Does anyone have any thoughts on the advantages/disadvantages of ARM code versus THUMB code? It seems to be generally accepted that Thumb is more efficient...
... Thumb is also more efficient from EWRAM. Code running from EWRAM drains the battery much more slowly slower than code running from ROM, even though it...
... depends on your update code to be honest. Hardware sprites don't use mush in the way of CPU time :) the main problem you have is collision since that needs...
... When you look at it mathematically, sector-based collision is entirely equivalent to tile-based collision. The difference lies in how large the sectors...

Hi Dave, ... THUMB in ROM: Smaller, saves precious IWRAM. ARM in IWRAM: Generally about 4x faster than thumb in ROM. Putting ARM anywhere but IWRAM isn't a...

I dont think its a bad idea to let a compiler, good or bad, do your initial build from a high level language to asm and then tweak the asm for better...
