undocumented vga modes like 400x600 256c
due on an information provided from Wikipedia ( http://en.wikipedia.org/wiki/Video_Grap ... ing_tricks ), i'm trying now Fractint ( http://www.fractint.org ) on DosBox, which really provided the resolution 400x600 256c - i only tested it on DosBox, not real machine
my question is: how easy is to us accessing this 400x600 256c resolution (and other resolutions alike - these undocumentedl resolutions are really interesting for me) on FreeBasic, and running it fine on DosBox, or on a real machine running FreeDos?
and how easy can we use sprites, character patterns, vectorial drawing, palette colours and colour cycling, etc., there?

Re: undocumented vga modes like 400x600 256c
Did you try
Code: Select all
SCREENRES 400, 600, 8

well... http://img135.imageshack.us/img135/9615 ... osbox1.pngTJF wrote:Did you tryCode: Select all

and btw, isn't 'screenres 400, 600, 8' related to vesa? i'm interested in tweaked vga only, not svga or vesa...
Re: undocumented vga modes like 400x600 256c
I would try
before the SCREENRES statement. (Just a guess.)
Check Wiki
Code: Select all
SCREENCONTROL(SET_DRIVER_NAME, "VGA")
Check Wiki
Re: undocumented vga modes like 400x600 256c
You can Imagecreate a buffer for x*y pixels of say 8 bits. It returns a pointer to the base address in memory. You can then write a 32 bit word to that memory and load 4 pixels at the same time. Then Put the buffer to the screen. That will work under FB without dependence on hardware.
Code: Select all
Screenres 400, 600, 8
Dim image As Any Ptr = ImageCreate(640, 480, , 8)
ScreenInfo( , , , )
' write to the buffer at image
Put (0, 0), image, pset
' see the image

Re: undocumented vga modes like 400x600 256c
well, i tried this:
and got this:
Code: Select all
#include "fbgfx.bi"
screencontrol(set_driver_name,"vga")
screenres 400,600,8
dim image as any ptr=imagecreate(640,480,,8)
screeninfo(,,,)
'- write to the buffer at image
put(0,0),image,pset
'- see the image
locate 5,7:print"hello world!"
sleep

Re: undocumented vga modes like 400x600 256c
SET_DRIVER_NAME is part of the FB namespace. Try 'ScreenControl(FB.SET_DRIVER_NAME, "VGA")', or put 'Using FB' after the #Include line. Also, don't forget to ImageDestroy your image when you're done with it.
As far as I know, FB's graphics modes don't at all work the same as QB's. I believe it's all done with a backbuffer that gets copied to the screen, and palette modes are all just an array of bytes running top-bottom, left-right. Sprites, lines and palettes will essentially work the same way in all screen modes.

Re: undocumented vga modes like 400x600 256c
You are right: in fact, some VGA modes (like SCREEN 7,8,9,10,11,12) use bit-planar graphic (this solution is faster and require less memory if a pixel requires less than 8 bit), while screen 13 uses chunky graphics.counting_pine wrote: As far as I know, FB's graphics modes don't at all work the same as QB's.

Sprites, lines and palettes will essentially work the same way in all screen modes.
In qbasic, all commands were able to work both in bit planar and in chunky mode; in freebasic, only chunky mode is used (since gfx lib has been written mainly for windows and linux, that works always in chunky mode); the graphic buffer is always in chunky mode (in fact, it wastes some memory when less than 256 colors are used), and the VGA driver in mode 12 just convert it to bitplanar mode on the fly (like many rendering engines on the Commodore Amiga); it's an inefficient solution, but it allows to use fbgfx even in VGA mode with no need to rewrite all the commands (and since VGA mode is a legacy mode, there is no much need to have a better support).
a good document about strange vga modes can be found here:
http://www.programmersheaven.com/downlo ... nload.aspx
maybe some examples can be ported?

this tweak16b tool looks really awesome - sad is i'm not able enough to convert those code into freebasic code or inline asm there - thanks! :)

Re: undocumented vga modes like 400x600 256c
btw, here is a list of resolutions supported by Fractint 20.04.9 - sorry being as a picture only - there are some working very fine on DosBox (and i bet that they work fine on real "old" machines as well), and i really wished to have them available from FreeBasic/DOS (400x600, 320x400, etc.)
it seems they are accessible by inline asm with some out commands? if someone know how can we reach them, please share to us! :)
btw, here is the original fractint.cfg comes from there:
