Killer7 in Dolphin - 2 Part GCM

[vbigcat]

I've searched far and wide for an answer, but I can't seem to find any instructions for combining or using a game that has 2 GCMs.

Killer7 wasn't originally a two disc game, so it won't work in Dolphin if I use either of the GCMs individually.

What can I do to get it running?

That title is a 2 disc game on Gamecube. On PS2 it was a single disc.
Gamecube discs can't hold as much data.

Ahhhh, ok that makes sense, thank you. So at some point it will ask for me to insert disc 2, and I should load a save with disc 2 running?

yep, a two disk game for the ngc hannah montana tampon box, single for ps2 as already stated.
redump.org will be a good place to view retail hashes for general use.
whatever roms you get, regardless of platform, use redump as a reference to check your gear.
it should be the same ideally.
good to get reassurances all the same.

okay, i have this game on PAL-EUR dump for ngc, and USA for ps2. (thanks murasame for your verified images.)
the ngc will prompt to save the game beforehand.
make sure you do before disk swap.
i've played this fully on the wii using a wode jukebox without so much as fart of an issue, and i was able to virtual-swap the images via the wode hw-gui without saving in advance, and it worked as if it was a retail job.
still, saving where possible is wise, in case of power outages.
if using an emu, snapshot save also, at least that's ONE massive plus emus have over the real-deal...
...memory snapshots/ram dump.
if the emu allows to save normally, do both.
all the best.
[edit]
you can load d-1 saves for d-2, but you'll be asked for it's other disk, vice-versa.
it won't damage anything, just kick you with a correcting message for the right disk.
