| Summary | 08851: trs80l2 trs80m3 trs80m4 coco: DMK Disk format detection rejects single-sided DMK files | ||||
| Description | MAME fails to identify single-sided DMK disk image files and rejects loading them. | ||||
| Steps To Reproduce |
Try to load a DMK file e.g. mame -w trs80m3 -flop1 TRSDOS13.dmk Results in: Fatal error: Device 5.25" double density floppy drive load failed: Unable to identify image file format |
||||
| Additional Information |
At least one problem: dmk_dsk.cpp checks for byte 4 to be zero but that byte contains flags (e.g. single-sided) The "i =4" below should be "i = 5" for (int i = 4; i < 0x10; i++) { if (header[i] != 0x00) return 0; } Introduced by wilbertpol in this commit: https://github.com/mamedev/mame/commit/699b8b5345061216c29e2ebdc5bb7e38350b048e There may be other problems but this is the most likely. |
