I have just converted from DevKitAdvance to DevKitARM.
Yikes it takes ages to start my program now, it starts off as a white screen for ages then the program starts. Im guessing its when I'm loading in all my gfx data. Same code works on devkitadvance with no notice of delays
my compile code as follows:
arm-elf-g++ -O2 -g -mcpu=arm7tdmi -mthumb -mthumb-interwork -c main.cpp
arm-elf-g++ -O2 -mthumb -mthumb-interwork -g -specs=gba.specs main.o -lafm -o test.elf
arm-elf-objcopy -O binary test.elf test.gba
Any idea why it would do this? I was expecting it to be faster =(

The devkitARM r12 release has a bug in its startup code, specifically in the part that clears IWRAM (which is commonly used for global variables and the stack). There's a thread in Announcements and Comments that tells how to fix it. I think there are a few other kinks in r12 that I can't quite put my finger on yet; at the moment, it might be easier for a beginner to downgrade to devkitARM r11.

Just want to say Tepples, thanks again for always being so quick to responding and clearing things up for me (sorry for being a nag!)

tepples may be fast, but he sure isnt good at finding bands. Why not use kazaa if you want to find kinks' songs? I think you've forgotten GBAdev is for devving, and so is devkitARM, not illegal music downloading..
EDIT : It seems my rather frail attempt at humour has miserably failed. the kinks are a band..
Go on, delete me please..

eh?! what the hell is kinks song? and who said ANYTHING (apart from you) about downloading illegal music?

I think it had something to do with kinks in devkitARM r12 (defined by Wiktionary as "A difficulty or flaw that is likely to impede operation, as in a plan or system") vs. The Kinks.
Anyway, Kazaa has always sucked; there are better places to get, ahem, "test vectors" for GSM Player.
