Yes, sure it works on real hw, but those other chips he's using (74LSxxx) need to be simulated in megasd. Normally carts are just a rom connected directly to cart lines. Any other hardware present in the cart needs to be notified to megasd so it can enable that hardware simulation (for example sram chips, or banking chips). Otherwise it will work as a single rom cart with plain mapping.
You can try that rom in mame, that uses the plain rom mapping, and the same issue will happen. Other emulators probably enable the extended mapper for roms >4MB that is the maximum allowed in the normal addresssing range, but then it would break mortal kombat hack, so yes, per game fixes are always needed, becaude thr emulator or cart can't know which extra hqrdware the cart has. This happens to sram carts too. Megasd relies on the game sram header, but it's not right for some games. In a cart it doesn't matter becauee the hardware is there inside the cart, and the rom header does nothing.
Ok. But, do you intend to support this type of extended mapping?
As neodev said..it is supported, you just have to define it per game or it breaks other things.

Has anyone gotten Sonic Delta v0.47 working on the MegaSD? https://www.neto-games.com.br/rom_hack/ ... _40_mb.php

I tried creating a cfg file and setting Mapper=15 but just get a blue screen.

Didn't work for me, either.

It looks like v0.48 now loads. It gives a blue warning screen (I think about saving) that you can bypass by pressing "C" (I think the screen says to press start though).

Anyone know why save support isn't working on Mega SD? I see that Sonic Delta was updated for this: "The game should boot on chinese Everdrives without save support."

Neodev is aware of the issue and already knows how to fix it. I would assume a fix for the SRAM issue will be in the next MegaSD firmware update.

This hack is "special" as it uses the SSF2 mapper with SRAM.
