Nds4Droid + Gamecih

[Mikeeee1231]

Hello, I don't know if talking about emulators is allowed here but I'm going to try, just let me know if its not and or remove this post, So I tried the emulator '' nds4droid '' but I find it a little slow on a few games so I got an idea, gamecih speed hack but when i speed up with gamecih (its working with other games) it just not working, nothing change, why it do not change anything?

oh and Why I can't make gamecih 3 work? Gamecih 2 work but not the third one,  since i got a new phone, only the version 2 is working (and maybe 1, i haven't tried) and the version 2 I can't speed up (just for a few sec and it showing a message after).

Thanks for the help!
