Re: MMC1 MAPPER impossible to do with discrete parts

The problem with it is that you'd need an absurdly high amount of gates to get just the shift logic to work 100% identital to the MMC1.

Using a programmable logic PAL I was able to replicate MMC1's functionality with 3 chips only.

Re: Commodore 64 external hardware acceleration of smooth scrolling?

One suggestion was that it contains "pre-shifted" copies of graphics. This in turn got me thinking about background scrolling on the C64. I'm unsure how you'd do that. A graphic tile can be pre-shifted, that's for sure, but then you have to pre-shift it's neighbour into it as well to make...

Re: Montezuma's Revenge for the NES

Congratulations on this great achievement ! I remember my brother playing this on the C64 when I was a kid. I liked the game. Great to see this coming to the NES. Even though the graphics could probably be improved to be more NES-like. I think you did great with the animation system, it should have ...

Re: Is the Internet has more accuracy SPC rips?

I guess everyone makes errors, no matter how stupied they are. I cheked it up, and the rip that sits on my PC since 2003 is well and in stereo :)

For the rest I fear the rips are just copied across various sources and so if there is any error in any package it's unfortunately repeated.

Re: nocash discussion

I would say that they added a bunch of extra junk that you don't need after Windows 98. Especially the interface of Windows XP became very bloated and plastic looking. Though you could still revert to the classic style at that time, I can see where you don't want or need that extra junk in there. T...

Re: Have you seen such a video mode?

I am not sure I understand what you ask. Basically you suggest a tiled mode, where the individual pixels are easier to adress (without the bit shifts usually necessary in such cases) so it is easier to simulate a bitmap mode ? And that results that the annoying adress bit shiftings have to be done w...

Re: What would you change about the NES?

I already started the same thread in 2006. My answer wouldn't change since then, that is, 16x8 sprites instead of 8x16 sounds like a better idea, especially if it can still put 8 sprites that are twice as wide. Another great change would have to have the PAL NES more compatible with the original NT...

Re: A guide to change Mega Man sound effects?

Capcom has had two major sound engines which are incompatible with eachother, the "old" sound engine being used in Mega Man and Mega Man 2, and the "new" one in Mega Man 3 to Mega Man 4. You should start to learn how each of the sound engine works and how their data is stored : h...

Re: Simulating 75% and 87.5% pulse wave in MIDI

It's also useful for chiptunes on a sound chip with only 50% square waves, like a Master System. Indeed, but there needs to be a precise volume control. When I've done NES MIDI, I've typically used the sawtooth instrument in order to approximate the 75% duty cycle pulse wave - it doesn't sound exac...

Simulating 75% and 87.5% pulse wave in MIDI

General MIDI sounds contains few means to generate basic waves : Square wave instrument #80 Saw wave instrument #81 Ocarina instrument #79 is de-facto close to sine wave on most synths Unfortunately, the square and saw waves of those set is usually played with some chorous effect and some filtering,...

Re: Capturing YM2413 patches from Yamaha PSS-140 for potential use with VRC7

Also, there's already a freely-distributed set of General MIDI OPL2 patches as part of ALSA ("std.sb") and I wouldn't be surprised if a lot of the OPLL patches that have been found above correspond. I'll try to build a tool to check this in a couple days. Amazing, when I was a kid I spent...

Re: Stop byuu/near

Because the thread was first posted while Near was still alive, and it was a call to stop an active suicide. But is there any evidence that the person behind Near actually did this, and if so, what could we do about it anyway ? Just for the record, an online account not responding to messages or no...
