New edit 6 (--checkrepaint, requires --e0thresh): hooks the CheckRequest
handler's final notify ($C5E4) through a 10-byte cave at $E020 that
repaints F0000000 after the self-test and re-renders the E0 readout only
when a counter is at/over threshold — no more stale 04000000 after
status checks. Candidate = 9600 native-game-compatible base + edits
1-2/5/6, 68 bytes vs stock, disassembly-verified, awaiting burn; on
verification it will be christened RIO 4.3.
All prior patched generations (wedge-only, 31250/31250v2, 62500/125000
science builds, e0t5 pair) moved to rio-firmware/archive/ with their
disassemblies; RIOv4_2.bin stays at top level as the pristine patch
source.
