Re: HLE DSP timing

Determining execution time of the DSP program is similar to the classic computer science Halting Problem. Not saying it can't be approximated, but by the time you take into account all the values of all the possible matrices and function input values, you're better off just executing the code direct...

Re: Wondering: how does the NES handle logic in a single fra

Project Mercury is the Game Gear.
And the Nomad (portable Genesis) is Venus.

Neither of these went by Mark VI or VII. The Mark naming stopped at V.

Re: Historical SPC700 development and Nintendo policy

It's probably worth asking The Fat Man (George Sanger) how the sound samples were baked or converted. Might mention it in his book, although I've only paged thru it: Sanger, George. The Fat Man on Game Audio: Tasty Morsels of Sonic Goodness (Paperback). New Riders Games. ISBN 1-59273-009-4. Probably...

Re: "return flase" causes PHP website to be hacked

I dunno. With the typical 32 GB of DRAM in PC's these days, there's probably a "mistake" (bit-flip) happening in a computer as often as once a week. Does it usually matter? No. But I'm just wondering when's the time for everyone to start using ECC across the board. My work laptop has already bluescr...

Re: 65816 C compilers

The Parallax Propeller 2 is due out this year, for real and not a lie. I have an engineering sample sitting next to me. It's 8 cores, 32-bit wide instructions, 200+ MHz clock speed. Two clocks per instruction when executing from the 512 long local core memory or when its streamer cache is full execu...

Re: Another strange piece of Mario trivia

I think you're taking it too literally. I can remember a flippant comment in Nintendo Power about creating a game that would require you to rotate your TV 90 degrees. Practicality then of course rears its ugly head. Miyamoto is a dreamer. And even that comment wasn't intended to be taken literally. ...

Re: NOTICE: All our homebrews are not ~real~ games

Looks like whoever's marketing strategy worked.
Would not have heard about this game if not for the "edginess", pardon the 90's term.

Good discussion tho.

Re: Finding shared code in NES games

This whole conversation makes me sick to the stomach. What positive unearthing can be produced by this endeavor? Giving some old bag of bones copyright holder the idea and probable cause to sue 20-30 years after the fact? Giving some up and coming coders a irreparable bad name because of alleged cod...

Re: What do schools have against teaching C?

My experience with a C programming class at college was that in the end we'd spent about 80% of the time dealing with all the intricacies of printf format strings. And yes under a microscope printf does some bizarre and tricky things that'll get points marked off. Something that teachers love when t...

Re: Help fix an SNES

>Would this cheap knockoff be responsible for this failure? Probably not. The higher voltage part damages the lower voltage part.

Re: snes ram dumping

Amelia The S-CPU is always driving the address bus. Any writes to in-console RAM or registers must be done with this CPU. You cannot cause the CPU to pause and tri-state its bus to do your own writes. The CPU drives the signals very strongly, and will burn up after a minute if you try to force oppos...

Damn cool seeing the triple 15-bit DAC of PPU2 in the upper left corner, and the 15-bit palette RAM in the bottom left corner.

As personally expected, the All-in-one chip is a lump of logic sausage squeezed around the earlier-tested handmade RAM blocks.
