Have you checked that no other similar bug report(s) already exists?
[X] I have searched and didn't find any similar issues.
What operating system(s) this bug have occurred on?
Windows 10 Pro 21H1
What version(s) of DOSBox-X have this bug?
0.83.19 and 0.83.11 SDL2 Visual Studio 64 bit
Describe the bug
If you configure the game in SVGA mode using SETUP.EXE in the SCREAMER directory and launch it, it works correctly the first time by typing SCREAMER at the DOS prompt.
But if you close the game and try to launch it again, the game does not start anymore:
By the way, the old DOSBox 0.83.11 SDL2 Visual Studio 64 bit even closes immediately.
I tried to open the logging console and there are some messages about "ERROR BIOS:INT15:Unknown call" and "ERROR MOUSE:Unhandled videomode 69 on reset".
If the game is configured in VGA mode it can be closed and relaunched as many times as you want without closing the emulator.
Could the bug be related to this discussion https://stackoverflow.com/questions/43194265/dosbox-is-buggy-with-int-15h-ah-86h ?
Expected behavior
The game should always restart regardless of the graphics mode.
Steps to reproduce the behaviour
1) Configure the game in SVGA mode with SCREAMER\SETUP.EXE
2) Launch the game and play a little
3) Exit from the game
4) Try re-launching the program by typing SCREAMER at the DOS prompt.
Used configuration
# This is the configuration file for DOSBox-X 0.83.11. (Please use the latest version of DOSBox-X)
# Lines starting with a # are comment lines and are ignored by DOSBox-X.
# They are used to (briefly) document the effect of each option.
# To write out ALL options, use command 'config -all' with -wc or -writeconf options.
[sdl]
# fullscreen: Start DOSBox-X directly in fullscreen. (Press [F11/F12]+F to go back)
# fulldouble: Use double buffering in fullscreen. It can reduce screen flickering, but it can also result in a slow DOSBox-X.
# fullresolution: What resolution to use for fullscreen: original, desktop or a fixed size (e.g. 1024x768).
# Using your monitor's native resolution with aspect=true might give the best results.
# If you end up with small window on a large screen, try an output different from surface.
# windowresolution: Scale the window to this size IF the output device supports hardware scaling.
# (output=surface does not!)
# windowposition: Set the window position at startup in the positionX,positionY format (e.g.: 1300,200)
# display: Specify a screen/display number to use for a multi-screen setup (0 = default).
# output: What video system to use for output (openglnb = OpenGL nearest; openglpp = OpenGL perfect; ttf = TrueType font output).
# Possible values: default, surface, overlay, opengl, openglnb, openglhq, openglpp, ddraw, direct3d, ttf.
# autolock: Mouse will automatically lock, if you click on the screen. (Press CTRL-F10 to unlock)
# clip_mouse_button: Select the mouse button or use arrow keys for the shared clipboard copy/paste function.
# The default mouse button is "right", which means using the right mouse button to select text, copy to and paste from the host clipboard.
# Set to "middle" to use the middle mouse button, "arrows" to use arrow keys instead of a mouse button, or "none" to disable this feature.
# Possible values: none, middle, right, arrows.
# clip_key_modifier: Change the keyboard modifier for the shared clipboard copy/paste function using a mouse button or arrow keys.
# The default modifier is "shift" (both left and right shift keys). Set to "none" if no modifier is desired.
# Possible values: none, ctrl, lctrl, rctrl, alt, lalt, ralt, shift, lshift, rshift, ctrlalt, ctrlshift, altshift, lctrlalt, lctrlshift, laltshift, rctrlalt, rctrlshift, raltshift.
# clip_paste_bios: Specify whether to use BIOS keyboard functions for the clipboard pasting instead of the keystroke method.

# Possible values: true, false, 1, 0, default.
# clip_paste_speed: Set keyboard speed for pasting text from the shared clipboard.
# If the default setting of 30 causes lost keystrokes, increase the number.
# Or experiment with decreasing the number for applications that accept keystrokes quickly.

