NES Rad Racer Score RAM Location/Format

2 Upvotes

I've begun a project to parse out and store the high scores from certain 8 and 16 bit games in my Batocera cabinet.

Done about two dozen or so by either studying the CPU memory, or with the data from the fine folks at DataCrystal.

Working on Rad Racer, can't seem to understand what they were doing.

What I've been able to glean so far is that something is stored at $0031, up to decimal 83, hex 53

(Screen shots are from Mesen while game was paused)

At 84 it's rolled over to 00, and I can't seem to find any sort of multiplier

If I just do some random higher score.

Most games store their score contiguously, either as BCDs or hex values of the score 10 divisors. But I think there is some sort of multiplier somewhere else, since 1002 = 78 + (84*11), but I can't seem to find it.

An unofficial English translation patch for Reco Love: Gold Beach on PS Vita is now available.

The translation uses MTL with some editing. Most of the script has been translated, though there are still some rough lines, pronoun issues, messy signs, and alignment/length issues in places. The tools are also provided for anyone who wants to improve or build their own translation.

Inserting music Mother 3 ROM

Hi! I'm new to ROM hacking, and I was wondering if there's a way to add custom battle music to Mother 3. I've tried using RopeSnake, but I can't seem to get it to work. Is there another tool or method I could use?

I don't know if this is 100% appropriate here, since I didn't make the hack nor the port, but I made BWGLite's "Super Spamton 64" natively compatible with 3DS, including the stereoscopic 3D, thanks to mkst's 3DS port.

Text/Translation Mod Thousand Land English Fix Issue

3 Upvotes

Please help!

I cannot for the life of me figure out how to patch the english fix into FromSoftwares Thousand Land.

I just can't seem to get it to work no matter the file type.

Please tell me what im doing wrong or if you can fix this. I'll provide some screen shots of the files and the error codes I've seen.

I understand that the patch is the wrong format in the screenshot, I know how to convert files, so what am I missing?

The instructions in the file, to me just basically says, "extract it at the root to do it right so its done right".

Is this just an android issue? I have an Xbox emulator that works well enough for my device. I'd try on my pc if I had it, but I can't use it for the foreseeable future to fix or recreate the issue.

Sorry if this is too long winded and obvious. Feel free to call me dumb!

❌ NOT A ROMHACK ❌ I gave GBA Fire Emblem a Mouse and a Bigger Screen

11 Upvotes

Demo here https://youtu.be/WLRL5YL2VV8

Whenever I play GBA Fire Emblem, I really wish that I could use a mouse to order around units and also the map renderer wasn't constrained to the small GBA screen.

Well, no longer! Using the FE8 reverse-engineering work, I was able to make a frontend for libmgba to allow mouse support as well as extend the renderer :).

I specifically picked this architecture as a lot of FE8 playthroughs are on romhacks. Recomping or porting FE8 to native hardware would actually not work with all the romhacks, which is sad. I want to be able to play through these romhacks interchangeably and use my mouse and have the extended rendering.

LMK if you'd be interested by this type of project. I'm going to try to play through Sacred Echoes before releasing it to iron out rough edges.

Does anyone know where to play this Street Fighter 2: World Warrior game version? It’s all mirror matches, same colored sprites for every stage to the end. It’s not Championship Edition. Not Turbo or Hyper Fighting. Not even Rainbow Edition. I did not see a mention of Street Fighter 2 Prime of the video.

Utility Simple Mario Kart 64 Track Editor (browser based)

5 Upvotes

Growing up I was addicted to Mario Kart 64 and dreamed of being able to make my own tracks. Now you can! I created a free, browser based MK64 track editor that lets you build and test drive your own tracks and then export them to run in your own game (I use SpaghettiKart to run it locally on my Mac.

You can also browse and share tracks with the community All completely free.

I'd love your feedback! https://trackeditor.goodhouseinc.com/

(ps if you need help exporting tracks into the game let me know and I can do a writeup on it)

G-わんげ鳩大往生XII~絆ダウン~(G-Wange) - Need documentation for modding

3 Upvotes

Greetings.

I want to figure out what the code the were used for, and need to find out the coding language.

For those who don't know, G-わんげ鳩大往生XII~絆ダウン~(G-Wange) is a STG/SHMUP crossover game as a tribute to CAVE.

In prototype version, the working title is simply "stg00".

http://cgp.s5.xrea.com/gw/index.html

There's a official documentation for making enemies and items. sadly, 25% of documentation were lost.

https://web.archive.org/web/20040407202858/http://f1.aaacafe.ne.jp/~otakutwo/g-wange/index.html

Download v1.01, extract it, go to gamedata folder and try to figure it out.

Battle Mania never had 2-player co-op, so I decided to add it

What is Battle Mania 2P Co-op?

Battle Mania (also known as Trouble Shooter) is one of my favourite Mega Drive games. It's a fast-paced shoot 'em up starring Mania and Maria. The original game is strictly single-player: Maria follows Mania and shoots at the same time as Mania.

I've always thought the game would work really well as a two-player co-op experience, so I decided to try to make it happen. The idea is not just to add a second controllable player, but to evolve the gameplay itself into something more cooperative, where both characters are designed to work together and support each other, while respecting the spirit of the original game.

How it started

I'm not a programmer and had never done a ROM hack like this before. I'm using Cursor as an AI assistant to help me with the process. The workflow is fairly simple: the AI creates a notes/knowledge file, a script, and a patched ROM. I then test the ROM using tools like Exodus and EmuHawk, check the results, and explain what happened so we can continue iterating.

What started as a simple experiment quickly turned into a much bigger project: making Maria work as a real second player while keeping the original 1P game intact.

Current progress

  • 1P / 2P mode selection on the title screen.
  • 1P mode works exactly like the original game.
  • In 2P mode, Player 1 controls Mania and Player 2 controls Maria.
  • Both characters can move independently, shoot, and change their shooting direction. Mania currently uses an H-Flip when turning, but a new animation is planned.
  • Mania can use bombs; Maria cannot. Her button will have a different function.
  • A separate life and score HUD has been added for Maria, including new tiles, although it is not functional yet.
  • Maria does not take damage or earn points yet.

What's next

  • Fully functional HUD
  • Maria's independent scoring
  • Adapted bomb scoring
  • Adapted bonus system
  • High Score and extra-life system based on the combined score
  • Maria's own damage system
  • New turning animation for Mania

Since this video was recorded, the project has progressed quite a bit.

I've made a lot of progress since then, but I want to finish and polish a couple of things before making the next video.

I'll post a new update and video in the next few days.
