Getting old software/games running on older hardware.

Hi Doc, thanks for the program! I wrote a little utility for you, CGAView. Maybe it is somehow useful to you.
It is fairly simple and supports displaying the alternate palette, too. And any XT machine with CGA.
But for some reason, it doesn't like all images. In this case, it might be necessary to
add a frame (or a thin line at the top and the bottom) to the images to fix that.
So don't expect too much, it is clearly horrific designed and still a work-in-progress. :sweatdrop:
Edit: Adding a 28pix wide, non-black (cyan) coloured line to the first row seems to fix the issue, too.

thx! I'll try it. The "more color" mode in calgames is really intersting because it's rgb-cga. Is there another game that uses it?
I tested some "tandy-related" stuff on my schneider euro pc with 1084 (CGA) and some textmode-things really work.
I will share it with you soon.

i believe Frogger also uses similar but more simpler trick.
It change the background color into Light Blue on top-half scan, and then to black on lower-half scan. So you have 5 colors (Black-Green-Red-Brown-Light Blue) within 320x200 CGA graphics mode.

changing the background-color is a nice trick. I think they did the rasterbars in the cgademo (codeblaster) with this trick. Very clever and really nice for cga.

Ok, take your time. I'm open to any(ones) suggestions also. Currently, it can already show images from the command line, btw.
There, it shows the pictures created by the converter program you posted, along with the matching standard palette.

Thx. I'll have to choose the palette before watching (btw. does not in boxer/dosbox on my mac, therefore no test on real hardware yet, but will soon follow).
Is it possible to code the palette/switch to F1-F3 and changing the background with F4 on the fly (wich means while watching the image)?

Not exactly what you asked for, but Great Hierophant made a post on his blog about games using the 16 color modes

Hello and Merry Christmas everyone! :)

I've found a cute, little GIF picture viewer for CGA systems.
It also can do grayscale and has additional VGA & Hercules support..
File name is "grey15.zip" and can be found here.
The Hercules fans among of you may also have a look at HercView.

So long..

Best regards,
Jo22

PS: I've updated CGAView, too.
I'll add it here, since I'm nolonger allowed to edit my earlier post.
Edit: Second upload (some typos fixed)
