Simulate having a certain GBA game in Slot 2 [Pokémon D/P]

[RavenousPonies]

Is there a way to simulate having a certain GBA game in Slot 2? Specifically, I'm trying to get Pokémon FireRed in Slot 2 while I'm playing Pokémon Diamond, this is because certain Pokémon can only be caught if you have older Pokémon games in Slot 2.

Is there a way to do this with DraStic? If not, is this feature planned to be added in the future?

Thank you!

Yes, it's supported. From the readme:

6. Slot 2 Cartridges

The slot 2 function allows inserting a virtual cartridge into an emulated slot 2 cartridge slot, which was present on original Nintendo DS and DS Lite units.
Usually, this will be used to load Gameboy Advance games, which enables bonus features or save file transferring for some games.

Slot 2 cartridge files should be placed in the sdcard/DraStic/slot2 directory.
If a file named <ROM file>.gba is found, it will be loaded when <ROM file>.nds (or .zip, .rar, or .7z) is loaded.
If a save file named <ROM file>.sav is found it will be loaded in the backup memory portion of the cartridge.
The save file format is raw without any header and should be compatible with .sav files produced by VBA or gpSP. SRAM, FRAM, and flash are supported as save types.

If <ROM file>.gba is not present slot2.gba (if present) and slot2.sav will be loaded by default.
