No. That dicussion was the problem of making an SD cartridge with no battery, or fitting everything on the cartridge. EDGB does have a battery, so that's not a concern. The problem here is how much SRAM space the cartridge is assigning to the running ROM. Currently it can assign at most 32 kB. The SRAM chip in the cartridge is 128 kB big, but half of that is reserved for system data. This means the biggest size SRAM LSDj could use is 64 kB. This is ok. It's enough for a couple of saved songs. But this would most likely require a firmware upgrade/modification for EDGB, which I'm hoping to be able to do.
64 kB is the same the white Nintendo Power cartridges expose to a program like LSDj. Incidentally, they also have a 128 kB chip which may be possible to unlock, but that's a story for another day.
Did you need an Everdrive GB to test with?
I have one I'd like to donate to your cause - would be fantastic to get it working with LSDj.
Edit: I tried LittleFM 0.5 and it complains it doesn't have 128kB of memory, so it looks like the Everdrive is eating up enough for LittleFM to freak out about and LSDj to only allow you to reset the SRAM?
Idk what I'm on about, but hopefully that's a good start to solving this problem.

I need three new carts so I'm very interested in the outcome.

What is little FM? haven't used it before...
Considering that LSDJ works ok on real mappers, this is something you should forward to the flashcart dev. Have you the option to use a mbc5 mapper?
Yes I did. In fact, the cartridge uses that mapper by default. When I use that option, the load/save option dissappear.
Another possible option, which kind of sucks but should work, is to use one copy of the ROM per song.
It sucks.
Well, I think Im going to contact with krikzz about it. The problem its that he is going to need the rom to test it because it seems that the demo version doesnt have the load/save feature.
Will it be ok to send him a copy of the last version to krikzz? well, I think I will need to contact to both developers (johan k and Igor) for this problem.
