ROM Hack Roms Not Reading Right

[Jinxxie]

I'm in need of help. I've just installed twloader and it works just great, but for some reason when I load some of my games it says something along the lines of: data not found. reinsert disc card.

Super Mario DS works but I can't seem to get some of the others to work. One of the games is My Sims Kingdom. The other is Final Fantasy Chocobo Island (I think).

Does anyone know how to resolve this issue?

Edit*
The ones that do work so far are Super Mario DS

The ones that do not work and keep saying reinsert disc card are Pokemon Diamond, Kirby Super Star Ultra, My Sims Kingdom, Plants VS Zombies, Final Fantasy: CHocobo Island,

Note: Brain Age 2 loads sideways which is really strange.. Is that how it's supposed to load or..?
Note: Harvest Moon: ISland of Happiness loads to a blank dark screen.

some games are not compatible with TWLoader, have you checked the compatibility list? I've also read some need donors rom for some, if you want to have almost full compatibility, get a flashcart.

You need a mkds rom for alot of them to be set as something called a donor room, which can be set from the twloader menu. Otherwise, twloader has a low compatibility list. I can guarantee Pokemon Platinum should work once the donor is set.

EDIT: also brain age is a sideways game.

If a game loads but says something about save data, memory or something along those lines, then you need either a donor ROM (Mario Kart DS for SDK 1-4 games like Gen 4 Pokemon) or a donor cartridge (for SDK 5 games like Pokemon Black)
