Subject: Re: How do you change the title screen ?
<< I have noticed that some people have
changed the title screen in their games.
Where it
said jet set willy 128 for example they have changed
it to the name of their game. >>
Which
games do you mean? The title screens are
done
differently in JSW128 and JSW48, and I've never seen anyone
change the JSW128 one (though it isn't too hard, at
least on a Spectrum +3 :-) ).
Anyway, the JSW128
title screen is stored at the start of TITLE.JS7, in
the following format:
* Bitmap: CODE
16384,4096
* 1st Attributes: CODE 22528,512
* 2nd
Attributes: as above
* 3rd Attributes: as above
When I was drawing the original JSW128 title screen, I
generated three screens on my +3 using Animator1 (a paint
package) and then wrote a little BASIC program to copy the
correct bits to an area of memory and save the result as
TITLE.JS7.
Changing the title screen in the 48k version
and ending up with something recognisable is much
harder.
<< Also can you use your own midis for music?
>>they wouldn't be MIDIs. As it is I only know of one
No. You can write your own tunes if you want, but
person who wrote tunes in the .TUN format used by
JSW128, and that's Ian Collier himelf. The tune format
for JSW48 is documented on Andrew Broad's site, and
various authors have written new JSW48 tunes (which are,
of course, simpler).
