How to create .d88 disk-images?
Posted: Thu Feb 08, 2024 7:25 pm

I`m playing around with SC-3000 emulation right now using the emulator from mr. Tanaka at http://takeda-toshiya.my.coocan.jp/common/index.html
I would like to create a disk image in format.d88 but don`t know how to do this. I found a little tool called "d88 edit" at https://moochos.nobody.jp/en/software/d88edit/index.html but it does`nt seem to create the expected disk images. Is there a known way to create .d88 images? |

The .d88 disk image is meant voor NEC PC 8801 computers and
no way related to Sega SC-3000 (had no disk only tape afaik) Google translation of quasi88-0.6.4/document/FORMAT.TXT in quasi88-0.6.4.tgz -- describes D88 format : The format of the disk image file used with QUASI88 is Disk image file used by P88SR.EXE (PC8801mk-2SR emulator) Conforms to the format. This format is commonly called "D88 format" or "D88 format". It is common to add the extension .D88 or .d88. This format has been personally researched by the author. Even if you make a mistake, please email the author of P88SR.EXE (PC8801mk-2SR emulator) with any questions. Please do not send. |

They had disk, the 3" one also used for the Amstrad CPC series. However I don't think the disk image format supported on most emulators (WinAPE, RetroVM machine) is the d88 one.... |

Well, the emulator mentioned in my first post supports d.88 format, that´s why I asked how to build images. | |

Most of the SC-3000/SF-7000 disk images are in raw sf7 format
consisiting of 40 tracks 1 side 16 sectors with a sector size of 256 bytes. (163840 bytes) To convert these raw disk images to solid d88 format you could use the supplied d88convw program D88CONVW 1.00
Free to use; no warranty or responsibility D88CONVW -raw_to_d88 -ftracks,sides,sectors,sectorsize|-fpx8|-fnec source dest The tracks*sides*sectors*sectorsize must match the raw filename size The -fpx8 option will specify the Epson PX-8 320K format -f40,2,16,256 The -fnec option will specify the NEC PC-6001 140K format -f35,1,16,256 so if you have an raw image called 'floppy.sf7' you convert it like: d88convw.exe -raw_to_d88 -f40,1,16,256 floppy.sf7 floppy.d88
this will result in a floppy.d88 file of 174768 bytes. Personally I think that the BlueMSX emulator offers a much better experience with the emulation of SC-3000/SF-7000. |
