I tried to run DSLinux on Dualis, but i get a blank screen, is there someway to run dslinux on dualis?

I tried running DSLinux on iDeaS, DSemu, Dualis, and NDeSmuME, but it would not run. Maybe you could try No$GBA. If that does not work, which I predict will happen, I'd say that DSlinux only runs on actual hardware.

On the first release of dslinux, was runned on iDeaS, but the new versions doesnt work.. In no$gba if i get a rom file with more than 1MB, its say the rom was crashed... and the dslinux have 1.9Mb...

And other question, on Dualis how to use GBAMP emulator? Its have a option, but i cant use...

For No$GBA, you may need the NDS bios files, which I will not give you a link for, then it might work. Might.

For Dualis, I believe the GBAMP option under "Memory > Compact Flash Device: GBAMP" Is meant to improve compatibility with homebrew games that are made to run on the GBAMP. The emulator uses it by default.

Ok, i have the bios file, i will try.

GBAMP emulation should be enabled by default and simply means that ROMs that use the GBAMP to access data on a compactflash card when run on a real DS should be able to do so in Dualis as well. It's strictly a feature for hobbyists, since no commercial DS ROM that I know of uses the GBAMP.

Its not for a comercial DS ROM, i tryed to run some homebrew apps which they use a CompactFlash card, i dont know where i put the files which needs to be on CompactFlash...
