我用dosbox-x挂载WIN98，有些游戏不能全屏，一运行就变成窗口化
用的dosbox-x 64位的，2025年1月1日版本
比如龙战士4.热血江湖，新天使帝国等，，一运行就变成窗口化
求大佬指教如何让它们固定全屏运行

fullscreen = true
fulldouble = false
fullresolution = 1920x1080
windowresolution = 1152x864
windowposition =
display = 0
output = direct3d
videodriver =
transparency = 0
maximize = false
autolock = true
autolock_feedback = beep
middle_unlock = manual
clip_mouse_button = right
clip_key_modifier = shift
clip_paste_bios = default
clip_paste_speed = 30
sensitivity = 100
usesystemcursor = false
mouse_emulation = locked
mouse_wheel_key = -1
waitonerror = true
priority = higher,normal
mapperfile = mapper-dosbox-x.map
mapperfile_sdl1 =
mapperfile_sdl2 =
forcesquarecorner = true
usescancodes = auto
overscan = 0
titlebar =
showbasic = true
showdetails = false
showmenu = true

为什么我用虚拟机运行WIN98玩不了《家园1》？
