SNES Genghis Khan 2

[kevinroland]

Hello,

Thank you for taking the time to read this. I've always wanted to make some modifications to this game. I read the newbie starting guides and FAQs. I googled "Genghis Khan 2 rom hacks" and various versions of the phrase, and searched these boards, and as best as I could find there aren't any existing ROM hacks for the game or any game-specific utilities.

So, before I jump right in, I hope to avoid some trial and error time sinks. There are multiple utilities for multiple types of editing, and since this is my first time I don't know any of them or their pros/cons for various tasks.

If you're unfamiliar with the game, a brief description:
Turn based strategy. The game is a map of asia/europe, divided into provinces. Some of the provinces are playable (mongolia, japan, england, etc.). You develope your province, build an army, and conquer enemy provinces.

This is what I'd like to accomplish (eventually, I'm pretty sure it's going to take a lot of time especially since I have zero experience).
*Currently only a few of the provinces can be played by the Player, I'd like additional provinces available to be selected and played.
*Change various elements to make the game harder, including things like changing enemy starting resources, changing enemy ruler stats, disabling negative events (like rebellions or plagues) for enemies.
*Game currently supports 2 players, but would like the option for both players to play the same empire (player1 is king, player2 controls his particular province in the kingdom)
*Change various army units, like the firing range of catapults, and change the value that the computer associates with them (ie: computer currently buys a lot of cannons, for example, which are terrible units).

I'm fairly certain this is not a "newbie" project. But I really like the game and this is something I've always hoped someone would do. If the right tools exist, then I should at least try and do it myself.

If you have any suggested utilities to best accomplish this, or any extra reading that would help, I'd love to see it. Advice and tips always welcome.

Thank you,

Hi Kevin, I just submitted a NES - SNES search/patch tool to RHDN that lets you enter a RAM address and it will search your ROM and see if it can find places where your RAM address changes things in the game.  If it finds any matches/ROM addresses, you can make changes to values for some of the things you're looking for like: enemy starting resources, changing enemy ruler stats, etc.  Once you've made any changes, you can then patch them into your ROM.  I have not tested it with your game, so no guarantees that it will work.

There are over 150 existing RAM addresses for that game:
https://gamehacking.org/game/43034
https://gamefaqs.gamespot.com/snes/588353-genghis-khan-ii-clan-of-the-gray-wolf/faqs/46485

If you don't see the particular RAM address you're looking for, it's fairly easy to make your own with SNES emulators like Snes9x, Zsnes, etc that have built-in RAM searching abilities.

The NES - SNES tool also has a section that will try and find a RAM address for you if you can't find one.  It's pretty basic, but it might find what you're looking for.  If it finds a RAM address for you, you can then use that new RAM address and see if it can find a ROM address.

Just to be clear, the new tool may not find matches/ROM addresses for every RAM address, but it's certainly worth trying out.

Thank you,

Thanks for sharing the NES - SNES search/patch tool with me, [kevinroland]. I'll definitely check it out and see if it can help me achieve the modifications I want for Genghis Khan 2. I appreciate your insights on using SNES emulators for building RAM addresses too. Do you have any other tools or resources you recommend for ROM hacking? I'm always on the lookout for helpful tips and tricks. Thanks again

I personally use Geiger's Snes9x Debugger for most SNES hacking.  It does a good job of RAM searching, and is very good at finding where RAM addresses get changed within the ROM.  RAM searching and hacking is relatively easy, ROM hacking is a bit more involved.  Probably best to start out with just RAM stuff, then move on to ROM hacking later.
