Subject: Re: Tweaking the JSW engine: One for the experts
Ok, so I put the machine code in bank 0, offset #d800.
And then, in offset #defd,
1) Which bank should I use? 3?
2) What numbers should I enter? 00 d8? d8 00?
I tried doing it twice, following your new directions, and got two
different results, both of them wrong. :)
Thanks a lot, John. I will put you in the game credits.

1E00 + C0FD = DEFD
So, I have to modify bank 3, offset #DEFD
5) Reserve a memory page: let's use #d800
6) Enter in bank 3, offset #DEFD (This address defines Room 47)
No. Put the machine code in the memory page you have reserved -
in your case, bank 0, offset #d800.
7) Go to offset #C2FD and enter
This should be where the #DEFD comes in.
