Just something I came up with last night and decided to make the concept a reality.

Since DosBox allows command-line based changing of emulation parameters, this little batchfile (I know, I suck at programming <_< ) allows the user to change the EMS/XMS/UMB settings easily. :ok:

Nice one.
You might want to take a look at the db-info.bat created here
http://vogons.zetafleet.com/viewtopic.php?t=14601

It shows some power of the config utility. (things you probably didn't know)

And it has also shown me how I can do certain things better than I did them in this one.

Thanks!!! :ok:

I was thinking how to code a more extensive config utility without having to do it the way I did this one (grossly inefficient code).

Guess I know what I'll be doing this evening :D

it seems the script got even more advanced

Better use input parameters, it's more agile. For example, EMS.BAT:

Code:

@echo off



if %1=="true"**goto true

if %1=="TRUE"**goto true

if %1=="on"****goto true

if %1=="ON"****goto true



if %1=="false" goto false

if %1=="FALSE" goto false

if %1=="off"** goto false

if %1=="OFF"** goto false



config -get "dos ems"

echo.

echo.

goto end



:true

config -set "dos ems=true"

goto end



:false

config -set "dos ems=false"



:end

It sets the EMS emulation as you tell it, or alternatively tells you its status if you type no parameters. There are four ifs for each instance only to make it more user-friendly, you get the idea. This gave me the idea about one that tells you the cycles --in case you're fullscreen-- or alternatively sets them. The second part is easy, although it would be only as foolproof as the CONFIG command itself --in case the user types letters or nothing instead of numbers the cycles are set to 2500:

Code:

@config -set "cpu cycles=%1"

But as far as I know you can't tell a BAT file to do something in case the user has *not* typed a given parameter. :(

I like he idea, but I see there is room for improvement.
I don't know if it's too difficult to check in advance what all the settings are instead of enabling them all.

Maybe it is an idea to use a real programming language like C, because you can use more functions and control structures.

Keep up the good work.

I've been trying to do that, but it turned out a bit more difficult than it seemed at first. Still trying, though. :)

It's an idea, except I know less about programming in C than I do about voodoo magic. :P Maybe one day...

To check the settings in advance use the same structure as what Data linked:

Code:

config -get "dos ems" > nul

if %CONFIG%=="true"**...

if %CONFIG%=="false" ...

Replace the "..." with commands, a goto one if you want more than one command to be executed for each option. You wouldn't need the %CONFIG% variable to be created if the CONFIG command returned errorlevels, but it always returns 0. But still command prompt input is faster than menus. I won't start with C code, I'm not that bored right now. :P

I don't think you can configure Dosbox with Voodoo magic. :D
Maybe when I'm really bored then I'll try a version in C or maybe in Quickbasic, but right now I think I already have enough unfinished projects going.

Good luck with your project.

Nice one the_fifth_horseman. I like it as I can use it to do stuff I never knew DOS box could do.
