Development and Debugging Suite for the C256 Foenix Family of Computers.
This project is derived from the Nu64 emulator built by Tom Wilson. Nu64 is owned by Tom Wilson. FoenixIDE is owned by the C256 team, led by Stefany Allaire. You need to use Microsoft Visual Studio 2019 to compile/build this project.
The FoenixIDE emulates the WDC 65816 and 6502 processors. It is intended to be used as a software development tool and learning platform for assembly language and BASIC programming. The software will be relesed with an open source license and may be used for whatever purpose you want, including personal projects, education, and commercial use.
The C256 is loosely based around the concept of the world's most popular computer, the Commodore 64. When you turn on the system, you see a BASIC screen, with the READY prompt. You can type in BASIC commands, enter programs, or load programs from disk, tape or cartridge.
The FoenixIDE attempt to replicate this experience on a modern computer: you will be able to write and run BASIC programs, 65816 assembler programs, and save programs to disk to trade with other people. The Nu64 will feature an 80 column text screen, several different graphic resolutions, and the ability to communicate with hardware and other computers through a virtual modem.

The FoenixIDE is a work in progress.
The C256 Foenix and its associated materials are owned by Stefany Allaire. There are several versions of the Foenix:
- RevB (2 MB RAM, 2xOPL2) - Processor: 65816
- RevC - aka FMX (4 MB RAM, OPL3, OPN2, OPM and SN76489) - Processor: 65816
- RevU - 1 MB RAM - Processor: 65816
- RevU+ - 2 MB RAM - Processor: 65816
- RevJr - 1 MB RAM - Processor: 6502
- RevJr65816 - 1 MB RAM - Processor: 65816
- RevK - 1MB RAM - Processor: 6502
- RevK65816 - 1MB RAM - Processor: 65816
The FoenixIDE looks for kernel.hex and kernel.lst files in the ROMs folder colocated with the executable.
Obtain the Kernel from the sister repository: https://github.com/Trinity-11/Kernel_FMX
For the F256Ks, the kernel is specified in bulk.csv with references to 8KB files. See here: https://github.com/FoenixRetro/f256-firmware
- Shift+F11 - toggle fullscreen
- Shift+F5 - Run, or Pause in the debugger Other keyboard activity is forwarded to the emulated C256 itself.
- F5 - Run
- F6 - Step (Execute a single opcode)
- F7 - Step Over (Execute a subroutine until RTS/RTL. Also applies to loops, until the next command is reached)
- Page Up/Page Down - display the next page (256 bytes) of memory.
