I am currently working on a hack of SMB2 called Doki Doki panic 2. I am having some trouble with graphics, the sprites for the main characters in Doki Doki panic are too short. When I pick up a veggie from the ground it floats above their heads. If anybody knows how to lower the veggie please let me know it would be greatly appreciated. *Edit* Also I was wondering how I would hack it to where when the character is on their last hit point they don't shrink. Thanks

Posted by 32x1000 Well, what I would do is use FCEUX's PPU viewer to see the tile numbers for the characters. If it uses 4-6 tiles just look up the tile numbers with YY-CHR (a GFX editing tool) and make them bigger. Try that first as they probably don't use their full tile space. For the power-up, if you don't want them to shrink look up the LDA which contains their value using FCEUX'z Code/Data logger: http://www.fceux.com/web/help/fceux.html?CodeDataLogger.html Here are SMB2 helps: ROM Map: http://datacrystal.romhacking.net/wiki/Super_Mario_Bros._2:ROM_map RAM Map: http://datacrystal.romhacking.net/wiki/Super_Mario_Bros._2:RAM_map Tools: http://www.romhacking.net/utilities/181/ and http://www.romhacking.net/utilities/429/ ____________________ At the end, when the day is over, the only one left to face is yourself.

Posted by 32x1000 LDA is load accumulator with a value. Register A is responsible for handling logic and arithmetic in the 6502 processor. In this case, you will be searching for an immediate value. It is pretty clear that you don't know ASM, the programming genre of NES hacking. I suggest that you try to learn it, or this will be a tedious task. If you have questions about any of the mnemonics, PM me and I will be glad to explain them to you. Or, you can ask me here. I know it may seem hard, but try to understand this link. What you don't understand, ask. http://skilldrick.github.io/easy6502/ ____________________ At the end, when the day is over, the only one left to face is yourself.

Don't forget about STA, LDX, LDY, STX, & STY. LDX & Y do the same for X and Y registers while STA X and Y store the register's current value to the memory location of your choosing, within reason. Shanem forgot about this for more mnemonics. It's also in the post for Super Mario Doomsday, if this link doesn't work. ____________________ Sorry for the stupidity. That jerk will be dealt with in the most insane way possible. |

Posted by Chaobomr Thanks. The reason I didn't give him too much detail was that I was afraid I'd overwhelm him. Though, the reference sheet is good. Did you know about these? You can do transfers, but only through the accumulator. Like, say I wanted to store the value from X into Y, I cannot do TXY, I would need to do TXA then TAY. It sucks, though I never had an occurrence where I needed to do that. Thanks again for pointing those out, Chaobomr. ____________________ At the end, when the day is over, the only one left to face is yourself.
