I've been dumping FMT software for about 7 months now and I've seen a lot of hybrid CD ROMs. However they're not cross listed if there is a single dump.
The problem with that is there isn't a way to ensure the CD ROM is listed in both databases. Actually all that occurs at this time is that the CD ROM has it in the comments.
For example, let's take a look at Fouge Vol. 2: Masuo per Masuo: Ikeda Masuo Hanga-shuu that I listed for the FM Towns
http://redump.org/disc/77917/
in the comments listed, whomever QA'd my dump we can see the following which is also on the CD ROM case:
Windows/Macintosh/FM-Towns CD-ROM
6MB RAM and 4MB HDD needed to run
This was also on the packaging material with system requirements and there are also operating systems files for this tri-brid CD ROMs
A lot of software in the early to mid 90s for Japanese retro computer's such as PC98, FMT, MAC, DOS/V and even regular WIN95 have at times hybrid or tribrid discs. In the case of Fouge Vol. 2: Masuo per Masuo: Ikeda Masuo Hanga-shuu it is only listed in the FM Towns sub-database but it isn't cross listed in the MAC and PC98 lists.
So what I'm requesting or proposing is a way where I can select a tick-box or checkmark in the NEW DISC submission where I can check other common Japanese operating systems and computers that it may be hybrid/tribrid for in the meantime since it appears my dumps that are hybrid/tribrid won't be double-listed. In the case of Fouge Vol. 2: Masuo per Masuo: Ikeda Masuo Hanga-shuu it would have MAC, PC98, FM TOWNS, DOS/V, X68000 ETC to ensure cross compatibility. That way any newer disc dumps could potentially count as a validation AND then be cross listed in the appropriate section
Example. Your best friend cyo submits a game called The Horde
http://redump.org/disc/10292/
r09 submits his under FM Towns and his is approved as such but also ticks off DOS/V and PC98 under tickboxes in new disc submission list under the same list of information that is filled out such as PVD, CUE sheet etc. Then cyo submits as FM Towns and ticks off DOS/V and PC98 under tickboxes but whomever is approving submissions counts it as a verification for FMT and starts new entry for PC9821 or even DOSV. However under this proposal 4 CD ROMs would be required to ensure 3 entries across the board.
