Re: simple dev cart for Famicom?

The mod is for the FDS disk drive (to make it possible to write the whole disk). If you're using the FDSStick as a replacement for the drive (i.e. just FDSStick + Ram Adapter), you don't need to mod your drive. If you want to use it to make copies of disks (FDSStick + disk drive), you might need the...

Re: Nes emulator for playdate?

I'm not too familiar with this system but judging by the specs it should be possible at full speed. Is it an open platform or do you have to use the SDK provided by the manufacturer? It's a closed platform. The SDK is freely provided, but explicitly proprietary . I believe there's some signing/encr...

Re: snes assembly - beginnings, a few questions (wla-65816)

For 65816 I personally prefer ca65 for a bunch of reasons but wla-dx is pretty capable.

I'd suggest using whichever feels more comfortable for now. When you already know your way around one, learning and switching to another one isn't so bad.

Re: snes assembly - beginnings, a few questions (wla-65816)

The set of operations which work on 3-byte (long/far) addresses is more limited than the 2-byte (absolute) ones. All of the read-modify-write instructions like INC/ASL/ROR/etc. are missing, along with some others, though you can use long addresses with stuff like ADC or CMP. There are a few options ...

Re: snes assembly - beginnings, a few questions (wla-65816)

I thought the wram banks are as follows: $ 000000-001FFF $ 010000-011FFF $ 020000-021FFF ... $ 3F0000-3F1FFF. No, those are all mirrors of the same block of RAM. That first 8kb of RAM ("Low RAM") is available in half of all banks. This means it can conveniently be accessed without having ...

Re: PowerPak MMC3 jitter fix for loopy's mapper

I did spend a little time looking into that but saw no reason why the various bits of the counter should behave differently from each other, so it's got to be analog mess. Thanks. I was curious why it didn't seem to be a feature of Trirosmos' proposed verilog in any obvious way. It could probably b...

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

1. What's the assertion on line 4376 of famistudio_ca65.s?

2. The missing memory assignment might be an issue with your CFG file. What does that look like?

Re: PowerPak MMC3 jitter fix for loopy's mapper

jittery pattern: seems to not get the extra clock once every 12-14 frames? After thinking about it, I would bet this does not happen on the real thing. (Am currently acquiring a Wario No Mori cart to check.) I believe this sporadic (but almost regular) flicker is due to having to replicate the anal...

Re: Extra notification e-mails

I think I've been getting delayed e-mails (where I had already read the thread hours before) for a few weeks, but before that it was basically instantaneous. The sudden delivery of 11 e-mails in one night had never happened before, it was always just one at a time until that point. I wouldn't actual...

Re: Extra notification e-mails

Well I got a notification e-mail for brizzo's reply to this thread several hours after I read it.

The system is clearly keeping track of what I've read, it gives me the red badge in the top right when I haven't read a reply yet... it just seems that the e-mails are getting to me with a lot of delay?

Extra notification e-mails

I've been seeing the occasional e-mail notification for subscribed threads I'd already seen. Today I got like 10 e-mails at once of this nature.

I'm guessing the e-mail notifications have been a bit delayed and/or getting piled up in a backlog?

Re: is mario paint possible on NES?

Mario Paint has 16 colour graphics. NES could do something similar with 4 colour graphics. The main problem is that normally CHR-RAM is only 8kb, which is enough to cover only half the screen, and after the first 4k you have to do timed splits to switch to a new CHR-RAM page. For example, with MMC3 ...
