If I'm right, then whether or - not the error happens depends entirely on when the previous demo - effect ended and the state the color palette was left in. - -================================================================================ - THE FOLLOWING BUGS ARE FIXED! -================================================================================ - -VGA BUG: Exotic VRAM clearing tricks do not work, leaving "garbage" on the screen - - - Abaddon: Cycling! - - Failure to clear the screen is visible when the VGA split-screen pans upward. - The "loading" graphic and other garbage contents are visible below the - animated VU meters where on real hardware that part of the screen would be - blank. - - NOTE: This is still a problem with machine=svga_s3, but fixable by setting - machine=svga_et4000 instead. I'm not sure at this time whether the - demo has the same problems on real hardware or not. - - - Surprise! productions, The Good, The Bad, & The Ugly - - There are two parts with rotating wireframe meshes that make use of VGA - palette trickry to create "motion blur". Failure to clear the screen results - in a wireframe mesh with a border of garbage pixels that flicker. - - - Optic Nerve (demo) - - At the start of each demo part, when displaying the title of that part, the - demo fails to clear the screen. Result: demo title with contents of the - previous screen or title screen around it, garbled due to palette mismatch. - - NOTE: This is still an issue with machine=svga_s3, but you can - eliminate the problem by setting machine=svga_et4000 or running - the demo from an MS-DOS 5.0 or 6.0 bootdisk. MS-DOS 6.22 may cause - stability issues. Windows 95/98 DOS mode is certain to cause the - demo to crash. - - - Impact Studios: Legend - - Failure to clear the screen causes 3D dot fields to overdraw into an orange - flickering ball. - -VGA BUG: Failure to save and restore VGA text screen contents - - - Microsoft Windows 95 boot logo - - Windows 95 is able to show the boot logo, but when restoring the VGA text - console, the contents are all messed up. Why? - - - Microsoft Windows 3.0/3.1/95/98 - - Running the DOS prompt in a window works, until you move the mouse cursor - over or near the DOS window. If you go back to fullscreen, the extended - character set is missing. If you go back and forth 2 or more times, the - character font is missing entirely. - - If any DOS program writes to the screen the contents appear as garbage at - the top of the Windows desktop. Whatever normally prevents the DOS program - from affecting the screen by Windows is not triggering in DOSBox and it - may be the source of corrupted VGA states. - - Weird crashes when you move the mouse cursor over the window do NOT happen - in Windows 3.11 Windows for Workgroups if 32-bit disk and file access is - enabled. - -VGA BUG: Switching to the DOSBox keymapper, then back, results in failure to redraw - emulated VGA output. - -VGA BUG: Active display area cuts off right margin for Do Whacka Do - - - Do Whacka Do works perfectly except that the rightmost 8-10 pixels are cut off, - which makes it a bit difficult to read the scroller at the bottom of the screen. - -
