Retroplayer:
If I had to take a guess, I would say the OP probably is thinking of storing stuff like the webpages, etc.. in the main flash. Actual code, I couldn't imagine many projects that would need more than 256K. So, if it data (audio, graphics, HTML, etc...) that will be filling up your memory, move that stuff to some external memory.
Well he did say
I am not talking strings and such, but large amounts of logic/code itself that would bring my code base past 256
