is there a way to convert roms from pal to ntsc?

Hi,

does somebody know hot to fix the Iraq War 2003 rom to get it working on real hardware?
The line 01F0 is used for something else. Can`t find any GG Code for this Game.
Burning the file with my eprom burner (without any change, exept swap files) does not work on my real harware.

It's difficult to figure out problems with ROMs on real hardware, especially when the ROM works fine on emulators. I tried it on Gens and Kega Fusion and had no problems.

It appears as though the game doesn't care which region it's played on, so I don't think that's an issue.

It also appears that the game doesn't do a checksum check, so making changes to the ROM shouldn't matter.

Since the game runs fine for me, I'm working blind here, but I've got a few codes you can try. You can probably try all the codes at the same time and see if it works. To be honest, chances are the codes won't work, but it's worth a shot.

Make all those changes to the ROM (or convert them to Game Genie codes) and see what happens. A few of those codes are just bypassing subroutines at the very beginning of the game. Those subroutines may or may not be doing some kind of check that your hardware fails. Another code makes it so that some kind of Z80 bus request check will never fail.

If they don't work, there's not much more I can do to help. Maybe someone else with more knowledge of the Genesis hardware can figure something out.
