MVGAVU v4.4 SQZGIF v3.0 GIFPUB v4.1 GIFHEX v1.1 The following utilities indirectly interact with the VGACAD.

VGACAP v7.5-7.3 * BUGFIX: Trident SVGA bank routines were still flawed (we tried to accomodate the rare BR version of the TVGA chip), resulting in erroneous bank switching; corrected by restoring the standard 64KB TVGA 8800/8900 banking code. * Added a new 'Trident' SVGA bank switching mode labelled 'Zymos'; this is essentially similar to Trident 8800/8900 chipset BUT with similar WRITE/READ bank switching routines. * BUGFIX: Video7 1024x768x16 grabs required a different bank switching routine; added 16-color bank switching code. * BUGFIX: C&T 452/453 1024x768x16 grabs required a different bank switching routine; added 16-color bank switching code. * Added FAST SVGA 1024x768x256 capture funtionality. * Added FAST SVGA 1024x768x16 capture funtionality. * Added FAST SVGA 800x600x16 capture funtionality. * BUGFIX: SVGA C&T 452 and 453 bank routines were flawed; corrected. * BUGFIX: When VGACAP is loaded and one or more files are saved, subsequent reloading of VGACAP would be accepted (ie., two or more VGACAP resident files would be permitted); corrected. * Added Ahead-B chipset support (VGA Wizard). VGAFIL v2.5-2.3 * MAJOR BUGFIX: Some combinations of DOS and environment variables resulted in "0" lenght PCX, BMP and TGA files (something to do with too many or conflicting DOS file handles); corrected! * FASTER PCX encoding. * Avoids sign-on screen if REGISTER.OVL is detected and verified; saves you a keystroke. * Customization menu updated to accomodate 'Zymos' setting. VGACAD SYSTEM v2.4 UPDATE ************************** VGACAD (Main) Update v2.4 * BUGFIX: VDISK module did not accept changed palette from MVGAVU; corrected. * BUGFIX: Users with minimal "low" RAM (eg, 32KB free RAM after runnign VGACAD) "hung" when chaining to GIFHEX or GIFPUB at the VDISK Module. Corrected; most RAM buffers used by VDISK are now deallocated prior to chaining to any "chainable utility" via VDISK. * BUGFIX: LARGE hard disks users (>32Meg) or users with hardware 'hard disk caching devices' experienced SEVERE problems with IMGPRO functions involving the saving or loading of image data. This caused the infamamous "ERROR 5 at VDISK" or "blank"/"trashed" screens saved to TEMP files. The "/SL:" option now triggers direct disk/video RAM to go through slower but safer LOW memory buffers to avoid "mix-ups" with hardware caching techniques. To trigger "cache-compatible" routines, ALWAYS use the "/SL:" option: eg.; VGACAD /SL:1 * BUGFIX: Trace/Fill function would 'hang' if the "seed" point had less than x 2x2 pixel clearance; corrected. * BUGFIX: EXTCHAIN did not detect and verify REGISTER.OVL file; corrected. VGAFIL v2.2 * Adds "-H" option for "hex" (ie., 16-color GIF encoding. No need to rename files to NYBLSCRN.* anymore; now you encode as many as you want in one sitting without getting out of VGAFIL. VGACAP v7.2 * FAST VGA 640x480x16 grabs - Automatically detects VGA 640x480x16 mode and jumps to appropriate routine. - Works in BIOS or ANY SVGA hardcoded setting. * BUGFIX: Trident 8800/8900 and Zymos routines for fast SVGA grabs were flawed; corrected. VGACAD SYSTEM v2.30 UPDATE ************************** VGACAD (Main) Update v2.30 * Total overhaul of IMGPRO module. Mode selection now follows MVGAVU (v3.0 and up) user interface.

Oak --------------- (no examples) * New Chips & Technologies support for 452/453 versions. * Chips & Technologies 1024x768x256 mode added. * New Chips & Technologies support for 451/455/456 versions. * Genoa GVGA 6100, 6200, 6300, 6400, 6600 chipset support. These cards are radically different from the 5x00 series. * Headlands/V7VGA4 (Video7 Version 5 chipset) support added for those with Video7 1024i SVGA cards (or clones, if any). * Video7/V7VGA (Version 1 to 4) chipset support modified for increased compatibility, read/write operations and speed. * BUGFIX: Tseng 4000 was in write bank only; this has been modified for READ and WRITE bank operations. VGAFIL v2.10 * BUGFIX: When VGAFIL was used in COMMAND LINE mode and the RAW files were not located in the default directory or drive, "0 x 0" images were encoded and subsequent system "hang" resulted. This has been corrected . * Adds "-C" to configuration option to maintain common interface with MVGAVU and other utils we will release. * Supports Targa 16 (uncompressed TGA) format for those who want to edit/modify SVGA screen grabs with XGA, Hercules Graphics Station, Targa and other cards that support 32KB, 64KB, or 1.6MB colors ! VGACAP v7.10 * SVGA 640x480x256 and 800x600x256 hard-coded for DIRECT memory/bank access; captures in about 2-3 seconds (based on SX with 28 ms. hard disk). The following SVGA chipsets are supported and can be configured with VGAFIL. ATI 18800/28800 --- VGA Wonder, Tatung, Altec, Gateway, TeleMart, TriStar...

