OK, for anybody that has a CoCo SDC and have not had a chance to check out the
running of ROM PAKs from the CoCo SDC flash banks, here is a small random
collection
of ROM games (5) that I hex edited purely to see a program running from flash.

On the .DSk file I have a modified version of Darrens BASIC loader example from
his blog site.

So if you run"flash.bas on the .DSK, all you have to do is enter the file name
you want and next select the flash bank (I have restricted the options from
3 to 7.

0 being the boot SDC-DOS, 1 being normal extended DOS, and for me I have a
backup
copy of SDC-DOS in bank 2. 

so example,

:Place SDCFLASH.DSK on the root of the SD card.
DRIVE0,"SDCFLASH
RUN"FLASH
:Follow onscreen instructions,
:Select File Name
:Select Flash Bank 3 - 7

Once finished, to run the game simply type (assuming you selected bank 3),

run @3

Hope this is worthwhile to someone.

Cheers,
Shane
