Just wanted to let everyone know that RetroNintendoNerd did send me a savefile. Unfortunately, it was right before the end of the first stage, not the end of the game. However, I got lucky and figured out how to manipulate the savefile into thinking it's on the last stage.

The game did load the complete state from stage 1 but was thinking
it's on stage 8. So killing one easy enemy was enough to trigger the credits. Gundam also stores each savestate 3 times so it can heal corrupted states. Good idea actually.

I still have to figure out how to change the credits though. It's a bit more complicated since I can't use realityboy or the planetvb emulator to load the savefile. Well, next weekend I guess.

Gundam Savestates Needed

Hey Everyone,

I'm working on a complete translation patch for Gundam and noticed that the credits are not translated. Would someone be willing to play the game in mednafen up to the point where it almost ends and make a savestate? Best case would be to have a statesate right before the credits, so that I can load up the state, press a button and jump right to the credits.

I will send you the ROM a week early and add you to my list of cool people.

I mostly use 3 emulators:
1. Reality Boy with the debug features enabled. It allows you to look at the charmem, bgmaps and so in a very convenient way.
2. Medanfen. The build in debugger allows you to read the asm rather easily and you can do stuff like changing the memory during runtime.
3 planetvb emulator. It has a very good breakpoint system and allows you to see bgmaps and so on as well. On top it will show you addresses for everything which is really handy. With a little work this could become the only emulator you would need.

There are a few other tools like David Tucker's disassembler and Horvats MV810ASM but I rarely use them.

I often use the VB tech scroll (https://www.planetvb.com/content/downloads/documents/stsvb.html), as a reference. It pretty much contains all the information that has been collected from several sources over the lifetime of this community.

What I usually do is reverse engineering a game using the emulators I mentioned above. I write down my findings and then write specific tools for each game. I'm in the middle of writing a tool that can replace images in many virtual boy games (so far I have Innsmouth, Space Invaders, Gundam and Faceball). However, it is very hardcoded right now and could not be used without changing the actual code.

You can hit me up in discord if you have any questions. You can also see what I'm talking about if you look into the thunderstruck-projects channel on the planetvb discord.

If I understand correctly, with this latest design update, we can use the buttons on the cart to switch between games. Is that it?

If so, I am sold. I was holding out for the MultiBoy32, but if this will let me switch between ROMS without needing to plug the cart into a computer, I'm sold.

Also, if we don't need to plug the unit into a computer and the ROMs are stored on an SD card, what is the purpose of the USB connection?


You need USB for power. You canít flash it while plugged into the VB.

Iím open to suggestions for powering the cart when out of the VB.


I would most likely just buy a mini powerbank. They do exist with iphone connectors: https://www.amazon.de/KOBWA-Magnetisch ... ackup-Akku/dp/B07MJG8X58/

Hey everyone,

I remember that one of the translation patches would translate the game but not the credits. I can't remember which game that was though. Does anybody know?

A mednafen savestate would be great as well.

Hey Everyone,

I created an English translation patch for Space Invaders. It wasn't this straight forward this time, due to the way the game stores images. However, I managed to write a tool that can replace the Japanese (and many other) images in the game.

Attached you will find the translated ROM (padded for you convenience), some screenshots and my notes.

You can find a video here: https://youtu.be/ctwI9xXrSS8

I'm planning to do more smaller projects soon, so stay tuned.

If you want to support me, you can do that here: https://www.patreon.com/thunderstruckProjects

Just don't be disappointed when you send money and I disappear. I live a rather busy life.

Have fun

Looks cool. Wanna trade? I send you 5 of mine and you send me 5 of yours?

Sorry it wasn't clear in the original post. To get it to work, you have to press, AND HOLD, the following buttons:

LEFT (on right D-pad) + RIGHT (on left D-pad) + SELECT + A + R + L

Thus, you can use your left thumb to press and keep pressing the RIGHT button on the left D-pad as well as the SELECT button, and you can use your right thumb to press and keep pressing the the LEFT button on the right D-pad as well as the A button, and you can use your left and right pointer fingers to press and hold the L and R buttons. If you are pressing and holding all of these buttons down at the same time, the code should work, and I don't think it matters which buttons you start to press and hold down first.


Gotcha, I was super confused too, reminded me of trying codes for Street Fighter Alpha 3, that was rough, thanks for the response though, didn't expect that. :)


Also make sure you don't have the keys mapped to close to each other on the keyboard. Windows will start ignoring keys because it thinks you are smashing your face at the keyboard.
