Cosmacuino works with embedded 1802 code in high flash

Managed to get a short 1802 program going that starts off in mega's RAM and carries on above avr program in flash. PLan is to have RAM as just a place to leap up to$4000 and above on the 32K m328p, as well as a stack and short buffer place.

This program:
C:\Users\Dell\Documents\Arduino\PB_SketchApril12\CDP1802e93\CDP1802e93.ino

acts as ROM and RAM for 1802. Delivers instructions. Problem is there's not enough ram on Arduino nano, 2k, where this program is eventually going to live so I've just used a ram buffer called vRAM[] to start things off then hand over to program above $4000. Currently, on the mega which has 8K of static ram, a buffer of 1024 called vRAM[1024] holds temporary 1802 code.

This is the report from avrdude:
Sketch uses 13118 bytes (5%) of program storage space. Maximum is 253952 bytes.
Global variables use 3077 bytes (37%) of dynamic memory, leaving 5115 bytes for local variables. Maximum is 8192 bytes.

The .ino file above is actually extended up to $4000 where main 1802 code is burned in. In the gap between the last byte of the arduino code viz. $333E=13118, and $4000, filler bytes are inserted. Currently zeros.
