done! here is bin2cas.py : http://pastebin.com/3j8TZkSt
the problem is i think the last checksum value is wrong, and its result is
providing an i/o error

for testing, i were trying with 6kb files, and loading into
'pmode3:screen1,0' display area with:

10 pmode 3:screen 1,0
20 cloadm"",1536

(i think the display address is changing sometimes, and i don't know how to
load directly to it)

if someone can help finding the bug, please do, since i humbly think this
tool can be useful for many CoCo2 users and retro coders
thanks,
p.
