support for linking with different games/saves

[Royerson]

Gotta trade them pokemans

Being able to load a different rom for each player would be useful for pokemon and maybe other cases, and seperate saves even when playing the same rom would also obviously be useful.

Edit: just read #1 and it seems it used to be possible, but that those options are no longer recognized by RA at all and loading the core with -v doesn't show any subsytem info. Is it still possible?

Seconding this. The standalone TGB Dual supports different-ROM linking; it would be an essential feature for this core.

According to http://www.pokemonemulator.com/gameboy-color.htm,

TGB Dual 7 ENG can also be used to play and link GBC Zelda Oracle of Seasons / Oracle of Ages games

yes it supports it but it has changed a lot, there is now a subsystem api, this core hasn't been updated to support that api

[JamesTheAwesomeDude]

@fr500 So this is possible, just not implemented yet?

[andres-asm]

yes, the only core that implements this API at is bsnes for sgb/bsx

[andres-asm]

also RA doesn't really have the GUI hooked up for this yet, so only CLI support is available

[doritobob269]

So I was wondering if anything has changed with this feature being allowed as a "few" years have passed

[orbea]

@doritobob269 I think other cores might be the way to go now, I think Sameboy might have it, but I haven't tested it personally.

[andres-asm]

this one has it too.

[doritobob269]

How would one go about using multiple roms @fr500 ? Or how would one go about installing @orbea ? I am on my retropie btw.

[andres-asm]

Installing no idea we don't generally use retropie, just vanilla retroarch
