Re: Has anyone tried to obtain an "Official Seal" from Nintendo for their game?

Nintendo had an even tighter grasp on the supply chain in Japan during the NES and SNES eras. Nintendo franchised game stores received at least 10 times as much stock as independent stores in exchange for letting Nintendo dictate pricing, game placement, signage, etc. Yup. Independent shops signing...

Re: Sharp Famicom Titler

I wonder how the Graffiti-like interface works? Nothing else looked too unusual. There are two ways to "free-form" draw on the Titler. The first is when you are using Famicom games, the stylus pad and the buttons on the side are the only ways to "interact" (if you can call it that) with the Famicom...

Re: 6502: Index to bit index

Thanks you all for the replies. A table it is. BTW, why does wla give an error for this: table: .db 00 lda table,x I'm used to using the y reg when reading from tables. Perhaps code cannot be in the 1st column of text (reserved for labels and assembler directives) and thus needs spaces or a tab bef...

Re: How to disable copy protection on Twin Famicom

The power board perhaps also needs a quick fix. Shown here: http://forums.nesdev.com/viewtopic.php? ... 98#p129898

But yeah, if a disk doesn't LOAD, then it's most likely losing its data.

Re: FAMICOM CONTROLLER IN TWIN FAMICOM

Try turning off all savestate / Up+Select to reset, etc. functionality that the Everdrive provides. Perhaps its ingame controller reading is interfering with or blanking out the expansion controller's data going to the game.

Re: VRC5

(the core meaning of 太 is something like "greatest", "grand", "very", "thick" or "fat") where 太 is read as "ta" ("tai" is also possible, but it looks like there are furigana above it which explains the reading). No, it's more like sound association with the words "compuTER" and "kid" or "boy". Thin...

Re: Fake John Wick nes game on real nes

You can use the straight horizontal line of the barrier right below the buildings as an entire scanline for palette updates. Turn on the greyscale bit and all colour emphasis bits, and do the remainder of your palette updates. This at least masks the palette colours a little bit as they streak acros...

Re: PPU BG rendering one dot early

I don't really know about all Famiclones, but I noticed a bug like this in my old DrPCJr clone console. Here's what I wrote about it back then: "The Doctor PC Jr's PPU emulation is not completely accurate and is a little quirky. The BG is offset by one horizontal pixel to the left. So, sprites and t...