# sensitiveness of your device, i.e. the mouse is slower but more precise.
# Possible values: integration, locked, always, never.
# mouse_wheel_key: Convert mouse wheel movements into keyboard presses such as arrow keys.
# 0: disabled; 1: up/down arrows; 2: left/right arrows; 3: PgUp/PgDn keys.
# Putting a minus sign in front will disable the conversion for guest systems.

# frameskip: How many frames DOSBox-X skips before drawing one.
# aspect: Aspect ratio correction mode. Can be set to the following values:
# 'false' (default):
# 'direct3d'/opengl outputs: image is simply scaled to full window/fullscreen size, possibly resulting in disproportional image
# 'surface' output: it does no aspect ratio correction (default), resulting in disproportional images if VGA mode pixel ratio is not 4:3
# 'true':
# 'direct3d'/opengl outputs: uses output driver functions to scale / pad image with black bars, correcting output to proportional 4:3 image
# In most cases image degradation should not be noticeable (it all depends on the video adapter and how much the image is upscaled).
# Should have none to negligible impact on performance, mostly being done in hardware
# For the pixel-perfect scaling (output=openglpp), it is recommended to enable this whenever the emulated display has an aspect ratio of 4:3
# 'surface' output: inherits old DOSBox aspect ratio correction method (adjusting rendered image line count to correct output to 4:3 ratio)
# Due to source image manipulation this mode does not mix well with scalers, i.e. multiline scalers like hq2x/hq3x will work poorly
# Slightly degrades visual image quality. Has a tiny impact on performance
# When using xBRZ scaler with 'surface' output, aspect ratio correction is done by the scaler itself, so none of the above apply
# 'nearest':
# 'direct3d'/opengl outputs: not available, fallbacks to 'true' mode automatically
# 'surface' output: scaler friendly aspect ratio correction, works by rescaling rendered image using nearest neighbor scaler
# Complex scalers work. Image quality is on par with 'true' mode (and better with scalers). More CPU intensive than 'true' mode
# When using xBRZ scaler with 'surface' output, aspect ratio correction is done by the scaler itself, so it fallbacks to 'true' mode
# 'bilinear':
# 'direct3d'/opengl outputs: not available, fallbacks to 'true' mode automatically
# 'surface' output: scaler friendly aspect ratio correction, works by rescaling rendered image using bilinear scaler
# Complex scalers work. Image quality is much better, should be on par with using 'direct3d' output + 'true' mode
# Very CPU intensive, high end CPU may be required
# When using xBRZ scaler with 'surface' output, aspect ratio correction is done by the scaler itself, so it fallbacks to 'true' mode
# Possible values: false, true, 0, 1, yes, no, nearest, bilinear.
# euro: Display Euro symbol instead of the specified ASCII character (33-255).
# For example, setting it to 128 allows Euro symbol to be displayed instead of C-cedilla.
# doublescan: If set, doublescanned output emits two scanlines for each source line, in the
# same manner as the actual VGA output (320x200 is rendered as 640x400 for example).
# If clear, doublescanned output is rendered at the native source resolution (320x200 as 320x200).
# This affects the raster PRIOR to the software or hardware scalers. Choose wisely.
# For pixel-perfect scaling (output=openglpp), it is recommended to turn this option off.
# scaler: Scaler used to enlarge/enhance low resolution modes. If 'forced' is appended,
# then the scaler will be used even if the result might not be desired.
# To fit a scaler in the resolution used at full screen may require a border or side bars.
# To fill the screen entirely, depending on your hardware, a different scaler/fullresolution might work.
# Scalers should work with most output options, but they are ignored for openglpp and TrueType font outputs.

