still looking for someone to do this.

maybe we just dont have the right ROM, and this being a beta rom or something. i dont know. I looked on youtube and there's videos by "keith good" showing all the dungeons, final boss fight and ending. https://www.youtube.com/results?search_query=feng+yin+dao+%28nj072%29+%28ch%29+keith+go...

okay got your savestate and saw the wrong teleport to other place then. Yea. unless the game actually crashes with that, then there's no way im ever going to be able to figure that out, cause i know absolutely nothing about this game, never heard of it before you started your thread the other day. ...

Oops, i missed 1 of the music engine JSR's. (delete my custom JSR cause it was "during" NMI) Sorry about that. May still be more spots. It's impossible to know truly 100% for sure cause we dont have source code of this game. So i can only do these edits in the hex editor. https://www.medi...

Well i tried something before i saw your reply pwnskar. I open the "find search" window on fceux hex editor. search for all existing "8D 00 80" ..and change them to a JSR to 1 spot at the end (JSR $FFD0) - 7FFE0 hex -- there was like 50 of these literally. and then i put STA $7F...

Yea sure. Okay first, i downloaded the rom from this website. Just picked the 1st result on google search *mod note if this aint allowed, then i'll remove this link* http://nesninja.com/game/nes/feng-yin-dao-nj072 Strange thing. This ROM says it's 110 kb, but after you save in the hex editor, it ch...

yea it's totally random when it happens. This is almost 99% certainly when the game does what i described earlier. While's "halfway" in the middle of a bankswap routine at the end of a frame (scanline 240) ..it gets corrupted. And i noticed, hmm, it restores the 8000-9FFF memory, but it d...

good news everyone. I found the problem for this game. First, i dont know if it'll magically affect any other places that crash, cause im not going to play through the entire game trying to hunt down problems that can be anywhere. It took me like over an hour to figure out where the 1st dungeon is....

that's a good sign. shows that anything like a branch, or a jump is wrong (still doubt it) Or more complex and possibly more liekly, a JSR/RTS combo screwed up the Stack returning to the wrong address. That's only just step 1. When i have problems on my game, Megaman Odyssey, i use that "break...

Here is some information I took from the game i hope it of some help if anyone wants to consider this.

In my opinion, a talented nes rom hacker with asm hacking experience could take care of this. But you're still in the same boat with them; rom hacking is tedious and painful. They do it because they have the primal motivation to do it; if this game inspired that motivation, it would have already be...

I'm personally not interested in this at all but... here's something the original poster can do that could be very helpful to someone that's interested. Go to where the game supposedly crashes at... or just right before where-ever it is. Make sure your using the FCEUX emulator. Click Debug ---> Deb...

How expensive and time consuming could it be to mostly fix a game that is around 1 hours in length plus the core of the game already there and you do not even need to try hard to find the glitches You're looking at this as if games were like Word documents, where you can quickly find typos, erase t...

i can not imagine And that's the problem. You know, I admire rom hackers because they put in a tremendous amount of work. It takes them years to hone that skill too. If you were to put a price tag on the work some of the hackers do, you'd be shocked! And they do it for free. If profit is not a moti...

i can not imagine a game that is ruffly around about an hours in length be that hard or take that long to fix. Most of the glitches happen on the over world map anyway mostly random teleporting you to your last check point or right outside a dungeon which the game constantly is braking non stop. You...
