NerdOfEpic: /* NerdSembler */

The NerdConsole project is a monstrously large hobby project being done entirely by one person. That means a lot to do, a lot to learn, and a lot of things to make work together. It also means that at any given time I may be working on any number of different parts of the project. To help make it as straightforward as possible to figure out what's going on, this page presents a high level list of activities.

== PPU Software ==

* '''(In Progress)''' Rewriting the PPU software from scratch. Previously the PPU was written in Java, but I kept running into issues caused by the language design. Specifically the extra work caused by the lack of unsigned data types. I'm rewriting it in C++, but not just for access to unsigned integer types. It was also the most straightforward way to get access to proper libraries for graphics (SDL3 - Simple DirectMedia Layer 3.0) and GPIO (libgpiod).
** I tried creating unions to allow for bytewise setting of complex register and table types with useful access to sub-values. This ended up not working because the level of control available when creating unions and the ways the compiler does automatic bit packing caused impossible data arrangements.
** Instead I made a collection of POCOs that do this job, but I won't deny I was hoping to not have to.

== PCB Work ==
* Need to redesign the Video Logic Level board to put the pins in a new order. This was the realization that GPIO pins are not logically ordered in a sane way that lines up with the physical layout. As it turns out, the way I was doing this was going to result in massively inefficient value loading that required a ton of bit shifting and masking and simply putting things in a different order improved this situation a ton.
* Need to come up with a solution for YM-3812 FM Synthesizer chips being either expensive or fake (or both). My current theory is a software based approach that runs on a RP2040 (Raspberry Pi Pico) and emulates the YM-3812, or some other audio solution built into the PPU program. The hope is that the emulated audio solution is as close to a drop in replacement for the YM-3812 as possible, but I'm not guessing the standard YM-2014 DAC will work so another solution will probably be required. This change requires spatial changes due to differences in DAC, amplification, and chip size difference between Pi Pico and YM-3812. A PPU emulated approach would require remapping the PPU pins again, which I would like to avoid.
* Need to redesign the Main Board since so many things have changed in the plan since the last time I ordered boards. Prototype 2 is an almost complete redesign.
** The Raspberry Pi was changed to be a full sized Raspberry Pi 4 instead of the smaller Raspberry Pi 3A+.
** The cartridge connector was changed for one with a smaller pin pitch (2.54mm instead of 3.96mm) to make inserting and removing cartridges easier. This obviously changed the entire middle of the board.
** The User Port support was removed entirely. This means the removal of the VIA chip and several supporting chips for interrupt control, as well as expansion headers on the main board and the external DB-25 connector.
** Optional extra controller ports are now supported (to better use the bus lanes available on the joystick buffer). This means additional connectors need to be available to support that.

== 3D Modelling ==
* Need to design several case parts. These are fairly self explanatory but also depend on how various PCBs end up looking.

== Other Software ==
=== NerdSembler ===
* I hope to one day be able to get my brain around making an assembler for the 65xx family of CPUs. I'd already written the lexer and part of the parser when I ran into difficulties with parsing complex expressions that would be very handy to support.
* I started coding NerdSembler in Java, but similar to the PPU project I was running into problems with Java and started over from scratch in C++. I've gotten the lexer and several parts of the abstract syntax tree and parser working. Next is the emitter.

=== Graphics Tiles ===
* I have written a tool that uses standard .png files to produce binary graphical tile data. This tool will need to be revisited to support other binary representations and to have better documentation.

NerdSembler

2024-11-30T00:14:32Z

NerdOfEpic: /* How does NerdSembler work? */

== What is an assembler? ==
An assembler is a tool that produces machine code from source code files that are written in assembly language. Assembly language is pretty similar to machine code since assembly instructions map essentially one to one to machine instructions.

== Why use an assembler? ==
Assemblers offer conveniences to programmers by providing features like labels for branch and jump instructions. The use of dynamic labels prevents the need for hard coded jump targets that can move if an extra instruction is inserted into the code.

== How does NerdSembler work? ==
NerdSembler uses a phased approach to assembling code. Each phase takes data in some form and passes it through an algorithm that converts it into another form. After several phases, the source code written by the developer is finally converted all the way to machine code.

NerdOfEpic: /* How does NerdSembler work? */

== What is an assembler? ==
An assembler is a tool that produces machine code from source code files that are written in assembly language. Assembly language is pretty similar to machine code since assembly instructions map essentially one to one to machine instructions.

== Why use an assembler? ==
Assemblers offer conveniences to programmers by providing features like labels for branch and jump instructions. The use of dynamic labels prevents the need for hard coded jump targets that can move if an extra instruction is inserted into the code.

== How does NerdSembler work? ==
NerdSembler uses a phased approach to assembling code. Each phase takes data in some form and passes it through an algorithm that converts it into another form. After several phases, the source code written by the developer is finally converted all the way to machine code.

