Hello if anyone is an Ikari warriors fan out there, I just made a free play ROM hack since I could not find one already out there. I thought I would share it with anyone who might want it.
This is my first real "useful" ROM hack right now it's only been tested in MAME, but it's pretty darn simple and should not effect game play at all as the only instructions added are immediately after the system startup test, the other hacks are in place operand changes to the original code that do not add or subtract any CPU cycles.
it's for the mame rom "ikari" which is supposed to be the JAMMA ikari version. It replaces rom.1 as labeled in the MAME zip file.
I have not looked at the non-jamma version yet. But that's next as I think my physical ikari game is a non-jamma boardset and the point is to update my game ROM so I don't have to "coin up".
if your interested you can get the hacked ROM at
http://www.paladingrp.com/brianb/rom_hacks/roms/ikari-free-play/1.rom
I will also be documenting step by step how I did the hack for anyone who's interested. I hoping to make it so people who have never did a ROM hack and want to learn how can follow along to learn how to do one step by step.
When finished the guide will be at
http://www.paladingrp.com/brianb/rom_hacks/ikari.html
Theres a page there now with my scattered notes that I took while doing it, but it's not really readable nor consistent as I changed my methodology while writing the hack.
have fun
