After completing TNZS on MAME again and hex editing the lineup on Neogeo Cup '98 to feature the real names, I'd thought I would have a poke around with the TNZS story ROM to see if I couldn't make it do some fun things. I'm loathe to use the words 'ROM hack' but that's basically what I want to do. I started off with something semi-simple with a good tutorial here: http://www.paladingrp.com/brianb/rom_hacks/ikari.html I've managed to figure out the ROM checking code on TNZS and got that disabled, so I can now edit it but I'm having trouble doing the freeplay option. I've narrowed down where credits are in memory but due to the tutorial only covering a 1 CPU setup it's making my brain go a bit melty trying to figure out how the 2 x Z80's and I8742 mcu interact with each other. Seeing as this place is called Assembler Games I'd thought I'd try here, but it seems to be more about consoles than arcade systems. Can anyone recommend somewhere that would be more fitting? AO perhaps?
