So I have what i believe is a bug in how systems are handled in MAME (possibly). My current focus is with the ZX Spectrum, however I have seen the same behavior with some other systems.
The problem comes about due to the media types (-listmedia) reported with the base system. In the case of the ZX Spectrum, these are as follows (These work just fine);
snapshot (dump)
quickload (quick)
cassette (cass)
Now, when I add a peripheral slot device that contains a floppy disk into the systems INI file (See below);
exp disciple
exp:disciple:fdc:1 35dd
exp:disciple:fdc:0 35dd
Then run the mame64 spectrum -listmedia, it reports the following;
SYSTEM MEDIA NAME (brief) IMAGE FILE EXTENSIONS SUPPORTED
---------------- --------------------------- -------------------------------
spectrum floppydisk1 (flop1) .mgt .dsk .d77 .d88 .1dd .dfi .hfe .imd .ipf .mfi .mfm .td0 .cqm .cqi
floppydisk2 (flop2) .mgt .dsk .d77 .d88 .1dd .dfi .hfe .imd .ipf .mfi .mfm .td0 .cqm .cqi
printout (prin) .prn
snapshot (dump) .ach .frz .plusd.prg .sem .sit .sna .snp .snx .sp .z80 .zx
quickload (quik) .raw .scr
cassette (cass) .wav .tzx .tap .blk
You can see that floppydisk1 (flop1) and floppydisk2 (flop2) have been added to the list of available media types. All makes sense so far. And if you run MAME and select a floppy disk image through MAMEs own interface, everything works as expected.
The problem arises however when you try to run the same flopp disk image using the MAME command line as follows;
C:\Temp\mame>mame64.exe spectrum -flop1 D:\Mameui64\roms\spectrum_cass\disciple.mgt
Error: unknown option: -flop1
You can see that even though the flop1 media type exists, MAME doesn't accept it. It seems as if when invoking the MAME command line like this, MAME is not taking into account the additional media types added via the settings in the spectrum.ini file. I know that INI file is correct as it works fine under the MAME gui itself.
Can anyone provide some knowledgeable advice on what's happening here and if indeed it is a bug?
Cheers.