# glshader: Path to GLSL shader source to use with OpenGL output ("none" to disable, or "default" for default shader).
# Can be either an absolute path, a file in the "glshaders" subdirectory of the DOSBox-X configuration directory,

# advinterp2x, advinterp3x, advmame2x, advmame3x, rgb2x, rgb3x, scan2x, scan3x, tv2x, tv3x, sharp.
# pixelshader: Set Direct3D pixel shader program (effect file must be in Shaders subdirectory). If 'forced' is appended,
# then the pixel shader will be used even if the result might not be desired.
# autofit: Best fits image to window
# - Intended for output=direct3d, fullresolution=original, aspect=true
# monochrome_pal: Specify the color of monochrome display.
# Possible values: green, amber, gray, white

# Either a font name or full font path can be specified. If file ends with the .TTF extension then the extension can be omitted.
# For a font name or relative path, directories such as the working directory and default system font directory will be searched.
# For example, setting it to "consola" or "consola.ttf" will use the Consola font; similar for other TTF fonts.
# ttf.outputswitch: Specifies the output that DOSBox-X should switch to from the TTF output when a graphical mode is requiested, or auto for automatic selection.
# Possible values: auto, surface, opengl, openglnb, openglhq, openglpp, direct3d.
# ttf.winperc: Specifies the window percentage for the TTF output (100 = full screen). Ignored if the ttf.ptsize setting is specified.
# ttf.ptsize: Specifies the font point size for the TTF output. If specified (minimum: 10), it will override the ttf.winperc setting.
# ttf.lins: Specifies the number of rows on the screen for the TTF output (0 = default).
# ttf.cols: Specifies the number of columns on the screen for the TTF output (0 = default).
# ttf.wp: You can specify a word processor for the TTF output (WP=WordPerfect, WS=WordStar, XY=XyWrite) and optionally also a version number.
# For example, WP6 will set the word processor as WordPerfect 6, and XY4 will set the word processor as XyWrite 4.
# Word processor-specific features like on-screen text styles and 512-character font will be enabled based on this.
# ttf.blinkc: If set to true, the cursor blinks for the TTF output; setting it to false will turn the blinking off.

