[NINTENDO64] About Super Robot War 64

[kikeroga]

Hey, everybody!

I want to hack this game and I'm looking for binary analysis information.
If you have found or figured something out, I would like you to write it in this thread.



Thank you.

p.s.
Sorry if the writing destination is wrong.

I guess you are welcome to make a thread but how much traction you will get I don't know -- most people only care about Super Robot Wars/Super Robot Taisen if is on the GBA or PS1, where we get many people wanting translations/as it appeared in Japan versions* (fewer doing anything about it), and I don't think I have ever seen someone ask about the N64 version, to say nothing of there generally being a dearth of N64 hackers (it is an annoying console to work with and a bit of a flop too, to say nothing of generally having aged like milk).

*part of the reason it never appeared outside Japan much was rights to all the various robot manga/anime were not with the same holders which makes it a nightmare. What then appeared outside it sometimes lost things, or never had them to begin with.

If you want to start out something simple then maybe make some cheats and share them with others -- those looking into the game then don't have to make such things themselves and thus can explore the systems without having to worry about dying/ammo/energy (possibly money if this is one that upgrades parts like that), and can indeed also allow you to see different things.

Hi FAST6191-san,

Thank you for your reply and advice.
I am also analyzing this game now, so if I find something, I would like to write it here.

Thank you.

I have no hacking or translation skills, but I do hope whatever you find does eventually help lead to a fan translations of SRW 64 being made 

[kikeroga]

Hi BassForever-san,

This SRW is a fascinating scenario, so I hope it too.
Currently, I am working on analysis while making tools, so I will do my best.
It's just a small hack, but I plan to release the first version soon.

Thank you.

[Dashman]

I for one would love to see a translation of 64 happening, more even than one for R or even D. The scenario branching makes it really interesting, despite its flaws.

Once you have some progress, I'd recommend you check your notes with Zoinkity, since he started checking the game some years ago. Please note that his comments on how the text is accessed in the game were along the lines of "whoever designed this should be shot".

SRW64 hack, I hope you get excited.

Thank you.

I understand your tool encodes SJIS text to hex code that can be recognized by the game, am I right? And the tool even has conversion sets for several other games, that's pretty neat

I've noticed many western characters don't seem to be mapped yet: https://mega.nz/file/28tmXKRA#iatD28DXPLkJ5mDxI7ibGo4liDuVl6Q6vmy0FNrhCx0

Maybe it's because the order of these characters in the font is a bit weird, hopefully this helps: https://mega.nz/file/eh8mWSbS#4ZbIX0MbrwXuWMiUnGgDpx_uigvm3lgvIDj9MsQYIxU

Before you ask, I didn't extract the image and have no means to extract or insert content from / into the game. I understand the rom is compressed in LZSS, but if you already got to the point of mapping hex to characters you don't need me to tell you.

If you manage to extract files, I'd love to take a look at the animation mapping files. Seeing how characters like Master Asia are animated means it should be possible to add animation to any unit in the game (with a ton of effort).

[kikeroga]

Hi Dashman-san,

This is helpful. Thanks to you, I will be able to create a complete conversion configuration file in the near future.

I don't know anything about image extraction so this is very helpful.

Thank you very much!

Hi kikeroga,

I'm unable to paste hex code taken from the editor (using MadEdit) into your tool (it always pastes the text version). Not sure if you're copying the hex code by hand or there's a trick to it that I'm unaware of. So far I've copied everything by hand, which is less than ideal.

I ran a little test based on your screenshots and I think it's pretty safe to say that scenario / battle text can be found with relative ease by searching for characters DC 00 and DD 00:
https://mega.nz/file/zgtwRCzC#PxaoDrNpIk4bUZJiPLuYsGfXCLfXSy2Cgs_tDdxvPxs

Although looking at other lines, I'm inclined to say these characters should be 00 DC and 00 DD.

This is really asking for a tool, but at the moment I'm busy with another project and can't really help much here

Here's hoping this thread piques someone's interest in the game.

[kikeroga]

Thanks for your comment, Dashman-san.
I use a binary editor "Stirling".

Take it easy. Chao!

Below is the cheat information.
You can increase the number of participating units by using hidden scenarios that you cannot normally play.

- Procedure for playing hidden scenarios -
1. Put the following scenario number in yy of cheat "8010F5F0 00yy" and cheat on

Hidden scenario No.
6D:F91 take-off
6E:F91 take-off
6F:GoShogun take-off!
70:GoShogun take-off!
71:Zambot 3 appeared!
72:Zambot 3 appeared!
79:New comrade

2. Save to ROM cartridge with in-game intermission, cheat off and reset game
3. Load the saved data and go to the next map to start the yy scenario
(* When the scenario is over, it will return to the original scenario flow.)
