| I usually shy away from NES hacking, but today I spent many hours playing with FCEUXD and I'm glad I did. Even *I* can make Mario change into Hammer Mario when getting hurt or something...heh.... or Mario 2, have Mario pull up a flying carpet out of the ground instead of a radish. Heh... Great job on this project all involved, I can't wait to see what people can do with this thing. Even strange little things (like pulling up flying carpets for example...heh...laughed for about an hour tossing carpets around..heh heh).  |

| Hi there. This is probably a real newbie post but please stick with me! I'm just getting used to FCEUXD, and am using it to do some text and title graphic editing on Metroid. I've read through the faq and related posts but couldn't find the answers. Basically- using the hex editor, I can save text string changes under View- Rom File. The changes I make don't seem to appear 'on-the-fly' unless i make those changes in the 'PPU memory view'. Unfortunately, whenever I save changes made in PPU, they don't appear the next time I load the rom. Is this supposed to happen? Also- I shifted a few title tiles around to create my own graphic, but when I save these alterations in either Rom File or PPU, they don't appear to save and next time I load the rom the tiles revert to their original positions. Could this have something to do with not using a stripped rom? I tried to strip the header with Ucon64 but it corrupted the file, and I'm not using the logging facilities or anything. I fear the problem is simply that the changes I make aren't saving for some reason, though I can't explain the string changes saving ok. Strange to me.. Thanks very much for any help, Regards. |

Originally posted by midget35(wow, what a bump) Regardless, to have the ROM changes show up, you'll need to likely reload the room (go out/back in) or restart the ROM. The PPU, as far as I know, just shows the current one and is erased after it's overwritten by something else |

| Ah, no wonder FCEUXD was so highly reccomended. This is like its birthplace. It's great. I wish it had a turbo option but I guess it isn't really neccesory. | |||

| Had my hopes up for a second that more features were implimented and was going to be distributed in the next few months. Heh, one feature I'd like in the next build is definitely a debugger that snaps when certains values are run through the break point set. ... seems like that's being worked on last I checked, I just don't have an idea of when/if it's going to be released since the project went open source. Might want to sticky this, make easy access for newbies to know about/get FCEUXD. |

| And in the next build they need to include the keyboard shortcuts in the read me document.. I had to press random buttons till I found the Pause key. Not criticizing. I'm just not sure if it's been brought up before. | |||

Next time, instead of bumping such an old topic, just start a new one. Falsely getting people's hopes up is bad bad bad.  |

| Sorry about bringing this thread up. Thought I might have been asked to repost here anyway if I'd started anew. So my understanding is that any changes I make in the PPU show up temporarily. Fine, but if I copy that information to the rom viewer at the same address and save it, shouldn't it be permanent and present next time I load the rom? Because at the mo only text changes are saved. |

Yep, that's exactly what I've been looking forward to being released. Indeed, the people shall rejoice upon the new release of FCEUXD with this added feature. |

| Is there a way to save aesthetic graphic changes made in the PPU, so that they are a permenant feature of the rom? | |||

| You are actually editing the PPU in the hex editor? I don't think it's possible to save the changes made there. Nor will it ever be possible. | |||

| Yeah, I need to read up more because I'm starting to confuse myself now. I just can't see how the graphics are ordered per-room in the rom view. There seems to be no consistency, which is of course not true. the title graphics layout is the same in the PPU and rom, albeit they start at different addresses. Yet this does not seem to apply for ingame screens. I'm really thrown out by it all. |

| The hex editor cannot save changes to RAM or PPU memory, because this data is all generated by the game at run-time. The ROM is what you can change and save. And in fact, you can change the title screen in the very first ROM bank (in Metroid). The data is sort of "compressed" though. It's a very simple format, really. You just need to understand the PPU to edit it by hand. The title screen begins at ROM address $000304 The format is pretty simple: First two bytes are the PPU address (desination). Third byte is the length of the data to write. Then that number of following bytes is the data to copy. So let's take a look at the first PPU command used to build the title screen: 23,C0 - PPU address (destination) $23C0 20 - Data length, $20 bytes 00,00,00,00,00,00,00,00,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF,FF - The actual data The data following will be another PPU command, with the same exact format. The game continues to read more and more commands until a PPU address of 00 is read (upper byte, meaning if the first byte of the command is $00, the game stops drawing the title screen). Get Yoshi's NES docs, if you don't understand what the PPU addresses are for. The name tables and attribute tables are what's important to you in this situation. Now that the Metroid-specific stuff is out of the way, this can go back to being about FCEUXD. (Meaning, please continue this conversation in a new thread.) |

| My emulator thread got derailed like this too. Instead of getting suggestions on emulators to add to the list it became a slander nesticle and it's users thread. | |||

Originally posted by iamhiro1112 actually he's asking rather pertinent information about the functionality of an emulator. i guess what i'm really getting at is: what purpose did your post server other than to bitch about how you were pointed out as not knowing what you're talking about? it's not slander about nesticle, just fact. an NES emulator is a piece of software that attempts to replicate the NES hardware, on that basis, as a matter of fact and not opinion, NESticle sucks because it replicates the NES very poorly |
