## What works ## What works
Currently hardware implements basic functionality for playing games - ROM emulation, 4/16K EEPROM, bootloader and PC communication. You can send any ROM to the SDRAM from PC and if game doesn't check for save hardware other than EEPROM then it most likely will work. Bootloader does all the work necessary to setup the console registers for specific CIC chip that game requires.

You can send any ROM to the SDRAM from PC and if game doesn't check for save hardware other than EEPROM then it most likely will work. Bootloader does all the work necessary to setup the console registers for specific CIC chip that game requires.
## How to build
Instructions below are mostly written for Windows users and point to Windows specific executables.
1. Download latest zip files from [releases tab](https://github.com/Polprzewodnikowy/SummerCollection/releases).

19. Upload ROM by executing `UNFLoader -r your_rom_file.n64`
20. Turn on console and enjoy playing homebrew games on real hardware.
## Issues ## Issues
There are several issues with the project at the moment in order of importance: There are several issues with the project at the moment in order of importance. Keep in mind that core flashcart functionality is fully working:
- Documentation is not finished for most of the modules. - No debug interface for the [N64-UNFLoader](https://github.com/buu342/N64-UNFLoader).
- PCB schematic is unorganized and some component values are missing. - No read functionality through USB interface.
- There's no BOM for hardware. - No SRAM/FlashRAM save hardware implementation.
- Currently PC communication disables N64 PI interface completely as there's no bus arbiter implemented.
- No SD card interface hardware implementation. - No SD card interface hardware implementation.
- No save write-back to SD card hardware implementation. - No save write-back to SD card hardware implementation.
- PCB design and necessary components needs to be reconsidered for next version.
- No SRAM/FlashRAM save hardware implementation.
- No RTC hardware implementation. - No RTC hardware implementation.
- No CIC implementation in FPGA, current solution uses [UltraCIC II](https://github.com/perkinsb1024/UltraCIC-II) based on ATtiny45.
## What's next ## What's next
Current goal is to document the project. Current goal is to write debug module for the [N64-UNFLoader](https://github.com/buu342/N64-UNFLoader).

## PC communication
PC <-> Cart communication uses SPI as hardware layer. Communication is command based and PC is always responsible for transfer initiation.
Module contains two 1024 word (4 kB) FIFOs used as a gate between SPI clock domain and Cart clock domain. Debug communication uses its own set of FIFOs, 1 kB in size each.
### Commands
Every command starts with setting CS pin low, then sending command, writing and/or reading data and setting CS pin high. Only SPI mode 0 is supported.
#### Status (**0x00**)
Reads PC communication module status word.
Command bytes:
Byte(s) | 0 | 1:4
-----------|------|-------------
Value | 0x00 | Status word

Status word bits:
31:24 | 23 | 22 | 21:11 | 10:0
-------|-----------|-------------|------------|------------
ID | ADDR_INCR | N64_DISABLE | TX_FIFO_UW | RX_FIFO_UW

Byte(s) | 0 | 1:4
-----------|------|--------------
Value | 0x20 | Address word
Direction | W | W
Address word bits:
31:0 |
---------|
ADDRESS |
- Bits 31:0 **ADDRESS**: Starting address in bus address space.
Example - set starting address **`0x1034 5678`**:
Byte | 0 | 1 | 2 | 3 | 4
------|------|------|------|------|------
TX | 0x20 | 0x10 | 0x34 | 0x56 | 0x78
RX | x | x | x | x | x
*x = don't care*
#### Initiate read to RX FIFO (**0x30**)
Initiates read of X 4 byte (32 bit) words to RX FIFO. Maximum possible read length is 64 MB. However, it's possible to send multiple commands in series to achieve longer read lengths. After issuing this command it's necesarry to read data with "Read from RX FIFO (0x50)" command. Command will read dummy data when **N64_DISABLE** bit is cleared in communication module configuration.
This command consumes space in TX FIFO. Check TX FIFO availability before issuing this command.
Command bytes:
Byte(s) | 0 | 1:4
-----------|------|------------------
Value | 0x30 | Read length word
Direction | W | W
Read length word bits:
31:24 | 23:0 |
-------|-------------|
x | READ_LENGTH |
- Bits 31:24: Reserved. Writes are ignored but it's recommended to be set as 0 for future compatibility.
- Bits 23:0 **READ_LENGTH**: Number of words to be read to RX FIFO minus one.
Example - fill RX FIFO with 5 words (20 bytes):
Byte | 0 | 1 | 2 | 3 | 4
------|------|------|------|------|------
TX | 0x30 | 0x00 | 0x00 | 0x00 | 0x04
RX | x | x | x | x | x
*x = don't care*
#### Write to TX FIFO (**0x40**)
Writes data to TX FIFO. Sent words then are processed immediately as bus writes at current internal bus address. Data can be written only as 4 byte (32 bit) words. When **N64_DISABLE** bit in communication module configuration is cleared then command will process data in TX FIFO but it won't write anything to bus.
This command consumes space in TX FIFO. Check TX FIFO availability before issuing this command.
Command bytes:
Byte(s) | 0 | 1:4 | 5:8 | 9:12 | ...
-----------|------|-----------|-----------|-----------|-----

Byte | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8
------|------|------|------|------|------|------|------|------|------
TX | 0x40 | 0xDE | 0xAD | 0xBE | 0xEF | 0x01 | 0x02 | 0x03 | 0x04
RX | x | x | x | x | x | x | x | x | x
*x = don't care*
#### Read from RX FIFO (**0x50**)
Reads data from RX FIFO. Data can be read only as 4 byte (32 bit) words. Before reading it's necessary to check RX FIFO availability. Reading empty FIFO won't break anything but it's pointless.
Command bytes:
Byte(s) | 0 | 1:4 | 5:8 | 9:12 | ...
-----------|------|-----------|-----------|-----------|-----
Value | 0x50 | Data word | Data word | Data word | ...
Direction | W | R | R | R | ...
Data word bits:
31:0 |
------|
DATA |

Example - read 2 words (8 bytes) **`0xDEAD BEEF`**, **`0x0102 0304`** from RX FIFO:
Byte | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8
------|------|------|------|------|------|------|------|------|------
TX | 0x50 | x | x | x | x | x | x | x | x

-------|------------|------------
x | TX_FIFO_UB | RX_FIFO_UB
- Bits 31:22: Reserved. Reads as 0.
- Bits 21:11 **TX_FIFO_UB**: Number of bytes waiting to be processed by N64.
- Bits 10:0 **RX_FIFO_UB**: Number of bytes waiting to be read by PC.
Example - read debug FIFO status word:
Byte | 0 | 1 | 2 | 3 | 4
------|------|------|------|------|------
TX | 0x60 | x | x | x | x

# External code for SummerCart64 Firmware
This folder contains code downloaded directly from external repositories with minor modifications.
## qflexpress.v
### Source
[https://github.com/ZipCPU/qspiflash/blob/master/rtl/qflexpress.v](https://github.com/ZipCPU/qspiflash/blob/master/rtl/qflexpress.v)
### Documentation
There's [comprehensive documentation](https://zipcpu.com/blog/2019/03/27/qflexpress.html) for this module:
### Modifications
- Changed initialization sequence.
- Extended address space for 16-bit address alignment.
## wbsdram.v
### Source
[https://github.com/ZipCPU/arrowzip/blob/master/rtl/arrowzip/wbsdram.v](https://github.com/ZipCPU/arrowzip/blob/master/rtl/arrowzip/wbsdram.v)
### Modifications
- Changed refresh interval that suits 90 MHz clock and used SDRAM chip.
- Changed column and row address widths.