NerdOfEpic: /* Want other Information? */

== Welcome to the NerdConsole Wiki. ==

With any luck the information here will be able to answer all your questions. It is recommended that you search for the information you are looking for with the search box to the left. Good luck and have fun!

NerdConsole is an 8-bit game console designed from scratch. It was designed to provide powerful features and to make using them as easy as possible for game developers. There are no licenses, security or regional lockouts so anyone that wants to make a game can jump in and do so.

It is a 65C02 CPU based game console that was inspired by some of the design decisions made by Nintendo for the NES but it is NOT an emulator and it is NOT directly compatible with the NES. It may be difficult, but it should be possible to port games from other 6502 based machines to NerdConsole if that is what you are interested in doing.

This project is the multi-year hobby project of a single person, so please be gentle about how long it's taking me to finish it. There are a lot of things to learn and to do, and I work a full-time job.

Head over to the [[Project Status]] page for more details about what is going on right now.

=== Need Specifications? ===
* [[Memory Regions]] for where data lives within NerdConsole.
* [[Control Page]] for the available registers that control NerdConsole.
* [[Graphics Modes]] to see all the ways you can configure your graphics.
* [[Built-In Palette List]] for the collection of palettes that can be used if you don't want to make your own.
* [[Palette Formats]] to understand how the bits work when setting up colors.
* [[Tile Formats]] for how to arrange data into graphics.
* [[Name Tables]] for how to assemble graphics tiles into backgrounds.
* [[Sprite Table]] for how to use graphics tiles for moving foreground objects.
* [[Connectors]] for how various things connect within the system.
* [[Joysticks]] for how to deal with user input.
* [[Integrated Circuit Chips]] for how the various chips work.

=== Want other Information? ===
* [[Glossary]] for terms and acronyms that you may not know.
* [[Downloads]] to get NerdConsole files.
* [[Assembly Language]] for a collection of helpful pieces of code you can use in your own projects.
* [[Specification Comparison]] between NES and NerdConsole.
* [[Console Versions]] to read about how there used to be both standard and development editions.
* [[Development Language]] for details about why the NerdConsole PPU is being rewritten.
* [[Licenses]] for information about how things are allowed to be used.
* [[Other Tools]] for helpful other programs that might be useful when making games.

The NerdConsole project is a monstrously large hobby project being done entirely by one person. That means a lot to do, a lot to learn, and a lot of things to make work together. It also means that at any given time I may be working on any number of different parts of the project. To help make it as straightforward as possible to figure out what's going on, this page presents a high level list of activities.

== PPU Software ==

* '''(In Progress)''' Rewriting the PPU software from scratch. Previously the PPU was written in Java, but I kept running into issues caused by the language design. I'm rewriting it in C++ so I have access to unsigned integer types and proper libraries for graphics and GPIO.
** Creating unions to allow for bytewise setting of complex register and table types.
** Writing tests to make sure they work properly.

== PCB Work ==
* Need to redesign the Video Logic Level board to put the pins in the new order. This was the realization that GPIO pins are not logically ordered in a sane way that lines up with the physical layout and the way I was doing this was going to result in massively inefficient value loading that required a ton of bit shifting and masking.
* Need to come up with a solution for YM-3812 FM Synthesizer chips being either expensive or fake (or both). My current theory is a software based approach that runs on a RP2040 (Raspberry Pi Pico) and emulates the YM-3812. The hope is that the emulated audio solution is as close to a drop in replacement as possible, but I'm not guessing the standard YM-2014 DAC will work so another solution will probably be required. This change requires spatial changes due to differences in DAC, amplification, and chip size difference between Pi Pico and YM-3812.
* Need to redesign the Main Board since so many things have changed in the plan since the last time I ordered boards. Prototype 2 is an almost complete redesign.
** The Raspberry Pi was changed to be a full sized Raspberry Pi 4 instead of the smaller Raspberry Pi 3A+.
** The cartridge connector was changed for one with a smaller pin pitch (2.54mm instead of 3.96mm) to make inserting and removing cartridges easier. This obviously changed the entire middle of the board.
** User Port support was removed entirely. This means the removal of the VIA chip and several supporting chips as well as expansion headers and the DB-25 connector.
** Optional extra controller ports are now supported (to better use the bus lanes available on the controller buffer). This means additional connectors need to be available to support that.

== 3D Modelling ==
* Need to design several case parts. These are fairly self explanatory but also depend on how various PCBs end up looking.
** Main Case
*** Bottom
*** Top
*** Cartridge Guide
*** Switch and Button Adapters
*** Video Board Supports
** Cartridge Case
*** Bottom
*** Top
** Extra Controllers Breakout
*** Bottom
*** Top

== Other Software ==
=== NerdSembler ===
* I hope to one day be able to get my brain around making an assembler for the 65xx family of CPUs. I'd already written the lexer and part of the parser when I ran into difficulties with parsing complex expressions that would be very handy to support.
=== Graphics Tiles ===
* I have written a tool that uses standard .png files to produce binary graphical tile data. This tool will need to be revisited to support other binary representations and to have better documentation.