# shell configuration as commands: Allow entering dosbox-x.conf configuration parameters as shell commands to get and set settings.
# This is disabled by default to avoid conflicts between commands and executables.
# It is recommended to get and set dosbox-x.conf settings using the CONFIG command instead.
# Compatibility with DOSBox SVN can be improved by enabling this option.
# hma: Report through XMS that HMA exists (not necessarily available)
# ansi.sys: If set (by default), ANSI.SYS emulation is on. If clear, ANSI.SYS is not emulated and will not appear to be installed.
# NOTE: This option has no effect in PC-98 mode where MS-DOS systems integrate ANSI.SYS into the DOS kernel.
# share: Report SHARE.EXE as resident. This will allow file locking to be performed, although not all SHARE functions are emulated.
# file access tries: If a positive integer is set, DOSBox-X will try to read/write/lock files directly on mounted local drives for the specified number of times before failing on Windows systems.
# network redirector: Report DOS network redirector as resident. This will allow the host name to be returned unless the secure mode is enabled.
# Set either "ipx=true" in [ipx] section or "ne2000=true" in [ne2000] section for a full network redirector environment.
# minimum mcb free: Minimum free segment value to leave free. At startup, the DOS kernel will allocate memory
# up to this point. This can be used to deal with EXEPACK issues or DOS programs that cannot
# be loaded too low in memory. If you want more free conventional memory to be reported,
# you can for example set its value to 1.
# dosv: Enable DOS/V emulation and specify which version to emulate. This option is intended for
# use with games or software originating from Asia that use the double byte character set
# encodings and the DOS/V extensions to display Japanese, Chinese, or Korean text.
# Note that enabling DOS/V replaces 80x25 text mode (INT 10h mode 3) with a EGA/VGA graphics
# mode that emulates text mode to display the characters and may be incompatible with non-Asian
# software that assumes direct access to the text mode via segment 0xB800.
# WARNING: This option is very experimental at this time.
# Possible values: off, japanese, chinese, korean.
# ems: Enable EMS support. The default (=true) provides the best
# compatibility but certain applications may run better with
# other choices, or require EMS support to be disabled (=false)
# to work at all.
# Possible values: true, emsboard, emm386, false, 1, 0.
# umb: Enable UMB support.
# quick reboot: If set, the DOS restart call will reboot the emulated DOS (integrated DOS or guest DOS) instead of the virtual machine.
#
# ver: Set DOS version. Specify as major.minor format. A single number is treated as the major version (compatible with LFN support). Common settings are:
# auto (or unset) Pick a DOS kernel version automatically
# 3.3 MS-DOS 3.3 emulation (not tested!)
# 5.0 MS-DOS 5.0 emulation (recommended for DOS gaming)
# 6.22 MS-DOS 6.22 emulation
# 7.0 MS-DOS 7.0 (or Windows 95 pure DOS mode) emulation
# 7.1 MS-DOS 7.1 (or Windows 98 pure DOS mode) emulation
# Long filename (LFN) support will be enabled with a reported DOS version of 7.0 or higher with "lfn=auto" (default).
# Similarly, FAT32 disk images will be supported with a reported DOS version of 7.1 or higher.
#
# lfn: Enable long filename support. If set to auto (default), it is enabled if the reported DOS version is at least 7.0.
# If set to autostart, the builtin VER command won't activate/disactivate LFN support according to the reported DOS version.
# Possible values: true, false, 1, 0, auto, autostart.
# automount: Enable automatic drive mounting in Windows.
# automountall: Automatically mount all available Windows drives at start.
# mountwarning: If set, a warning will be displayed if you try to mount C:\ in Windows or / in other platforms.
# autofixwarning: If set to true or both, DOSBox-X will show messages when trying to automatically fix the "Packed file is corrupt" error.
# If set to false or none, DOSBox-X will not show such messages on the screen when the error occurred.
# If set to "a20fix" or "loadfix", DOSBox-X will show the message for the a20fix or the loadfix only.
# Possible values: true, false, 1, 0, both, a20fix, loadfix, none.
# startcmd: Allow starting Windows programs or commands to run on the Windows host including the use of START command.
# startwait: Specify whether DOSBox-X should wait for the Windows applications after they are started.
# startquiet: If set, before launching Windows applications to run on the host DOSBox-X will not show messages like "Now run it as a Windows application".
# int33: Enable INT 33H for mouse support.
# keyboardlayout: Language code of the keyboard layout (or none).
# dos clipboard device enable: If enabled, a DOS device will be added for bidirectional communications with the shared clipboard.
# Setting to "read" will only allow read access, and setting to "write" will only allow write access.
# Setting to "full" or "true" enables both; setting to "false" or "disabled" disables the access or device.
# The default device name is CLIP$, but can be changed with the "dos clipboard device name" setting below.
# dos clipboard device name: Set DOS device name (up to 8 characters) for bidirectional communications with the shared clipboard.

Have you checked that no other similar bug report(s) already exists?
What operating system(s) this bug have occurred on?
Windows 10 Pro 21H1
What version(s) of DOSBox-X have this bug?
0.83.19 and 0.83.11 SDL2 Visual Studio 64 bit
Describe the bug
If you configure the game in SVGA mode using SETUP.EXE in the SCREAMER directory and launch it, it works correctly the first time by typing SCREAMER at the DOS prompt.
But if you close the game and try to launch it again, the game does not start anymore:
By the way, the old DOSBox 0.83.11 SDL2 Visual Studio 64 bit even closes immediately. I tried to open the logging console and there are some messages about "ERROR BIOS:INT15:Unknown call" and "ERROR MOUSE:Unhandled videomode 69 on reset". If the game is configured in VGA mode it can be closed and relaunched as many times as you want without closing the emulator. Could the bug be related to this discussion https://stackoverflow.com/questions/43194265/dosbox-is-buggy-with-int-15h-ah-86h ?
Expected behavior
The game should always restart regardless of the graphics mode.
Steps to reproduce the behaviour
1) Configure the game in SVGA mode with SCREAMER\SETUP.EXE 2) Launch the game and play a little 3) Exit from the game 4) Try re-launching the program by typing SCREAMER at the DOS prompt.
