Re: Living without a personal smartphone

You have to watch out for when science gets hijacked by politics or profit motives. You can tell when it happens because the study will either intentionally use data with confounding variables or intentionally avoid investigating the original question. (For example, Monsanto funded many studies tha...

Re: Can't get my old famicom work

We don't know what type of AC adapter your famiclone was designed to use, so we can't tell if that one would work. It could destroy your famiclone.

You need to open your famiclone and look inside. There's no other way to tell.

Those aren't really any more trustworthy than Wikipedia. Can you direct me to peer-reviewed studies instead?

I did not do a web search for them, but I keep coming across them because I study health a lot. Be careful. Search algorithms tend to promote material that makes people angry, and claims of intentionally hidden dangers will make people angry even if no credible research has been able to identify an...

Re: Demo Vision

I was thinking maybe i could try swapping these out ( all together or one at a time) and if the EUR one starts working... i know which one or which few i can reburn... Or if the NTSC one stops working. Swapping the ROMs (the smaller chips with stickers) between units should be a pretty reliable tes...

Re: Modern Mapper Replacement Chips?

*: Yes, some of the address lines are still multiplexed through the MCU; but they're not propagated in a way that would effect the timing; they change between bus operations (i.e. as a result of writing to a bank switching register), not during the operation. -- Hence the timing would not need to b...

Oh, weird. I see it too. For whatever reason, phpBB is adding some CSS to the icon, but only for that topic on those pages: <dt style="background-image: url(./images/icons/smile/redface.gif); background-repeat: no-repeat;" title="There are no new unread posts for this topic.">

Re: Square colon notation?

I can't find this word in any dictionary but words like "×-mas" and "×-tal" indicates that it's pronounced [kriss] which is close to the Swedish word for it (kryss) so I'm guessing it should be "cryss". In xmas it's an abbreviation of Christ (from Χριστός), and I suspe...

What are you clearing when reading from the status? The vblank bit is cleared by reading, but the sprite 0 hit bit is not cleared by reading.

Re: What is one thing about a retro console/computer's specifcations that you would change?

You can disable blink and enable high intensity background colors on EGA and VGA too, but the method is different from CGA. Since we're talking about things we'd change about retro computers, I'd say the IBM PC really could have used a functional vertical retrace interrupt. CGA doesn't have a vertic...

You can find the NES files inside holy-mapperel-bin-0.02.7z in the "assets" section of that page. The file names indicate the header contents.

The flash ROM uses bit 6 as a status indicator. When the ROM is busy programming or erasing, bit 6 will flip each time you read it.

You can read the SST39SF010A / SST39SF020A / SST39SF040 datasheet for more details.

Re: Simplest way to integrate an nsf to your game code.

Since "famitone2.s" is the CA65 version, you might instead want to build it as a separate object file and then link it with the rest of your code using LD65.
