according to terraonion, md+ and already md+ patched games already work with original hardware. megasd not required for it specifically
something you misunderstood from their reply or your question wasn't clear. MD+ wont work on original HW. MD+ uses it's own proprietary interface.

MD+ games would be a massive luxury on the MiSTer , especially playing streets of rage 2 with the godlike OST and potentially 1 and 3 with awesome mp3 remixes

It definitely wouldn't, MD+ uses a proprietary command interface as well as tweaks such as undocumented flags in cue files to induce loops and an improved bank switching mechanism and so on. Please read the official development documentation from TerraOnion before claiming whether or not original hardware support things.

While there is no technical limitations (as far as I know of) that prevent these changes from being implemented in the MegaCD MiSTer core (a change I would personally welcome), the MegaSD is NOT (for all intents and purposes) original hardware.

Ok, so how the hell do i get Pier Solar to load? I've tried naming it cart.rom, naming another cart cart.rom, placing it in different folders, etc. If i load the megaCD core, and try to load a cue file, those work fine, but with that option i can't see Pier Solar to select it. The folder it's in will open, but display as empty. Other folders launch the .cue right away.

Any advice greatly appreciated

I have a folder called Pier Solar with the cart.rom file as well as the .bin and .cue files for the Pier Solar disc. As soon as I select the folder, it loads cart.rom and the disc image.

Ahhh, I see. thanks very much. I didn't realise there were more files required, and wondered how on earth they managed to fit CD-quality audio into 8MB, lol.

I'm still not understanding how to play Pier solar. I have the 4 bin and 1 cue file in the folder Pier Solar. Do I make one of the bin files "cart.rom"?

There's an actual cartridge dump that you need in addition to the disc image.

So you'll have 6 files total in the folder.
.cue
.bin x4
and then the cartridge dump renamed to cart.rom

Basically, you want a folder like /media/fat/games/MegaCD/PierSolar (or whatever) that looks like this:

2021-01-28_10-29-03.png (55.59 KiB) Viewed 4264 times
(or if you are using CHD, then substitute all the cue/bin files I have in this with the chd file)

Cart.rom is the rom for Pier Solar for sega genesis, just renamed.

I'm actually really enjoying Pier Solar game. I also have the original cart running with my mega cd.
