I'd be very interested if anyone has working Master versions of Jetpac, Boffin
and Banjax.

Best wishes,


Ian

I just had a quick look - the version on the StairwayToHell site seems to
run OK on the Master, apart from a corrupted character set (but it looks as
if it has already been modified, by the look of a whole sequence of NOPs at
the beginning of the code).

Hac-Man in the Micro User published a Master conversion hack, which is good
for the original tape release:

You might be able to see what it's doing if you disassemble the patch, and
see what you missed.  It seems to me that the main problem is just getting
the Beeb character set at &C000..&C2FF (which is what lines 100-180 of the
patch are doing).  The rest of the code just seems to be involved in
getting round Kevin Edwards' evil protection!
