Thanks for all the helpful insights, everyone! I've now got the name table data down to 124 bytes, a whopping 87.08% compression! @Roth: We should trademark that. It's all about Hella Compression™. @Celius: Your idea of decomposing the title screen into rectangular regions worked beautifully! @teppl...

Okay, here's what I've got so far: There are 4 encoding modes, which are determined by bits 7-6. They are described below. Immediate Mode: %00xxxxxx; x = tile index This mode is used for sequences of tiles whose indices are random but lie in the range [0, 63]. This allows storage of multiple literal...

Title screen name table compression

Right now the name table for my game's title screen is uncompressed (960 bytes), and I'm looking for a good algorithm to reduce its size. The title is drawn at a perspective, kind of like the Mega Man games. I mention this to give you guys a sense of how much tile repetition occurs (not a whole lot)...

Welcome, When I first got started, the first thing I did was read every document I could find on this website. There's so much information here; it's truly amazing.

Generating different instruments on the APU

Greetings everyone, I'm currently writing the sound engine for my NES game, and was wondering how to implement different instruments. I'm no musician, but I have a decent (not expert) understanding of the physics of sound. A friend of mine is composing MIDI files on his Mac, which I then convert to ...
