@sid6581

The emulator uses just a single core out of eight. The sample rate could have been greatly improved if more cogs were used. SIDcog has got a sample rate of 985248>>5 = 30789 Hz for PAL and 1022727>>5 = 31960 Hz for NTSC emulation. The most cycle hungry part of the emulation is, of cours...

MM Arduino NES Controller

I reverse engineered an Nintendo controller so that I could use an Arduino to control my NES.

MrAhle2 commented:

Emulating a standard shift register doesn't need something as "powerful" as an arduino(ATmega328). Any 8bit, 1$ mcu with less than 1k of code memory and at least 12 gpio will do! Like the "PIC16F54".

Nice project though!

@PJBonoVox

It certainly is one of the very best oldschool amiga demo tunes.

However, In my opinoin the second tune in "Voyager" by "Razor 1911" is the greatest tune from ANY oldschool Amiga demo. (even better than "Enigma" by "Phenomena")

MrAhle2 commented:

@karadok666

But, that doesn't change the fact that the STe has to do module playback in software.

For module playback in hardware the following must be true.

- Sound hardware must have at least 4 independent sample channels

- Each channel must be able to play at an arbitrary sample frequency

Comparing the clock rate of a modern PC to the Mc68000 doesn't give you an accurate comparison at all.

Actually, the Amiga has got special hardware for doing "raster tricks", which is the heart of any good "Outrun clone". Have a look at "Lotus 1/2/3", "Jaguar xj 220", "Vroom", "Prime Mover" for games that actually uses the copper chip in the Amiga.

Nice to see some progress. :)

Some questions:

1. Do you use the SIDcog API or do you write directly to the memory mapped registers?

2. The speaker does not look like a full range speaker; Do you intend to add a tweeter?

3. How will you mix the outputs from the different SIDcog instances?
