support purposes) so don't rush through the install process and make sure you uncheck those optional add-ons that you don't want. The installation also offers a free Game to play (I guess it's online gaming). http://www.izarc.org/ Edited August 23, 2012 by atari8warez Quote Link to comment Share on other sites More sharing options...

Mclaneinc Posted August 24, 2012 Share Posted August 24, 2012 Latest beta from Phaeron Copied from the blog.. http://www.virtualdub.org/beta/Altirra-2.20-test3.zip Portable mode fix, fix for some ROM images getting mixed up in the new UI, a couple of fixes for DOS 2 disks in the Disk Explorer, and partial save state file support. Be warned that the save state support is still not stable, though -- it doesn't do enough checks, so you can cause the emulator to malfunction or crash if you load save states into the wrong version or with radically different configurations. Currently it only checks whether the kernel ROM matches. 1 Quote Link to comment Share on other sites More sharing options...
Shannon Posted August 24, 2012 Share Posted August 24, 2012 Altirra didn't have savestates? I never realized that! Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted August 24, 2012 Share Posted August 24, 2012 Superb. I asked about save-states a while back but I didn't expect the matter to receive attention so quickly. Thanks! Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted August 24, 2012 Share Posted August 24, 2012 (edited) Save states have been in Altirra for ages but only as mem saves which you lost when turning off, now its good old save to disk and replay any time. Just remember what Phaeron says in the blog post re making sure you use the same setup you saved from or you could get problems. If you played it off one particular crack then best to make sure its the same one when returning. Oh, Breaker on the forum was eagle eyed and spotted that the load and save requester dialogues both say load save state at the top.

xxl Posted August 25, 2012 Share Posted August 25, 2012 maybe it's not that important. 1bit music on GTIA or PIA is rather silent but if you try this on SKCTL (bit7 $D20F) then music is very clear and LOUD. try this on atari press RECORD & PAUSE on XC12... temp.obx Quote Link to comment Share on other sites More sharing options...
fox Posted August 29, 2012 Share Posted August 29, 2012 Does your Atari actually have a battery backed up RAM disk? Shift+F5 is cold reset in Altirra, so it's supposed to simulate what you get when powering up an Atari after leaving it off for a while. This includes all RAM data going bye-bye. I think Alex/Bit Busters had a battery backed up RAM disk in his Atari. Some people have an additional Cold Reset button. I was able to recover source code from the RAM disk after my Atari crashed, by quickly turning it off and on. It rebooted and just a few bits flipped in the RAM disk, which were easy to fix manually.

+JAC! Posted August 29, 2012 Share Posted August 29, 2012 Regarding coldstart and RAM Disk: Many OS ROMs (QMEG, etc) have a built in way of performing a cold start. I hardly every turn a computer off for a cold start. Hence the question if a cold start should keep the RAM disk in not really related to having batteries or not.

fox Posted August 29, 2012 Share Posted August 29, 2012 I disagree with you JAC! If your OS ROM has a way to perform a cold start, just use it within Altirra. What we discuss here, is how Altirra's command for the cold start should work. Quote Link to comment Share on other sites More sharing options...
Bunsen Posted August 29, 2012 Share Posted August 29, 2012 I don't want to confuse. The ABBUC Award IS NOT the ABBUC Software Contest. An ABBUC jury judged Altirra 2.00 as the best pc programm in 2011. 5 Quote Link to comment Share on other sites More sharing options...
phaeron Posted August 30, 2012 Share Posted August 30, 2012 An award from ABBUC? Wow, I'm honored. Regarding the reset with RAM preservation, I can put in a "lukewarm" reset which does a cold reset without clearing all RAM. A minimal amount of RAM needs to be hit though because at least PUPBT1-3 need to be hit for the XL/XE OS to actually do a cold reset. I'm thinking that changing $0000-03FF would do the trick and be vaguely like what might happen on real hardware. Quote Link to comment Share on other sites More sharing options...

phaeron Posted August 31, 2012 Share Posted August 31, 2012 save states? coolio... finally no need for Atari800win anymore... You can say that when they fully work. Did anybody managed a working paddle emulation under Altirra? (I've tried to configure a CX77, but even the normal mouse to paddle configuration doesn't change the according registers?!) Should work fine -- just tested it again with Kaboom!. Just keep in mind, if you're writing your own code, that you can't cheat: you've got to hit POTGO and if you're on slow pot scan mode you need init mode off.

eegad Posted September 1, 2012 Share Posted September 1, 2012 Save state files finally? EXCELLENT!!! Can't wait for the next final release version of Altirra with this feature! It's the one reason I've been hanging onto AtariWinPlus. It really comes in handy with longer, multi-level games that didn't have a save feature. And it's also great to use with Alternate Reality because you can just load the state rather than have to go thru all the file loading / disk swapping when continuing the game.

phaeron Posted September 2, 2012 Share Posted September 2, 2012 This version has a bunch of fixes to save states: http://www.virtualdub.org/beta/Altirra-2.20-test4.zip http://www.virtualdub.org/beta/Altirra-2.20-test4-src.zip For those wondering why I put off save states this long, they're actually tricky to do. It's not as simple as just dumping all internal state because (a) there are elements that can't be saved and have to be synced, and (b) that produces a save format that is unvalidated and can blow up the emulator if anything is wrong. Part of what I've been doing is rewriting the save code so the save state file has a chunk-based format with architectural state separated from internal state and adding validation. There are also other issues, such as what happens to modified disks and cart images when you use save states. Generally you don't want persistent storage included in save states -- sucks if your save games get rewound when you load a save state -- but with a DOS failing to roll back the disks can result in filesystem corruption. A bit of warning: currently Altirra does not restore any disk state, including bound images. This means that states will not work if saved in the middle of a disk load. I need to figure out how to handle restoring the disk image mappings. 10 PRINT PADDLE(0),PADDLE(1):GOTO 10 In "Mouse -> Paddle A" mode the first value goes from 1 to 227 (the full range should be 0-228, BTW: setting of range would be a nice addition, needed for CX77). With the setup depicted below, I only get '228' for both channels... I checked the history on the paddle range, and it turns out I narrowed this because of an issue with 5200 Vanguard blowing up with 228. I need to check that again, but in the meantime I've opened the 800 paddle/tablet ranges to 0-228 as there's no reason to tie that to the 5200 joystick behavior. The tablet isn't working for you because button 4, the stylus up/down input, isn't bound. This means that the stylus is always up and thus no stylus input is received. It's a bug in current versions that the stylus is always up in this case; I've fixed it in 2.20 test-4 so that the stylus defaults to down. Reset Windows Layout - WTF.. what a brutal clean and useful, thanks for it i lost my screen window today, but i found this thing Yeah, I put that in after people were getting stuck with broken window setups. Never figured out how people kept losing the display, but View > Display brings it back if you've accidentally closed it. Protip: If you really manage to hose the configuration settings, the /resetall switch will blow everything away. Quote Link to comment Share on other sites More sharing options...
