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...

Re: Mario Paint (Music Maker) REing

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. Kids Prototype - Level Changes ) The text screens (used for the game over message, the bonus game title card, and t...

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...

Re: Hyperkin SNES Mouse cannot software-cycle sensitivity

Rainwarrior, thank you for measuring the ball, roller, and counting the holes on the wheel. I was thinking about it often at work today. You already came up with similar results as below (the measurements suggest about 50 counts per inch), but I wanted to chime in with a different way of explaining ...

Re: Hyperkin SNES Mouse cannot software-cycle sensitivity

Wouldn't inches per second values be related to how often you read the mouse?: If you are reading the mouse once per frame and a value of 3 appears to be 3 inches per second, then if you change to reading the mouse every other frame, a value of 3 would now represent 1.5 inches per second. If you are...
