RetroBASIC Coach

An AI tutor that lives inside online retro coding IDEs (C64, BBC Micro, ZX Spectrum) and walks hobbyists through the weird quirks of 8-bit BASIC — like the two-letter variable limit, tokenized keywords eating variable names, and POKE timing — with challenges that get harder as you improve.

Target user

hobbyists learning retro programming on C64, BBC Micro, Spectrum and other 8-bit machines

Features
  • Quirk-aware hints that recognize classic BASIC traps (variable name collisions, INPUT vs GET, tokenized keywords) and explain them in plain English before the learner gets stuck
  • Progressive challenge path: 'Make the goblin move' → 'Make the goblin chase you' → 'Add a d20 combat roll', each tied to a working retro project in-browser
  • Side-by-side mode that shows the same program in 6502 assembly and BASIC so the learner sees what's actually happening on the metal
  • Personal retro project journal that compiles the learner's games into a shareable gallery inside the retro community site
Why now

The C64 dungeon crawler article highlights exactly the kinds of non-obvious traps (two-letter variable names, INPUT vs GET) that kill beginners; an AI tutor that knows these specific quirks removes the single biggest friction in retro programming education.

Demand
3/10

Retro BASIC hobbyist community is real (Lemon64 forums, Retro Game Coders, 8bitworkshop users) but small; the cited HN C64 dungeon-crawler post got only 10 points and 0 comments, signaling limited mainstream interest.C64 Basic Dungeon Crawler: Goblin Attack (C64 Basic Part 8) on Hacker News

Whitespace
4/10

RetroCode by Senzall is a direct competitor — free desktop IDE with BASIC V2.0 mode, 25 BASIC lessons, 50+ samples, and AI integration via Claude/Ollama/Copilot; 8bitworkshop and Retro Game Coders also cover the space with established free content.RetroCode v1.4.0 — Assembly, BASIC & 25 Languages with AI8bitworkshopRetro Game Coders

Monetization
3/10

RetroCode is explicitly 'Free to download and use. No account required,' and 8bitworkshop is also free; retro programming education is dominated by free blogs, YouTube channels, and forums, with hobbyists showing low willingness to pay in this niche.RetroCode v1.4.0 — Assembly, BASIC & 25 Languages with AI8bitworkshop

Longevity
7/10

Retro 8-bit hardware and its enthusiast community have been stable for decades with no churn risk; platforms like 8bitworkshop have persisted for years, indicating durable niche demand.8bitworkshop

Feasibility
7/10

RetroCode proves the stack — BASIC interpreter + LLM chat integration + lesson authoring — is straightforward to assemble; an LLM with curated retro BASIC knowledge plus a challenge generator is a moderate-build project, not trivial but well within reach.RetroCode v1.4.0 — Assembly, BASIC & 25 Languages with AI
