Making a DOS boot disc

I am running Windows XP, and I am trying to make a MS-DOS boot disk. I dl'ed the boot program from www.bootdisc.com (dos 6.22), than i ran it and it gave me only 50 kb of space to fit a NES emulator and a ROM into! how do I get more space?

The thing with floppy disks is that there isn't a lot you can do to get more space on them. You could compress the disk I suppose, but that would be about all. If you zip the files, they will no longer be bootable. If space is an issue, I suggest making a bootable CD-ROM.

Look on the disk and see if there are any unneccessary files. The only ones you should need are COMMAND.COM, IO.SYS, and MS-DOS.SYS. You could also put AUTOEXEC.BAT if you want it to start your emu automatically.

Most of the system files will be hidden. Windows probably will not show them. If the disk boots, then the files are on there. The only visable files will be the command.com, Autoexec.bat, and config.sys. These are the only visable files you need on the disk in order to boot, the rest are hidden. As goodie mentioned, it might be a good idea to put the command line of the emulator you are using in your autoexec.bat. Use notepad to do this. It should look something like this:

@ECHO OFF

A:\<your emulator's executable file>

Then save the file. If you do this, the emulator will run automatically when you use the boot disk.

I just removed QBasic, there was then enough space for Contra and LoopyNES

Yeah, but which version?

The Beta or v 0.51?

Always go with the newest stable release. (v.5x)

Try searching Google for "dos nes emulatuor command line". I got one that takes less than 50k that way.

Well, v0.51 keeps giving me an error when I load it to a boot disk. The beta loads, but the "Load" button doesn't read the floppy, so I can't get my games to run.

I think it looks on the hard drive for the ROM, not the floppy. I wish someone could fix this...

heres how I did it:

AUTOEXEC.BAT:
nes.exe 1.nes

1.nes = Super Mario Brothers Rom

Worked fine on my DOS 5.0 PC

well...say I have more than 1 ROM. Is there a way to load the emu, then select which ROM I want?

Not so sure, maybe you could do that by putting a choice menu in AUTOEXEC.BAT
