Hi all,

Here's a simple demo you can run in an emulator,
it comes as an XEGS 64K ROM image.

The graphics, 65 images in all over 8 screens of 8 images
and the last screen with a single image, come from the
C64 version of Bard's Tale but are in the 3 color (plus background)
of the Atari for now, but it gives you an idea of what they could
be like.

Enjoy,
Mark

I just used Antic 14 for the display in this simple demo. The graphics
mode for the BT intro method was done in 5 colour char mode
and so this is what the game would use too, therefore yes they
could be made a little more colourful. The problem at the moment
was that I hadn't figured out where the C64 gets the palette from.
Sprite under/overlays could be used but more hassle than its worth
IMHO. They will be used for the duration spells icons. The demo
also includes the images uncompressed wheras the C64 uses some
weird RLE and interlaced compression format to hold these images (basically most of the NMxx files on the disks).

Regards,
Mark

Here's an example for all to see...

img.c = the decompression program, takes a filename as an argument.

nm50 = original image file from C64

nm50.txt = Output produced by "img nm50 > nm50.txt" contains:
1) Trace of the decompression, the figures in brackets are the Y and X
pixel positions for the byte (e.g. divide X by 4 for the char offset).
2) Data in raster format for later compiling :)
3) Data in CSV format with two character patterns for each colour.

nm50.xls = Coloured version in Excel 8)

Regards,
Mark

PS. hopefully sticky this type of source out here
may inspire some more people to tinker in this way :wink:

Same principle of previewing in Excel.

Maybe someone can use these to test thier software
or multiplexing hardware sprite routines? 8)

PS: sticky = sticking ;)
