| If only it was possible to make RAM dumps with the current 3DS homebrew, we'd be able to check out how those SEGA 3D ROMs really work, and ideally get some dumps with certain extra features enabled... |

| Doing some RAM dumping and it seems as though GB/C games get patched with invalid opcodes (replacing bytes with FC). Dunno why they do this, probably part of what the patch does.
I'll try and get other RAM dumps too. ____________________ Sometimes I English very well but sometimes no. |

If I had to guess, it's possible the emulator handles FC opcodes in an abnormal / nonstandard way. ____________________ |

| I've been working on finding differences independently, though I used a different method from the method used in the first post. Basically, I've used the method described here to dump the 3DS's RAM while I had a Virtual Console game running, then I was able to find the ROM within the dumped RAM. All GB/GBC ROMs (and possibly other systems, I haven't looked at any others yet) start at 0x28002C4 in a RAM dump. (Note that my 3DS is on 9.5.0-22; this method is not possible in later firmware versions.)
I've made some notes here, which are currently disorganized at the moment, but at least you can see internal changes for the games that I looked at. I've looked at the following games: Donkey Kong Land This is completely identical to the original English version. Donkey Kong Land 2 The flashing that occurs in Lava Lagoon, Glimmer's Galleon, and Clapper's Cavern was toned down (reduced to half of its original blinking rate). Donkey Kong Land III This is completely identical to English version 1.1. Super Mario Land 2 On the screen where Mario is standing in front of Wario's castle, the flashes from the lightning strikes have been toned town (the 3DS version has fewer flashes whenever there is a lightning strike). Metroid II The title screen had a subtle change. Every 1,024 frames, the screen flashes 3 times on the 3DS, and 4 times on the Game Boy. Strangely, the blinking rate was not slowed down at all. Wario Land 3 I haven't finished looking at this game yet, but I do know that some cutscenes have altered color palettes. The most notable one (that I've found so far) is that when The Steep Canyon becomes accessible, there are dark gray colors in the 3DS version whenever there is a lightning strike (the Game Boy version uses white colors). (This is easier to understand if you view this animated GIF.) Some cutscenes share color palettes, so this change also affects other cutscenes as well. Super Mario Bros. Deluxe
OK, I haven't really looked at this one yet, though I did notice some FC opcodes. I did notice that people already found some changes in the 3DS version, so this is a low priority for me. Other I also have a few NES/FDS games on the 3DS, namely Super Mario Bros. 2 (Japanese), The Legend of Zelda, and Zelda II, but I haven't looked at these yet (short of dumping RAM when running these games). I'll get to these after I get to all the Game Boy (Color) games. Because the 3DS needs to be updated to the latest firmware in order to access the eShop, I will never be able to look at any other game unless a future exploit is discovered. (And I will need to update my 3DS at some point anyway, because I have plans to use the eShop in the future.) But hopefully, other people will be able to find Virtual Console changes. By the way... should the Bob template on TCRF have a parameter for Virtual Console changes? Considering there are quite a few games that have VC changes, I think it would be helpful (especially having a category for them). |

Are you managing to dump the patch files from them too, or just the ROMs? Because the patches are pretty important, too.
(I think what we're getting from you is the patched-ROM, and the other person gives the clean ROM + text patch, so having the full picture is good) ____________________ |

| I have only the pre-patched ROMs. I am not sure whether it is possible to obtain patch files with the method that I use, nor am I sure if it is possible on the firmware of my 3DS (9.5.0-22). I'm not familiar with the method that einstein95 uses, nor do I know the firmware of his 3DS. I'll try to find a way to get patch files at some point, though... but for now, I run a binary comparison between the pre-patched ROMs and clean ones, and then I use BGB's debugger with read/execute breakpoints to find any differences. While I understand why the patch files are helpful, my method is at least better than nothing at all. |

| Thought this was the most relevant topic:
* Paper.Mario.VC.PAL.PROPER.Multi4.Wii-PiKMiN (extracted .romc file decompressed with romc * Super.Mario.64.PAL.PROPER.REPACK.WiiWare.Wii-OneUp (.rom file and .t64 patch files) EDIT: Old things by Xkeeper: http://xkeeper.net/private/vcproject.html ____________________ New Super Mario Bros Beta Replica |

Maybe this topic you've linked to could be moved to this board, and be merged with this one for a general all-VC topic?Originally posted by Hiccup |

Originally posted by Hiccup I was actually not opposed to the idea of merging the threads, thank you very much. Never did I say anything to the contrary. So much for your "obvious fact". ____________________ Sometimes I English very well but sometimes no. |
