is there a DOS command for running a program with windows 98 compatibility?
example
start "" /win98 "resident evil 2.EXE"

start "" /win98 of course, i made this line up, but it was an idea

PC version "resident evil 2.EXE" has NO known emulators, so i must use windows 98 compatibility mode to get some stabilities.

Traditionally you right-click the application, go to Properties, go to the Compatibility tab, and pick the version you want compatibility with.

Windows 11 doesn't let you go older than Vista, so you may want to check out https://pcem-emulator.co.uk/ instead.

test-1.bat

Code: Select all

@echo off
set "AppName=C:\Program Files\WinRAR\WinRAR.exe"
set "CompLayer=WIN98"
reg add "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%AppName%" /t REG_SZ /d "%CompLayer%" /f

>go to Properties, go to the Compatibility tab,
not this manual way, everytime i meet the problem, it is not just only OS dependent but also fresh installation DEPENDENT, i never wanna go to that path. i removed every LNK file from games, some utilities, nircmdc and etc, i keep only everlasting, almost OS INDEPENDENT batch files that i can make them work on laptop, pc, all different resolutions, doxbox-x, scummVM. any OS's
i also removed or replaced windows shell extensions with ztree's batch shells, so windows explorer doesnt run anything in my pc's except for the default shells that can be auto-rebuilt themselves, i am a happy anti windows user, and DOS commands make me feel smarter

i found this line in website set __COMPAT_LAYER=WIN98, but i dont know how to use it

>Windows 11 doesn't let you go older than Vista
i dont have win11 yet, i have win8 and 10. there is probably a way to run old programs in win11 as much the same as win 8 and 10.
win 8 and 10 are the same, except win10 now forces uninstallable anti virus and slows down my laptop by 300% ~ 2000%, it always checks programs in my batches to the point of halt.
win8 and win10 also dont naturally run almost anything below vista, but emulators like CnC, dgVoodoo, nGlide, wine, scummVM made them run super nicely

while i was posting, a new thread came in, i will try this, registry editing needed and no simple command line
reg add "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%AppName%" /t REG_SZ

thanks

That's the entire command; there's nothing else.

Code: Select all

@echo off
SET "A1=%~dp0"
set "AppName1=%A1%CLAIREP.EXE"
set "AppName2=%A1%LEONP.EXE"
set "CompLayer=WIN98"

reg add "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%AppName1%" /t REG_SZ /d "%CompLayer%" /f
reg add "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%AppName2%" /t REG_SZ /d "%CompLayer%" /f
thanks this will do, made it pathname independent. normally i dont want to go with registry either, this is how i run games
1. install
2. export registries
3. backup
4. uninstall
5. run the backup with a proper registry reinput

example
delete all other 100s junk keys and leave only whats essential AND make it drive and directory name independent
change
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Monolith Productions\No One Lives Forever\1.0]
"WorkingDirectory"="w:\\@OK games\\NO ONE LIVES FOREVER 1\\"
to
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Monolith Productions\No One Lives Forever\1.0]
"WorkingDirectory"="."


my last question on how to delete registry but i didnt find one in website that i need
[HKEY_CURRENT_USER\SomeKey]
"SomeStringValue"="Hello"

[-HKEY_CURRENT_USER\SomeKey]

[HKEY_CURRENT_USER\SomeKey]
"SomeStringValue"=-

what would be the way to delete all values except for the key's name in this case the key name is somekey( which would be "Layers" later)
because AppCompatFlags\Layers : CLAIREP.EXE was in many registries, it spreads to the point deleting it often is not too plausible anymore
HKCR HKEY_CLASSES_ROOT
HKCU HKEY_CURRENT_USER
HKLM HKEY_LOCAL_MACHINE
HKU HKEY_USERS
HKCC HKEY_CURRENT_CONFIG

my random trials were, and didnt work
[HKEY_CURRENT_USER\SomeKey]
""=-
[HKEY_CURRENT_USER\SomeKey]
{}=-
[HKEY_CURRENT_USER\SomeKey]
=-

Code: Select all

set "CompLayer=WIN98"
what would be the CompLayer value for WinXP and Window 8.1 and maybe for vista and windows 7?

maybe any of the below things?
"CompLayer=WINXP"
"CompLayer=WINDOWS XP"
"CompLayer=XP"
"CompLayer=XPSP3"
"CompLayer=WIDOWS8"
"CompLayer=WIN8"

websites didnt have much about CompLayer information
Alien Shooter 2 - Zombie Shooter 2 MOD worked well in Win8.1and XP but not in a Win10 computer.
i also made and tested a shortcut of "ZombieShooter2.exe" with the compatibility mode of windows xp and win 8 and etc, but the compatibility tests didnt work well in win10, and no known emulator, but i hope and want to get it to work with a batch file someday

Even if you don't find anything about it in the internet, it'd be so easy to figure it out. You know where the values are saved in the registry. So, just change the compatibility in the context menu of the executable and observe the updated registry value. Press F5 to reload the regedit interface.

there was no search result for the string "CompLayer" in regedit
but ZombieShooter2.exe had the results as below
~ WIN98
~ WINXPSP3
~ VISTARTM
~ VISTASP2
~ WIN7RTM
~ WIN8RTM
i just removed ~ for CompLayer=

it worked, thanks

There's actually now a simple way to run any real DOS command.com in 64-bits Windows 10/11, including Windows 98's DOS 7.1 if you wish.
This allows testing batch files intended for Windows 98... Provided that they use only text-mode features, no graphics.

For that, download the msdos.exe DOS kernel emulator from: http://takeda-toshiya.my.coocan.jp/msdos/index.html
Think of this emulator as a kind of Docker engine for DOS applications.

Then install the DOS 7 executables in a directory. Ex:

Code: Select all

C:\JFL\Temp>dir \JFL\Tools\dos7
 Le volume dans le lecteur C n’a pas de nom.
 Le numéro de série du volume est B4F9-E8AF

Then create a launch script called DOS7.bat:

Code: Select all

@echo off
setlocal EnableExtensions EnableDelayedExpansion

set "SCRIPT=%~nx0"				&:# Script name
set "SPATH=%~dp0" & set "SPATH=!SPATH:~0,-1!"	&:# Script path, without the trailing \
set "OS=DOS7"

path %SPATH%\%OS%;%SPATH%\DOS;%SPATH%

set "CMD=%*"
if not defined CMD set "CMD=%SPATH%\%OS%\command.com /K prompt [%OS%] $P$G"

:# Use msdos.exe from http://takeda-toshiya.my.coocan.jp/msdos/index.html
%SPATH%\WIN64\msdos.exe %CMD%
You can then use that script to start an interactive command.com prompt, or run a DOS command directly:

Code: Select all

C:\JFL\Temp>dos7

[DOS7] C:\JFL\Temp>truename %COMSPEC%

C:\COMMAND.COM

[DOS7] C:\JFL\Temp>exit

C:\JFL\Temp>dos7 C:\JFL\Tools\DOS\dirc.exe -V
3.8.1 2022-10-19 DOS ; MsvcLibX 2023-01-03 ; SysLib 2023-01-09

C:\JFL\Temp>
I've also installed FreeDOS executables in another directory, and created a FreeDOS.bat script similar to the one above. Both DOS7 and FreeDOS work with very similar results.

isnt compatibility layer set by __COMPAT_LAYER variable? -> https://stackoverflow.com/questions/378 ... ctually-do . Though this not work so well ... Can be set also through a shortcut settings.
