Can someone explain these parts a bit? The wiki page of VRC6 is somewhat hard to understand. What I've understood, there are some modes that are not useful or very practical. I don't need to know details of these modes, but would like to know which ones are the useless ones and in which situations a...

A very common way is to have a table of numbers from 0 to 15, or however many banks you have, and do an indexed store on top of that table so the 2 numbers match (eliminating the conflict issue). LDA #bank TAX STA table, X table: .byte 0,1,2,3,4,5,6,7... It's effectively instant. The bank will be r...

The wiki article on this particular mapper states "The original UxROM boards used by Nintendo were subject to bus conflicts, and the relevant games all work around this in software.", so I was curious about how is this usually done and what would be a good and reliable way to implement it?...

Another way to do it is keep track of the internal register writes with a Lua script, and have the Lua script call debugger.hitbreakpoint() when it sees the write you want. This might be the best option. For now I only want to know when the game swaps PRG banks if at all. CHR bank swaps are usually...

Is there a way to make breakpoint in FCEUX that gets triggered when the game swaps PRG banks? If it is any of help, I believe the game in question uses MMC3 (iNES 004 iirc).

You want to play the European release of Mega Man 1 on an NTSC NES anyway. Both the game and the music runs at the same speed as the original NTSC version, so if you play it on an PAL console, everything will run too slow. I actually tested this on emulator by shooting a single shot right after spa...

I don't think it was mentioned here yet, but one use for removing region lock on PAL NES is the ability to play both PAL-A and PAL-B games. I wasn't even aware of that there are "sub-regions" in the PAL region code until now. I received my Mega Man cart today and when it was constantly res...

I just imported an AV Famicom myself, instead of trying to mod anything. They weren't particularly expensive a few years back (I was only screwed by the import taxes imposed by my country). This option could be better since most games were released in Japan anyway. Lastly, I'm assuming flash carts ...

-Do famicom games run correctly on PAL NES? Sometimes. Really depends. The speed they run at is what I'm mostly concerned of. If they run at incorrect speed it might be better to just get NTSC NES and mod it instead. I'm assuming the PAL NES power supply works for NTSC NES as well. I doubt they hav...

I was thinking of modding my NES to be able to play Famicom games on it and enjoy the expansion audio as well. I need to ask a few questions related to them to know if it is even worth it on PAL NES. -Do famicom games run correctly on PAL NES? -Is expansion audio present and processed on NES carts e...

btw is there really motion blur? that's not something i've noticed. Not necessarily blur. I just didn't have a better name for it and that's what is looks at first. Some things that change every other frame such as bomb explosion in RECCA and air ship disappearing (at the very end) in SMB3 look lik...

Everyone who has played on both emulator and on real NES probably has noticed how different they look visually. NES has some blurry edges, slightly inconsistent color (some colors changing slightly), contrast issues (might be the TV as well, but not sure), a bit of motion blur, scanlines not perfect...

Now that I tested the controllers again they seemed to work correctly again. What I did yesterday was that I opened the controllers and washed the buttons and the rubber pads. This also seemed to fix issues in the controllers where you had to push the button harder than normal to get the correct inp...

An important detail I forgot to add is that the false input on start doesn't happen immediately after A or B is pressed. It usually has a delay up to few seconds. Usually it is around half a second. Not sure if this changes the suspicion on what could be broken though.

I would have guessed the same thing if this happened on all of my controllers. The 4th controller is fine and doesn't cause any issues. All the other controllers did this in games that don't even use DMC.

EDIT: Didn't the wiki page say that this is fixed on the PAL NES?
