The Web 6502 IDE is a continuation of the many fine 6502 emulators available on the web today, but it uses modern browser features to combine some of the best pieces of software available today.
This first release has all of the features of the well-respected site 6502asm.com.
However, the source code is not 100% compatible between the two, but the changes needed are quite minor. I have copied all of the examples from that site and have included them with this release.
I enjoy retro computing and the simplicity of the old 8bit machines. I wanted a sandboxed environment to explore in and show off my creations.
However, I found that all of the web-based 6502 assemblers were
usable, but lacked a lot of modern features I had gotten used to
with dasm. I figured I could either spent a few weeks adding
these features, or I could spent the time learn to use emscripten
and interfaing with wasm.
- Save! Yes, I want to be able to save the code I am working on. Save to browser storage with the chance to download my library a a
zipfile. - Add text output. Set aside some memory as a frame buffer and let text I/O working. Then I'd like to port one of the versions of BASIC over.
- Convert it to an application using Electron or some similiar tool.
- Atari 2600 emulator. Code and deploy directly to an Atari 2600 machine. I may consider other 6502 based machines if they are available.
Under the hood, there are several pieces of software which makes this all possible.
- emsciopten is a C and C++ compiler that can target both JavaScript and Web Assembly (WASM). This package was vital in porting the assembler and the 6502 emulator to the web.
- dasm is an assembler that has been around for many years now and can target the 6502 microprocessor.
- fake6502 is a freely available 6502 emulator that has been well tested in a number of emulation projects.
- CodeMirror is a JavaScript based editor with many features far, far beyond a normal
textareaelement.
