SD 2 Gundam with a redump

LuigiBlood here, bringing now a redump of SD Gundam G-Next’s GNEXT MAP DATA with a different date: 2/25.

This redump was done by techknight! However if I was just going to bring this dump and that would be it, that wouldn’t be fun isn’t it?

Because there’s little to no instructions on how to actually make use of this extra content for SD Gundam G-NEXT, it gets really confusing and fast, I have done my research.

First of all, load SD Gundam G-NEXT with the Memory Pack with this extra content with the emulator of your choice. The game will absolutely NOT tell you the data has been loaded, making it extra confusing to figure out.

In the main menu, there’s a Scenario mode, a Campaign mode, and what’s called ConfigMap mode. The Satellaview content can only be accessible via the ConfigMap mode where you can set up a custom single player or multi player match with the map and units of your choice, so select that mode.

You can now select maps, and you will need to select three types of maps: a Earth map, a Space map, and a Moon map. All three types are required to start.
The main game contains 7 maps of each type, the extra content brings 3 new Earth maps and 3 new Space maps, here’s a list of them:


Once you selected one of each type, press Start, you will now see the Rule Configuration screen.

The rule config is comprised of 3 pages, you can go to the next page with Select, watch out that the B Button will go back to the Map Select!

I will actually try to explain to the best of my abilities, everything:

  • Page 1:
    • COMMAND: The amount of orders you can give to units in a single turn.
    • TURN: The amount of turns in a match.
    • 軍モード (Army Mode): The amount of army organizations that can be selected (explained later).
    • 勝利条件 (Victory Conditions): Switch conditions that defines a victory.
    • PLAYER: Defines up to 4 players if they’re either Human, Computer or None (NOT)
    • 生産モード (Production Mode): It seems to be related to unit production but I haven’t fully understood it I apologize…
  • Page 2:
    • ORGANIZATION: You can select army organizations here per player, I will explain what’s going on about it after this list.
    • CAPITAL: The starting military funds of each player can be defined here.
    • TEC: Unit Production Technology, it can be set between 1 to 20.
  • Page 3:
    • CAPTAIN MS: You can select a Mobile Suit captain… but I don’t understand how it works.
    • SOUND: You can select between Mono (モノラル) and Stereo (ステレオ) here. For some reason, Mono is the default.
    • 補給 (Supply): You can select between Manual (マニュアル) and Auto (オート)
    • BGM: You can select music for a specific player’s turn.
    • CONTROL: You can select a controller for a specific player’s turn.

Press START once you’re done, to start playing.

Now, a word about the Organizations: Army mode in the base game can be either 6 or 12, here’s what can be selected per player:

  • Army Mode 6:
  • Army Mode 12:

When you have the extra content enabled, Army Mode will change to either 7 or 13, here’s the flags available in that case:

  • Army Mode 7:
  • Army Mode 13:

This flag is the new military organization available.

Hopefully this will clear up a lot of things, I also tried to look up differences between the retail Memory Pack release and the Satellaview download release, but I couldn’t find anything really different.

Now here’s the redump from techknight that you can use:

This dump is no different from all of the others except the date.

The sound of novelty and horse racing

Here’s a brand new Satellaview Memory Pack dump from Andrew Henderson, with some interesting content, to say the least.

This Memory Pack contains 4 files, filled with brand new undumped content, and everything works.

The first file is オキラクコウザ (お気楽講座), which is actually a first: This is the first dump of a playable Sound Novel Tsukūru DLC!
This is dated June 30th, 1996, and with a bit of a playthrough, this is a very silly one, and it’s fairly hard to find actual information about this.
It starts with a lot of instructions, and a choice between the main story, a minigame and to exit. I did not understand much, unfortunately.

To play it, load the Memory Pack with Sound Novel Tsukuru, select the first option, then the last option, then it should be after the two first samples from the base game.

The second and third file are KANADERU SCORE, which are Ongaku Tsukuru music data. The thing to understand about these files is that they’re basically SRAM backups, not very different in functionality than using ASCII’s Super Turbo File. Loading one of these would replace the SRAM entirely.
What is very interesting however, I believe these are actual downloadable content of some sort because these are some of the actual non converted music used in Ryōma de Yuku!

Normally, you use the convert feature of Ongaku Tsukuru to make a new file compatible with RPG Tsukuru 2 and Sound Novel Tsukuru, but you cannot actually convert back to an editable format, so this is either the Memory Pack of someone who actually made the music, or this was made available via broadcasts.

The fourth file is サテスポＤＸ５号 (Satesupo DX Vol.5), which is a magazine pretty much all about horse racing! You may remember that we have dumped some of these in the past, which also prompted the findings of new Satellaview music (which were in the BS-X ROM the whole time), there’s really not much to say as we don’t really read japanese properly, but we still think these magazines should be preserved too.

The overdump data after those is from a RPG Maker Super Dante title, it cannot be differenciated from any of the Super Dante games like Jewel of Live or Cock-A-Doodle-Doo, there’s nothing to recover.

Here’s the file with the full Memory Pack dump. Again, thanks Andrew Henderson for the dump!
