No@GBA works properly...

...But apparently the roms I got do not. I've been trying to fix this problem, checked the faqs, but the problem is not of that anymore. I got the encrypter/decrypter, and done what's needed. I got the BiosNds7 & 9, But yet, when I want to play Disgaea DS for example, it say 'Error Ocurred while loading data'. Is there something I am missing?

Maybe you're using a very old version of that emulato since ROMs are not required to be encrypted/decrypted anymore, but keep in mind some ROMs, especially the newest ones, require to be patched. Also, they don't need to set save types manually. To get the latest version, click here or here.

I'm using the latest version of No$GBA, I forgot to tell ya. I've tried with the patching aswell. It results the same way.

EDIT: I tried patching it again, and got this message:
NDS Patcher v0.1 by ]{ain
Checking if arm9 is compressed...No
Looking for CARDi_ReadRom signature...
Not found, aborting
What do that mean?

I just used the 'NDS Loader' on dslazy that claim to have patched the game. But now, when I start the game, I first have to go through the DS meny and choose the game, and when starting the game, it say 'The Rom Image have crashed', and if I encrypt/decrypt it, it alternates between that, and showing 'Error Ocurred while loading data' again.

Since I cant edit:
I have now downloaded DeSmuME to see if the games work in this one, but I have a slight problem... I cant start it.
No, nothing with the program or so, but I just cant seem to find any exe files, for example desmume_nosse2.exe that the manual claim that it should have.

Nevermind, I downloaded 0.9.5 that had the exe files in it.

Alright, I can play the games now, but it's laggy... I use frame skip 2 to make the game run smooth, but the sound still goes as slow as the game would.

EDIT: Apparently it's because I am missing the last 500 mhz to have 2 ghz, and/or because of that I have an ATI card...
Is there any other emulator that might work for me, with
# AMD Athlon XP, 1466 MHz (11 x 133) 1700+
# 768 MB Available RAM
# HIS Radeon X1550 (256 MB)
then please tell me.
Thanks.
