Getting an emulator to auto-run a rom?

[Yukima]

Okay... I'm going to risk sounding like absolute gibberish, but whatever...

If I have an emulator such as one for NES, SNES or Genesis, and I have a single rom, is it possible to get that emulator to run the rom automatically when it starts up, without going through the GUI first and loading it manually?

I'm asking because I've been playing around with homebrew and emulators on the Gamecube lately, and I want to see if I can just have an emulator and a rom burned on a disc, put the disc in a modded Gamecube, and have the game run on the Gamecube just as it would have on the original system it was for. That would be a cool thing if it was possible! (though logically speaking it'd be a waste of a DVD with just an emulator and one game on it But I don't care!) There are a couple of games I want to do this for, just for kicks.

Most emus accept comands so you could make bat files to run them.

C:\epsxe140\epsxe.exe -loadiso e:\we2000\we2000c.iso

once you have your command use notepad and save as .bat

Hmm... that post looks promising - but how would I go about getting the commands to work on a Gamecube, and have it make a rom auto-run off of a disc? I tried googling for this and got nothing, apparently no one else has ever done this...

You would have to figure out if the emulators in question support command line options, and if the GC loader allows you to pass options. It's certainly possible. Worst case scenario you'd have to compile your own build of an emulator that automatically launches the ROM you want. SNES9x-GX and FCEU-GX are both open source, you can compile a .dol with devkitpro, and it's fairly easy to build a bootable GC disk with free tools. So yes, it's possible but not straightforward, and would probably require peeking at some source code.

Well I know this has been done with Neo Geo CD games emulated on the Dreamcast, though I'm not sure exactly how it works. You might try asking on the snesorama boards, this seems like something right up their alley. Maybe there's a roll-your-own kit for this kind of thing, that'd be pretty cool.

The closest i can think of is if you just have one rom in the roms folder for NesterDC it should automatically run it. I even recall seeing downloadable cover art for that purpose.
