Mathy Posted July 22, 2011 Share Posted July 22, 2011 Hello Sebastian Because I don't have the hardware to transfer software from my Apple to my Atari at the moment. Hmm, might try the emulator later today. BTW why don't you split up the software in a "hardware specific part" and "the rest". That way you'd only need to rewrite part of the software if you find bugs or add features and you could have different "device drivers" for different hardware. Check out my (AT)ASPI page. sincerely Mathy Quote Link to comment Share on other sites More sharing options...
candle Posted July 22, 2011 Author Share Posted July 22, 2011 i don't split, i combine Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted July 22, 2011 Share Posted July 22, 2011 What Mathy's suggesting is already almost a reality. IDE Plus and SIDE already share the same low-level API, and if all new IDE interfaces adopt the same SIO command set and XDCB (as well as the same partition table design), all the tools written for one interface will work with another, the only differences being in the driver / BIOS.

candle Posted July 22, 2011 Author Share Posted July 22, 2011 loader needs to be self-contained, besides, there is a quite good standard established quite some time ago i like to follow - its called ATA Quote Link to comment Share on other sites More sharing options...
Mathy Posted July 22, 2011 Share Posted July 22, 2011 Hello Candle But (AT)ASPI could become the Atari standard. sincerely Mathy Quote Link to comment Share on other sites More sharing options...

a8isa1 Posted July 23, 2011 Share Posted July 23, 2011 small improvements, one bug found and corrected i could really use some feedback For this version of fat32-intmyide.xex I get a black screen when I try to load any programs. For the previous version the only problems I had discovered are kikstart - doesn't load pitfall - data corruption on player character -Steve Sheppard Quote Link to comment Share on other sites More sharing options...

candle Posted July 23, 2011 Author Share Posted July 23, 2011 eh, i wanted to speed up build process and used conditional compilation... too bad that i did that wrong again, two other versions fat32-intmyide.xex fat32-myide.xex Quote Link to comment Share on other sites More sharing options...
a8isa1 Posted July 23, 2011 Share Posted July 23, 2011 Steve, could You attach files you're reffering to? Sure. Here they are. BTW, I'm still not able use fat32 with an MBR and FAT32 partition I generate from OpenSuse linux CF is in "floppy mode" (is that the name?), i.e. there's no MBR. Fat32 can see the files. With the previous version could load them. trouble_games.zip Quote Link to comment Share on other sites More sharing options...

Rybags Posted July 24, 2011 Share Posted July 24, 2011 anything that loads inside 0700-0c31 will fail other than that - should work Suggestion - when I wrote a B-Loader ~ 20 years ago, I tried to get it to use as little memory as possible for the needed loader part. Once the program is selected for load, most of the program is no longer needed. I put some of the loader code within the RAM normally used for IOCBs. Leave IOCB #0 alone, that leaves $350-$3E7 where you can have some code (printer buffer another thing you can overwrite). You could also use the bottom part of the stack. I suppose the biggest hurdle faced by modern loaders is that if you're supporting 256/512 byte sectors, that puts a big dent in available RAM.

Roydea6 Posted July 24, 2011 Share Posted July 24, 2011 some loader improovements anything that loads inside 0700-0c31 will fail other than that - should work i won't post another version for quite some time now - lots of little things to do i don't have the Side Cart yet but the two Myide versions work ok. Is there a cold start keypress for exiting and starting a new game without cycling the on/off switch. Also about formating the CF card is there an optimal cluster size.. I only had problems with a couple games (probably not xl/xe version) or loader inside 0700 etc... This was all done on real hardware. 130 XE External MyIDE Cart with Atarimax version of SDX444.rom and 1200 Internal Myide with external SDX444 SicCart both with SIO2SD floppy set as Drive one so I could load your program. Thanks! Quote Link to comment Share on other sites More sharing options...
candle Posted July 24, 2011 Author Share Posted July 24, 2011 cluster size is not important in future version the bigger the better, but not right now i've managed to get below 0c00, so some more programs shoudl load here it is fat32-side.xex fat32-intmyide.xex fat32-myide.xex Quote Link to comment Share on other sites More sharing options...
a8isa1 Posted July 24, 2011 Share Posted July 24, 2011 (edited) Before I went to bed last night I noticed that your fat32 loader works with Altirra while emulating 400/ 800. Does this mean it might work with a real 800? (off topic: Will SIDE work in a real 800?) The 800 hasn't been my primary A8 for a long time now but I've always wanted something to keep it on stand-by, that is to say, having a game loader with mass storage available. I've had a barebones SDrive for it for a couple of years now but something in the form of a cartridge (perhaps even a right-side cartridge) is really what I've been dreaming, for a long, long time. I'm seeing a glimmer of hope now! -Steve Sheppard Edited July 24, 2011 by a8isa1 Quote Link to comment Share on other sites More sharing options...
candle Posted July 24, 2011 Author Share Posted July 24, 2011 SIDE will work with 400/800 with 48k of RAM one thing though - you can't close cartridge door when SIDE is in I could do special board for it, but unfortunatly i don't have any enclosure for it (one i can buy new) if that doesn't change i can't do much about it here are last improovements every of my troublesome xex files are loading now properly i've also added clearing memory routines which had helped some games to work properly fat32-intmyide.xex fat32-myide.xex fat32-side.xex 1 Quote Link to comment Share on other sites More sharing options...

flashjazzcat Posted July 24, 2011 Share Posted July 24, 2011 I just tried two partitioned CF cards (both with FAT32 partitions as the first entry in MBR; one partitioned with MS Diskpart, the other with Linux Parted), and neither works with the loader (latest SIDE version). "Stock" CF card, however (i.e. one with a floppy boot record on sector 0), works fine. Quote Link to comment Share on other sites More sharing options...
zaxon Posted July 24, 2011 Share Posted July 24, 2011 From 2 days sorting and checking games, so far 156 have proven without major problems. Sorted in directories, Quote Link to comment Share on other sites More sharing options...
a8isa1 Posted July 24, 2011 Share Posted July 24, 2011 OK, I'm the guy who always asks for extra features (and for free)... I was just wondering would it be possible to keep MyIDE working as normal but have a special version of fat32-intmyide.xex access a slave device? That's assuming one owns a dual IDE/CF adapter. Mind you, I don't own a dual IDE/CF adapter at this time. I am just asking if it would be possible. -Steve Sheppard Quote Link to comment Share on other sites More sharing options...
candle Posted July 24, 2011 Author Share Posted July 24, 2011 it would be possible, but is it really desirable? not much to do in code, but really what for? i would rather focus on getting directories sorted, adding proportional font, and getting history of cursor movement (so cursor would not return to 1st entry in directory after cd up), etc Quote Link to comment Share on other sites More sharing options...
