R4i (Help needed and sorry if it's in the wrong section I dunno)

I have an R4 i card and i've noticed that a few games don't work and it's recently become a real pain. I wondered if anyone else had similar problems and knew if you could solve them. These are the problems.
LOZ:Spirit Tracks - There's no train menu
Heroes: Classes - Gets to the logo, music still plays but no screeen, it's all black
Sonic & Sega racers - Won't load errorcode=4
Disgaea - Keeps creating new .sav files

well for sega superstar racing i was able to make it work on my r4 ultra, i guess that the r4i is nothing different so this is what you do...first you need to download Akaio 1.5.1
i provided the link because this download makes the akaio program possible on a r4http://www.taringa.net/posts/juegos/4261103/Firmware-Akaio1_5-Crackeado-para-Clones-%28como-el-R4iNeo-etc%29.html
(Yes it is in spanish if you don't understand just use google translate)Once you finish extract it and now it is time to patch the game for the arm7 fix
(this will fix the "The saved data could not be accessed.")
Here the link to patch the game for the Arm7 fixhttp://www.linfoxdomain.com/nintendo/ds/?mode=desc&fileid=1785follow the directions and it should work because it worked for meonce you put the akaio 1.5.1 on you r4i and the patch game,
Open AKMENU4.NDS on your ds
select sega superstars racing
*when you select sega superstars racing hold X and the "loading" should turn red
If everything was done correcty the game should work.It did work on my r4 ultra v.155
hope this helps

Cheers mate! I'll try it now