Zymos TVGA 88/8900- Imtec, Logix, Maxon, Prism, HiRes... Everex EV678 ------ Everex Viewpoint Oak --------------- (no examples) BIOS -------------- (100% BIOS pixel read & palette usage) * Custom Western Digital PVGA (Paradise) support for WD90C01, WD90C10 and WD90C11 chipsets; forces single bank select just in case you capture while viewing with a program that uses the dual bank switching mode or new 800x600x256 mode supported by WD90C11 chip. * Genoa GVGA 6100, 6200, 6300, 6400, 6600 chipset support. These cards are radically different from the 5x00 series. * Headlands/V7VGA4 (Video7 Version 5 chipset) support added for those with Video7 1024i SVGA cards (or clones, if any). * Video7/V7VGA (Version 1 to 4) chipset support modified for increased compatibility, read/write operations and speed. * New Trident TVGA 8800/8900 chipset support. Forces 64KB bank switching mode and adjusts for the weird bank numbering scheme. Customized for read bank operations. * Optional Zymos/Trident TVGA 8900 chipset support using a linear/normalized 64KB bank switching scheme (just in case some chipsets fix/normalize the weird bank numbering scheme). Customized for read bank operations. * New Chips & Technologies support for 452/453 versions. * BUGFIX: Tseng 4000 was in write bank only; this has been modified for READ and WRITE bank operations. VGACAD SYSTEM v2.20 UPDATE ************************** VGACAD (Main) Update v2.20 * BUGFIX: Some 386 DXs were having problems saving and loading BLoaD screens directly to or from video RAM (probably some memory cache method ?); all routines in VGACAD using this approach have been changed. * BUGFIX: Some OEM SVGA/VGA cards were having PALETTE read and write problems (despite register-compatibility claims); this is now avoided by BIOS routines being the DEFAULT. Users opting to use FAST direct hardware palette read/write can do so using the "/P" option. * BUGFIX: After viewing a virtual screen section and subsequently decoding a new image the virtual screen section was "matched" with the worng palette; this has been corrected. * BUGFIX: Saving ANY virtual image smaller than 640x400 resulted in a corrupted image; this has been corrected. * "/R" command line option is now the default. If you specify the "/R" option, VGACAD will reserve an additional 64KB of RAM to speed-up certain functions. VGAFIL v1.3 * BUGFIX: Some OEM SVGA/VGA cards were having PALETTE read and write problems (despite register-compatibility claims); Palette read/write functions now follow whatever setting (Slow BIOS or FAST hardware access) has been triggered with VGACAD. VGACAD SYSTEM v2.10 UPDATE ************************** VGACAD (Main) Update v2.10 * BMP (Windows 3.0 file format) 256-color support - BMP virtual screen loading/importing (to 32KBx32KBx256). - BMP conversion/encoding/exporting (to 2048x2048x256). - Automatic 1:1 aspect ratio correction. * Transparent cut & paste ("lasso" effect) added to full- screen SVGA/MVGA image processing. When using the SVGA/MVGA iPut ("paste") function, pressing BOTH mouse buttons instead of simply pressing the LEFT mouse button will paste the image with a transparent background. THIS NEW FUNCTION DOES NOT MATCH COLOR PALETTES. USE ONLY "CLIPS" THAT HAVE BEEN COLOR MATCHED. * ZOOM ERASE MODE - Selecting COLOR 0 in Zoom Mode is now allowed. It can be selected from the colorbars or from the color map. This is particularly important in maximizing use of the SVGA/MVGA transparent cut & paste function. * Enhanced SVGA/MVGA rectangle definition routine. * Fast SVGA full-screen update/save/load/undo when SVGA video mode matches the virtual screen dimensions in the following "standard" SVGA modes. - 640x400x256 - 640x480x256 - 800x600x256 * BUGFIX: When decompressing PCX SVGA images, the destination virtual disk was not checked for adequate disk space. This has been corrected. VGAFIL Update v1.2 * BMP (Windows 3.0 file format) 256-color support VGACAP Update v6.1 * 100% BIOS-compatible function for palette access has been restored (ie., same as VGACAP v5.0 or v4.0) when slower but safer BIOS configuration is selected.
