gferluga Posted October 7, 2023 Share Posted October 7, 2023 I'm trying to convert some Apple II disk images to IIGS format. For instance micro_chess.dsk in 2MG format but with no success. Any idea?

nick3092 Posted October 7, 2023 Share Posted October 7, 2023 Why? Any IIgs (real using a floppy emu type of device or emulated on a pc) should be able to handle DSK images. There is no need to convert to 2mg just because it is a IIgs.

gferluga Posted October 7, 2023 Author Share Posted October 7, 2023 I have a dsk image of Micro Chess that runs on AppleWin or Apple][ and runs on my IIe and IIc on real floppy disk but will not run on GSplus nor mapped on my GS with Fujinet card on SmartPort. The same for Multiplan or any other 160k dsk image. Most of the times the message is: Unable to load Prodos Quote Link to comment https://forums.atariage.com/topic/355501-convert-apple-ii-disks-to-iigs-format/#findComment-5329793 Share on other sites More sharing options...
magnusfalkirk Posted October 7, 2023 Share Posted October 7, 2023 There's your problem right there. Normal Apple II disk images are 140K not 160k. Being 160k the GS won't recognize them as Apple II disks. The easiest way to turn them into 2mg images is to use AppleWin to copy the files from the disk image to a 2mg image. Load up Copy ][+ and make sure the 2mg image is formatted, then copy the files from your 160k image to the 2mg. Don't try doing a disk copy because Copy ][+ will complain about size mismatch, if I remember right. 1 Quote Link to comment https://forums.atariage.com/topic/355501-convert-apple-ii-disks-to-iigs-format/#findComment-5329797 Share on other sites More sharing options...
nick3092 Posted October 7, 2023 Share Posted October 7, 2023 (edited) If you search the 4am collection on Internet Archive for microchess, there is a cleanly cracked version there (it's v2.0 of microchess, not sure if that is the exact one you are looking for) that I'm sure the DSK image will work for you. 4am's releases are more or less the gold standard for Apple II floppy images.

gferluga Posted October 8, 2023 Author Share Posted October 8, 2023 Sorry. 140k I’ll try your suggestions. Thanks in advance. Quote Link to comment https://forums.atariage.com/topic/355501-convert-apple-ii-disks-to-iigs-format/#findComment-5330019 Share on other sites More sharing options...
masteries Posted October 8, 2023 Share Posted October 8, 2023 (edited) Try via Total Replay 5 .hdv or via Total Replay II: Instant Replay (at least Battle Chess is included there), these work well on the Apple ][gs Edited October 8, 2023 by masteries 1 Quote Link to comment https://forums.atariage.com/topic/355501-convert-apple-ii-disks-to-iigs-format/#findComment-5330039 Share on other sites More sharing options...
351cougar Posted October 17, 2023 Share Posted October 17, 2023 I didnt see anyone mention ciderpress for working with disk images. I have had problems with disk images and emulators occasionally . applewin being the all but GS emulator does 51/4 in #6 as 140K and 2mg but only on #7. Gsplus kegs and activeGS do 800K on #5 140K on #6 and hd images or somewhat larger disk images on #7. I have issues with 1.4 mb floppys in #5 and dont behave like floppys in #7. The applewin emu seems to get a lot of updates but there doesnt seem to be a lot of love for the GS for some reason.

You had to have a special drive interface card and a SuperDrive/FDHD to use 1.4mb floppies. A stock IIgs should handle 140k floppies in slot 6, and 800k floppies and smartport hard drives in slot 5 using the built in drive interface (IWM). I can't speak to any IIgs emulators on how they are configured with any optional interface cards for handling other drive types, as I rarely use emulators, especially IIgs emulators.
