Newbie with No$GBA problems, so please lend a hand?

Hi :), I have recently discovered the whole new world of emulators and Roms.
I think it's all pretty cool, but also kind of complicated. I am having trouble with my emulator, No$GBA. I originally wanted to play Pokemon HG but i noticed the many other ds games I could be playing too. So I did some Googling on DS roms and found this fancy place but more specifically, I found Infinite Space. But when i downloaded it, and opened it with the emulator, all that came out was the window "No$GBA-FATAL" with message "The Rom-Image has crashed". HELP :(, please :'(?EDIT: NVM, I downloaded the full NO$GBA package and it starts fine, I'm just hoping it stays that way. Thanks to all that gave replies. Sorry if this is a common problem but I'm a newbie.

Try downloading the full no$gba package

And this might help you a bit

That errors only happen if your No$Gba Reset/Startup Entrypoint setting was set to GBA BIOS(Nintendo Logo),
and trying to run non-encrypted NDS rom.
Delete your 'NO$GBA.ini' file in your No$gba folder, and try to run the game again.
Infinite Space doesn't need to be encrypted to run normally.
