Re: I finally got a way to fix the triangle channel bug in Ufouria!

I looked at the data for Ufouria and found a way to fix the triangle channel bug. I made an FCEUX cheat to fix this bug: 0087?00:17 I like Ufouria! Could you tell us more how you found the cheat? (Did you find out what address 0087 controls? Did you find any documentation about the Ufouria or Heber...

Re: Hori Game Repeater

1. Thanks for thinking about capturing some RAM contents. The only way of reading the memory content that comes to my mind is [...] Replace the SRAM with socket and make [something to plug into the socket...] Is it possible to connect the logic analyzer to the 8 data lines and the enable line of the...

Re: Hori Game Repeater

krzysiobal, thank you for providing your logic analyzer dump! I had fun looking at it. Here's my analysis: hori-game-repeater-example.zip Here are some things I noticed: In the recorder signal, the 3rd and 4th bytes of the 4-byte header appear to indicate the last address used in memory for the reco...

Re: Hori Game Repeater

I don't know Japanese, but I used Yandex Translate Image to OCR and Google Translate to do a translation of the side of the box with notes on it and sections 3 and 4 of the manual. I manually picked some characters from Windows Character Map to get some symbols and to correct a few of the OCR mistak...

Re: Sometimes can't access nesdev.com

It's explained more in depth in the linked thread, but RCWN completely subverts the browser's cache by re-requesting all content, on the off chance that re-receiving it from the server is faster than retrieving it from the cache. Nesdev is likely seeing this as a DOS attempt (multiple repeated requ...

Re: Question about Zelda 2 sprites

I tested the values by using the freeze function in Mesen's memory viewer to set the values I wanted, then I pressed the "frame advance" keyboard key 16 times to observe the effect. Glancing at the code, my initial guess is that the stuff that gets stored at $3D6+X is used as a sub-pixel counter. If...

Re: Question about Zelda 2 sprites

the speed is only a 4 bit value stored in the high nybble of $70-$75. The value is not signed I would describe the value as being an 8-bit signed value, but it represents the speed in sixteenths of a pixel per frame, that is: hex 10: right one pixel per frame. hex 01: right one pixel every 16 frame...

Re: Would it be possible to mod a NES to have that "Allow more than 8 sprites per scanline" feature from emulators?

What games use that? I’m kinda curious to see how it looks. Nesdev Wiki Sprite overflow games - Use of excess sprites for masking effects Can you make another LUA (for Mesen) specifically for detecting masking effects? [...] To give an idea on how to code this script, looking into the Mesen code be...

I investigated Mario Paint's tempo and found out the following: address: $7E0C28 length: 2 bytes type: unsigned 2-byte little endian integer description: position of the tempo slider in quarter pixels, valid values are 0 to 159. The 0 position is when you drag the slider all the way to the left. Eac...

Re: Anti-spam proposal

What I can do is start gradually deleting pre-2020 users with no posts Even if a user doesn't post anything, one useful feature of having an account is that the site remembers which posts you have read. On some forums, I would set up an account just for the purpose of having the site remember the p...

Re: Late 1980s / Early 1990s Memphis Style in NES Games

Parts of M.C. Kids might sort of qualify. The early levels feature bright colors and repeating shapes in the grass and columns: Map of the first level (from The Cutting Room Floor M.C.

Re: Why preserve video games?

One argument I can think of is it's hard to predict what future historians will want to investigate. If digital preservation takes up little physical resources, why not preserve as much as possible for future researchers to study? I'm not sure how strong that argument is. I'm having a hard time comi...

Re: Does RF Famicom work with "cable-ready" US TVs?

I just wanted to point out the term "cable ready" and tepples's advice to look for a switch for AIR, STD, HRC, or IRC dates back to analog-only TVs. Modern TVs with digital tuners will typically just offer a menu item to choose between a cable signal or an over the air antenna signal. On some TVs yo...
