yeah same here . shining force feather and GTA .

Seph's links are rather useful, may have been good if there was an explanation with them but just try to update you firmware with the bottom link of Seph's and if that doesn't work then you may want to consider using YSMenu for the R4 i think that may work. But it would help if you gave us more details like the flashcarts you're using because both games have problems. GTA has a prepatched rom if you read the forums:

There is a link about page 12 to a site called adrive, that has a fully working patched rom, try that, it works on R4, but as for Army Men i consider trying YSMenu, if that doesn't work then I'd skip that one. From the reviews it isn't any good anyway.

I got GTA to work by doing the arm7.bin patch. As for army men I have an R4 sdhc and when I pick that game it loads up but the screen just stays black and nothing happens after that.

Then read the fixes.

how abut shining force feathe r?
