Re: Emulator is inexplicably slow!

And yes, the Express shit is next to worthless for creating anything non-trivial. If you are a student at most colleges, you can get a Dreamspark account and download the full version of various Visual Studios for free... as well as full versions of Windows Server 2003 (and all sorts of other cool ...

Re: Rom experiment with Zelda SNES to NES

The Rockman-style face overlay looks like the best compromise between appearance and sprite efficiency. A single face-tile shouldn't cause too many problems with other sprites on the same scanline.

Re: Strange color at Goomba in Super Mario Bros.

An unchanging color carrier phase from one line to the next results in some colored vertical lines looking wider than others. When a colored object moves horizontally, it's really ugly. This is because the edge falls on different parts of the color carrier wave, and thus affect width differently ba...

Re: Strange color at Goomba in Super Mario Bros.

I have here a 1980s Zenith green and black monitor designed for computer use, made long after color CRTs emerged, and it certainly does not filter out the NTSC color burst. Here is a picture of it running from a Model 1 japanese Mega Drive. The color burst shows itself in the form of vertical lines,...

Re: Strange color at Goomba in Super Mario Bros.

NTSC is only marginally backwards compatible anyway... nasty dot hatch patterns appear on old monochrome sets.

Re: Visual 2C02

This sure looks very interesting, but how am I supposed to use this ? @mikejomffit : The NES PPU does not have RGB output, and it was never meant to have any. The output signal is composite by the very nature of how the NES palette works, and it can't be otherwise. I understand this. However, the R...

Re: Visual 2C02

With the RP2C02 fairly disassembled at this point, would reproductions, featuring RGB output (with the changes one would expect) be feasible?

Re: Dead NES?

I've found the new connectors to be shitty brand new. Soaking them in isopropyl alcohol, then repeatedly sliding them onto and off of edge connectors made them work much more reliably afterwards.

Re: MMC3/Sunsoft-5B reproduction circuit boards. INL-ROM

I thought driving it directly with M2 would pitch it an octave up from M2/2, not the other way around.

Re: PPU Reset & Timings

I'm not keen enough on the electrical-engineering type knowledge on it, but I can tell you that the skewed-line effect on a CRT TV is affected by the contrast between the vertical line and the surrounding data around it, and is a product of the CRT TV's physical method of shooting the beam at the ph...

Re: How to make a famicom cartridge rom dump device?

I thought TapeDump requires you to have knowledge of which mapper the game uses. Don't many multigames use obscure, custom, or most importantly undocumented mappers, rendering the technique less than reliable?

Anyone want these weird Famicom-Nes pad things?

My roommate got two Hori FC NES pads in Japan. They are styled like Famicom controllers but are made to plug into an A/V Famicom or an NES. If anyone wants to buy one of them, $40 paypalled each will get you. This is just here for a picture reference, but it's the same one: http://www.ebay.com/itm/F...
