I think this indicates that your program doesn't cover all necessary registers (?), especially because I was unable to re-set normal VGA mode $12, which should be "standard"!? Anyway, if you are planning a new version of TWEAK: what about a little TSR to directly grab the VGA's register contents from a running graphic program? >>I would need a mode 432x270x256. (BTW: How did you came to that odd >>value "432"?). > I tweaked the 800x600x16 down to 400x600x256, then increased the screen > width until the screen started to flicker, i.e. at 432x600. > The number of screen lines is the most easy to tweak to what you want, > although I can't remembr the exac procedure/registers. I'll check into it. Thanks! (But by what you said, I'm stunned why 432x600 works, but 400x600 does not!) BTW: did you ever succeed in higher x-resolutions then 432 for 256 color modes (you know, I need that damned 1.6:1 aspect ratio...) cu, Kai +--------------------------------------------+-------------------------------+ |Kai Rohrbacher, University Karlsruhe/Germany|God is dead! - Nietzsche | |E-Mail: S_ROHRBACHER@IRAVCL.IRA.UKA.DE |Nietzsche is dead! - God | | UKB8@DKAUNI2.BITNET |Nietzsche is God! - Dead |
