This will make it look much20 ;; cooler and create a terminal-like effect as the game is21 ;; being reprogramed. To do this, use a fixed data entry22 ;; region in ram, and run a program that translates this23 ;; region into the screen. Every time this data entry region24 ;; is full, run a program that copies the data to the25 ;; appropriate region in memory. This will cost ~15 seconds26 ;; at the beginning to set up, and then should have minimal27 ;; overhead (~5%) for the rest of the data transfer, but28 ;; will have a good psychological effect for the viewer29 ;; since he can see that something is actually happening in30 ;; the game.33 ;; Symbol size and type.35 ;; use fonts from zophar's domain:36 ;; http://www.zophar.net/utilities/fonts/8x8-font-archive.html38 ;; Green font on black background for matrix look.41 (defn program-data [base-address]42 (let [image-program43 (display-image-kernel44 base-address46 ;;pinkie-pie-mark47 test-image-color49 )52 music-base-address (+ (count image-program) base-address)54 initial-music-data55 (midi-bytes pony-csv 0 0 0 0)57 data-lengths58 (map (comp count :data)59 [(:kernel initial-music-data)60 (:voice-1 initial-music-data)61 (:voice-2 initial-music-data)]);; noise not needed62 addresses63 (map (partial + music-base-address) (reductions + 0 data-lengths))65 final-music-data66 (apply (partial midi-bytes pony-csv) addresses)68 music-program69 (concat70 (:data (:kernel final-music-data))71 (:data (:voice-1 final-music-data))72 (:data (:voice-2 final-music-data))73 (:data (:noise final-music-data)))]75 (concat76 image-program ;; image program falls through to music program78 (infinite-loop)79 ;;music-program81 )))86 (def glyphs87 "The sixteen 8x8 glyphs which make up the \"terminal\" font."88 (mapv #(ImageIO/read89 (File. user-home (str "proj/vba-clojure/font/" % ".png")))90 ["0" "1" "2" "3" "4" "5" "6" "7" "8" "9" "A" "B" "C" "D" "E" "F"]))92 (defn glyph-init-program93 [start-address]94 (let [zero-glyph (image->gb-image (glyphs 0))96 ;; write same pallet information to all pallettes97 A (flatten98 [(write-byte LCD-control-register 0x00);; disable LCD protection99 (set-palettes bg-palette-select bg-palette-data100 (repeat 8 (first (:palettes zero-glyph))))101 (select-LCD-bank 0)102 (write-byte SCX-register 0)103 (write-byte SCY-register 0)])104 B (flatten105 [(write-data106 (+ start-address (count A))107 character-data-address108 (flatten109 (map (comp gb-tile->bytes first :tiles image->gb-image)110 glyphs)))113 (write-byte114 LCD-control-register115 (Integer/parseInt116 (str117 "1" ;; LCDC on/off118 "0" ;; Window code area119 "0" ;; Windowing on?120 "1" ;; BG tile base (1 = 0x8000)121 "0" ;; BG-1 or BG-2 ?122 "0" ;; OBJ-block composition123 "0" ;; OBJ-on flag124 "1") ;; no-effect125 2))])]126 (concat A B )))130 (defn glyph-display-program131 [start-address132 max-glyphs]133 (let [data-start (+ 2 start-address)134 [max-glyphs-high max-glyphs-low]135 (disect-bytes-2 max-glyphs)136 load-data137 (flatten138 [;; data region139 0x18140 4141 0 0 ;; current num of glyphs-rendered142 0 0 ;; current row and column143 ;; save all registers144 0xC5 0xD5 0xE5 0xF5146 ;; load data from data region into registers148 0xF5 ;; push A149 0x21 ;; begin data load150 (reverse (disect-bytes-2 data-start))152 0x2A 0x47 ;; glyphs-rendered -> BC153 0x2A 0x4F155 0x16 max-glyphs-high ;; load max-glyphs156 0x1E max-glyphs-low ;; into DE157 ])159 handle-glyph-count*160 (flatten161 [;; if glyphs-rendered = max-glyph count, go directly162 ;; to stack-cleanup164 0x47 0xBA ;; compare B to D165 0x20 ;; skip next section B != D166 8 ;; this is equal to the number of instructions in the next167 ;; indented region!169 0x79 0xBB ;; compare C to E170 0x20 ;; JR NZ, skip if C != E171 4172 0xF1 ;; pop AF for stack maintainance!173 0x18174 :stack-cleanup-low175 :stack-cleanup-high176 ])178 display-glyph180 (let [init*181 (flatten182 [0xF1 ;; pop A, now A is equal to key input183 ;; BC is current number of glyphs rendered.184 ;; each glyph is two characters, and the screen can hold up185 ;; to 360 characters.
