Chaos89P here, with -- oh crap, wrong forum.
Right, I have here Super Mario Doomsday, a SMB3 ROM hack. It's currently under stasis as I have no ideas for level design at the moment. This hack is meant to be done with as little ASM manipulation as possible. Yeah, as it currently stands, it is little more than a texture hack, and I don't want that. I also have a couple of videos related to this hack. I apologize for the inconsistency with the volume. Zip file for the demo is here. Please read the Readme first. ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Thanks for posting this up. Ill add this to my list of all the hacks im currently trying out. Thanks for coming in here and sharing this.
EDIT** Im getting a few glitches with sprites glitching up on levels. Is this something you already knew about>? Im using nestopia if it helps. |

Yup, and it was intentional in one of the levels. See, world 4 is called Error Isle, and that is a tendency, while I oughta remove that cloud in the castle. ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Hey. Since you helped me find a bug I wanted to repay your kindness with two fixes that I made in my SMB3. Here they are. 6502 may not be easy, if you need me to explain this to you in hex, let me know and I'll be glad to!

I haven't gotten that far in ASM programming yet. I'm still on the basics: LD* and ST*, basically. Thanks to infidelity, I have been thinking of adding a simplefied save function. However, I'm more concerned about level editing at the moment. I wonder where that wheel was gonna go. ____________________ Sorry for the stupidity.

Posted by Chaobomr If you want to learn the 6502 processor, use this as a reference: http://www.obelisk.demon.co.uk/6502/reference.html Also, might I recommend this as an explanation of what the mnemonics do? http://skilldrick.github.io/easy6502/ That guide by skilldrick is what I used when I was now learning NES ASM. It is very useful for beginners. Also, I sent you a PM.

New question: Where do these instructions go? I'm used to having line numbers (C++ and C#). ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Posted by Chaobomr Could you please clarify? By instructions do you mean the mnemonics/opcodes? Also, I personally use Notepad++ to do ASM coding and then assemble with ASM6 in all my hacks. (Except for Game Boy ones like Pokemon, in which case I use RGBDS.) ____________________ At the end, when the day is over, the only one left to face is yourself.

Just... where in the ASM do these mnemonics go? I'd like to be able to just quickly locat and insert these opcodes into the ASM, and I don't know where in the code to look. ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Posted by Chaobomr Mnemonics are like... LDA STA etc. The opcodes are those three-letter mnemonics in hex. Like... $A9 would be to LDA #$__. So right there, we'd be loading an immediate value. You can also have stuff like LDA $00, which is zero page and the opcode would be $A5. If you got Southbird's SMB3 disassembly (try googling), then go to the "bin" folder, then go to the prgs and basically find what you need to and go from there. The ones above are from prg003 prg010 and prg014. Control+F helps you find stuff fast in Notepad++. Be sure to minus $FF for every extra byte that you add. In SMB3, each bank is $3FFF bytes (4000) and cannot exceed that. You can also do bankswitching. (LDA immediate and a JMP.) EDIT: For example, say you want to fix the bubble code REALLY fast. Find it in the prg I marked, add the ADC #$03. ADC is add with carry. It is immediate so it adds 2 extra bytes. Find the $FF at the end of the prg file and minus 2 from them. When you're ready to assemble, go to the "bin" folder and double-click on the make.bat. Then, compare the changes to an unedited smb3 prg1 ROM and rip the changes within the bank in a hex editor. That's what I did with my SMB3 Extended when I fixed glitches and added the beta ghost house. Easy. ____________________ At the end, when the day is over, the only one left to face is yourself.

Alright, I have Southbird (had it for a while, actually) and the ASM can be easily loaded into Microsoft Visual Studio. How do I delete an $FF out of the code? I apologize in advance if this seems like a stupid question. ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Posted by Chaobomr Oh sorry. For this the assembler takes care of that. You don't need to manually take out the $FFs. I got it mixed up with my SMB1 disassembly where you actually do. Just makes the changes, save and make.bat it like I said and you'll be fine. Visual Studio? I use Notepad++ because the lines are numbered so when there is an error assembling I can trace the line in question and fix it. I don't do any other programming besides 6502 and Z80 ASM so I didn't know Visual could do the same thing. Cool. Here is the code for the box-in, too: ____________________ At the end, when the day is over, the only one left to face is yourself. Have you been true to yourself and made the most of your day? |

The box-in's missing. I like using various programming languages. It started with TI-BASIC and it just mushroomed from there. ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Posted by Chaobomr Can you please be more specific when you say "the box-in's missing"? EDIT: Oh, I see what you mean. You're saying when you assembled that it is missing. Well of course it is missing. That box-in code that I did that I sent you was custom asm code that I restored from the Japanese version. If you want me to, I can include what to do in asm. Do you want it? EDIT2: Here. But it is LONG and tedious. EDIT3: The Level intro SFX is stored in prg028.asm. If you want the exact one, I can list it for you.

Do I put the code that's commented out at BoxOut_ByVStart? How do I include the sync information? Should I just disassemble your version of my demo just for comparison? ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Posted by Chaobomr I actually added it at the end of my assembly work. I lost my original files way back last August, in which I fixed bugs and added code for the unused ghost house. If you want, you can do a hex comparison against a clean copy of your hack to find differences in hex. Box-out effect was done in December. 4 months after I lost my original files. What I did was JMPs to the code at the end of bank $3F. I added the sound which took no additional space at all, merely changing existing data. The way I added it to your hack was a simple copy + paste from my SMB3 hack using a hex editor. Though, it basically does exactly the same thing of the code I listed above. If you can't find it, I'll just give you the answers in hex. Cool. ____________________ At the end, when the day is over, the only one left to face is yourself.

So, it looks like my hack - and several others - will be in stasis for a little while longer. About a week ago, my computer broke and I took it to a shop to get it fixed. Last update I received was that the replacement parts have been ordered, but that was also a week ago, so... I believe I had an idea or two in my head, but since I was unable to implement them (I haven't backed things up in a while), I feel like I may have lost the inspiration.
Will update as soon as I get another one. ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Posted by Chaobomr I hope your computer gets fixed, soon. I really enjoyed the demo of your hack. If you need any help at all, just let me know. ____________________ At the end, when the day is over, the only one left to face is yourself.
