Re: MMC5 and third pattern nametable

Assuming the nomenclature is the "A" set is associated with registers $5120-$5127 and "B" set with $5128-$512b, as it is the case in both Goroh's document and Dish's notes: If your PPU code follows the same cycle-by-cycle memory fetch pattern that the real chip does (which it loo...

Re: MMC5 and third pattern nametable

Post said that it synchronizes to the two NT reads at end of scanline, then counts down 256 dots or 128 total memory accesses. And why does it count 256 dots? AFAIK, the MMC5 can't count "dots", as those can't be seen directly on the PPU bus, but it can count memory accesses by watching /...

Re: SPC700 is similar to Paula ?

This guy is simply a stupid troll IMO . +1 I am unfamiliar with Paula, but it sounds like it has much less features than the SPC700 : Not a dedicated CPU for sound, no fine left and right volume control, no ADSR volume enveloppe, no noise mode, no pitch modulation, no echo buffer, and obviously no ...

Re: MMC5 and third pattern nametable

When using 8x16 sprites, the PPU ignores the sprite pattern table address I assume here its saying it ignores 2000.5 isn't it? No, it's refering to $2000.3 which selects the pattern table for sprites. This bit is ignored when $2000.5 is set (8x16 sprites) - this is always the case no matter the map...

Re: Public transit

When I want to go somewhere, if it is close then I would prefer to walk. [...] (But, it would be better to reduce the pollution of light, noise, chemicals, etc by cars and trucks and also bus. Therefore, I should prefer to walk; but, some people don't like to do walk.) I'd love to walk if the way l...

Using artificial intelligence to give clearer description of hardware on the Wiki

When working on a technical documentation such as the NESdev wiki, it's hard to keep the information consistant and easy to understand. Common pitfalls would be : Have the necessary information scattered on a page, or even worse on multiple page. Make assumptions that the reader knows something. Or ...

Re: More NSF Requests

I've noted that the NSF rips of Square no Tom Sawyer I have arround are somehow bad rips. The music seems to work at 1st glance, but in most songs the track are stuck on a repeat loop and don't play the entiere song. Sometimes the different channels aren't looping simultaneously. Is there a correct ...

Re: Public transit

Not in my city right now. The bus service here has 58 days of scheduled downtime per year: the 52 Sundays and six major holidays. Today is a Sunday. At least on those days when it is in operation, it still accepts cash. USA are well known for it's (compared to other 1st world countries) terrible qu...

Re: MMC5 and third pattern nametable

Don't worry it's fine to ask questions and having some trouble not getting it to work. First of all, there is something weird and unique about the MMC5 in that it monitors writes to $2000 in order to keep track of whether the PPU uses 8x8 or 8x16 sprites, and the bankswitching registers used to rend...

Re: DMCA Anti-Circumvention Laws and Video Game Dumping

Actually public and private things are and to some point always were intermixed. For example here in Switzerland you can have your account in a public bank, but the cart will still be handled by one of the major private companies you mentioned. Some communities have some form of public car rental se...

Re: Questions & Clarifications regarding APU Sweep

The Wikipedia page on barrel shifters is just that - it is a page about all barrel shifters, not the very specific one in the NES APU's sweep function. Obviously the sweep barrel shifter does a right shift and not a rotate - if it did a rotate the frequency would not sweep but instead quickly rotate...

Re: DMCA Anti-Circumvention Laws and Video Game Dumping

What I mean is the parking itself is a symptom of the car, a "nice to have" that has been morphed into a "need to have" by the forces of commerce and industry. The car is a product you purchase from a company benefitting from decades of social manipulation. It isn't a need, but ...

Re: Final Fight 3 (mapper 90), get rid of multiplier, issues

This means that this game used an ASIC multiplier just to do 2 constant by constant multiplications, which could have been done at compile time 2 multiplications by 10, which are very easily done in pure 6502 And that's all ? If I understood well this is just a Chinese bootleg, but still it sounds l...

Re: Help needed getting MMC5 PCM to work!

Okay!.. that explains everything. I had really thought that they had built some effective way of running the PCM. Honestly now I am wondering why they had went through the trouble of making the PCM but not implementing a FIFO to be used during scanline IRQs. It would've been an absolutely groundbre...
