True 480i/576i ASCAL scaler output over direct_video

Context

The MiSTer board is used with direct_video=1 (realtime analog video via HDMI DAC). Cores with native interlaced output (Minimig) produce true 480i on a CRT, but cores that only output 480p (ao486) cannot. Goal: patch the ASCAL scaler so it can render any core's video (and the Linux/menu framebuffer) as true interlaced 480i/576i — alternating 262/263-line (312/313 PAL) fields with a half-line vsync offset — delivered over the direct_video HDMI pins, giving ~480 visible NTSC lines.

Two features, per user decisions:

1. vga_scaler=1 + direct_video=1 together routes the ASCAL output to the HDMI/DV pins for game cores (today only cores hardwiring VGA_SCALER=1, like ao486, get this). Works with unmodified core bitstreams — it's pure Linux-side routing via the existing CONF_VGA_FB mux (production-tested path, sys_top.v:1317-1320).
2. New ini key DIRECT_VIDEO_INTERLACE=1: the DV scaler mode becomes true 480i (576i when `ME

Collaborating with Claude Code

This guide distills patterns from hundreds of successful AI-assisted development sessions. The core insight: you're not "prompting" a tool, you're collaborating with a knowledgeable partner who happens to have no memory of yesterday.

Mindset Shift

Stop thinking: "How do I get the AI to produce the right output?" Start thinking: "How do I collaborate with a senior developer who has amnesia?"

This reframe changes everything. You wouldn't give a colleague a vague task and hope for the best. You'd share context, explain your reasoning, discuss tradeoffs, and work together toward a solution.
