Effect columns: the first six raise the six current externals, in order Start, Corner, Out of Box, Competing, Tenacious and Spurt (the game's feeding code in all four versions, read twice independently; see the FAQ). No food raises speed, stamina or sharp directly, and in the game each gain shrinks as the six externals add up (full under 240, half from 280). The seventh column (Size, 1 only on Large Pudding and Large Banana) and the Cls Feed/Growth flag only change how the food is drawn on screen. Edit any cell (0–255). Enable Beer = +2 to DRAFT & +4 to BLACK across the six externals (the KOREAN-GINSENG template; the same 12-byte change as the original beer experiment). World Edition (Rev C and Rev D) never offers beer in the feed menu, so a patched beer does not appear there; DOC 2000 offers it only at exactly 14 races, after a Perfect in that session's training, and only if the horse holds at least one of three particular G1 titles. Index stays in the 1–39 range (out-of-range crashes the cabinet). Edited rows turn green; beer rows are amber.
