i wanted to download sonic and sega all stars and it didnt work so was told to download wood r4 so i did and the game still dosnt work is it the game or have i downloaded it right here is what i diddownloaded wood r4 extracted file
placed it on to my r4 carddid i need to delete some old files on my r4 card or add my games somewhere else?

First, which R4 do you have? Wood for R4 will only work 100% on original R4 cards, not any clones (ie: R4 Upgrade, R4 SDHC). Once you verify that it is in fact an original R4, back-up everything on your microSD card. Proceed to format the card.After that, place these files on the card:_rpg folder
DSMENU (name might be a little off), but it is the Menu one.
NDS Rom folder
Any homebrew you may haveNothing else should be on the card. Nothing from YSMenu or anything else. If it still doesn't work, than you probably don't have an original R4, regardless of if you think you do.

There is a WOOD R4 for clones I think. And knowing how many people are using clones today, I think hes using one. Once again I say, first, reformat your microSD then put the two files; _rpg and _DS_MENU.DAT
Into the root of your microSD. Then try it again.

thanxs so much it worked :)
