Firmware changed from using atari5200 to atar5200 - only have 8 characters!
use atari5200 as directory
Merged turbo freezer support from Hias. Working pretty well. PIA freezing not working yet though, so no joystick after freeze. Scoll lock to freeze.
Smaller firmware, thanks to Hias
Point cartridges at user dir, rather than os rom dir
Merged in first cut cartridge emulation support from Hias. Excellent:-)
Updated firmware
First cut of 5200 support for the DE1. Might want to share this with the Atari 800 verison - with a generic. PAL/NTSC PLL not working for some reason... firmware forked for 5200 - will be merged before commit
