Squeezing Part II

Let's start with the sound effects.

The game uses 23 sounds effects, let's have a look at them with Audacity.

• sample1.wav: 8,000 Hz 9,250 bytes 8 bits
• sample2.wav: 11,025 Hz 10,803 bytes 8 bits
• sample3.wav: 11,025 Hz 9,257 bytes 8 bits
• sample4.wav: 11,025 Hz 2,192 bytes 8 bits
• sample5.wav: 22,050 Hz 31,364 bytes 16bits
• sample6.wav: 11,025 Hz 7,834 bytes 8 bits
• sample7.wav: 11,025 Hz 6,807 bytes 8 bits
• sample8.wav: 11,025 Hz 4,442 bytes 8 bits
• sample9.wav: 11,025 Hz 7,436 bytes 8 bits
• sample10.wav: 11,025 Hz 4,535 bytes 8 bits
• sample11.wav: 11,025 Hz 6,834 bytes 8 bits
• sample12.wav: 22,050 Hz 14,040 bytes 8 bits
• sample13.wav: 11,025 Hz 6,925 bytes 8 bits
• sample14.wav: 11,025 Hz 17,407 bytes 8 bits
• sample15.wav: 11,025 Hz 1,922 bytes 8 bits
• sample16.wav: 11,025 Hz 5,409 bytes 8 bits
• sample17.wav: 11,025 Hz 3,288 bytes 8 bits
• sample18.wav: 8,000 Hz 14,460 bytes 8 bits
• sample19.wav: 22,050 Hz 20,748 bytes 8 bits
• sample20.wav: 11,025 Hz 20,876 bytes 8 bits
• sample21.wav: 11,025 Hz 15,898 bytes 8 bits
• sample22.wav: 22,050 Hz 14,444 bytes 8 bits
• sample23.wav: 11,050 Hz 16,110 bytes 16 bits

That's 252,269 bytes for the sounds effects.

As you can see, each sample has different resolution and frequency, this is quite common with home-brew games. I'll convert all of them to a 8bits 8,000Hz, signed sample. Maybe I can use a higher frequency if I've some free space to improve the sound quality. 

After conversion and packing the data I've 87,730 bytes, that's 34,7% of the original space or 65,3% space saved. If I need some extra space I'll use ADPCM encoding to reduce each sample to a 50% before compression.

I still have some issues to fix, also I need some feedback from NTSC users.

Squeezing Part I

Here I'm going to comment the development of a new Atari Jaguar game.  It's a project that I got in mind from a long time ago.

The game it's not original, it's a conversion from other platform, I have all the assets and the source code that needs to be rewritten because it's not C.

The biggest issue it's that the folder with the executable, graphics and sounds takes 10,7 MB, 10,559,675 bytes to be precise, remember that the all graphics asserts are packed.

The game must fit into a 4MB cartridge, without dropping any sound, music or graphics.
