No i don't think so by reading your post
it depends on what r4 you have
I had a R4 SDHC with firmwire 1.26 from r4sdhc.com now
(my Ds has been stolen so I'd had to order a new one also a new R4)
I have a r4 SDHC upgrade which means i have a new firmwire from:www.r4rts.cn
I think you need the cheat.dat file and when you start your DS and you can't see you
3 boxes "GAME Multimedia and Boot Slot 2" I think you have the wrong firmwire
for your r4 you must look on you r4 package which site it says to find your firmwire
if you can't find it i shall name a few sites :
http://www.r4rts.cn (this is the site for my new R4) -----> this version uses usrcheat.dat
http://www.r4sdhc.com -------> this version uses cheat.dat
An other common problem with R4 is not showing its cheats you can solve that by removing
cheats that you don't use and start with the (J) cheats and most of the time when you shrunk your cheatdatabase it will show its cheats
