SHADOW additional notes: - the intro is released on a standard DOS 3.3 image file. - the "HELLO" file (who doesn't actually use that name) only RUNs two command: HOME and CATALOG. - the catalog display is customized to display information about intro. - SHADOW is a standard binary file: two sectors are occupied on the disk, one for the data itself (actually half a sector) and another one with the DOS 3.3 tracks and sectors list for the file. - Do not try to write another file on this DSK, VTOC table is also customized (tagged!) and does not represent actual disk sector usage! - Full code (extracted with Ciderpress): 0060- 20 E2 F3 JSR $F3E2 0063- 20 40 FB JSR $FB40 F8ROM:SETGR 0066- A9 06 LDA #$06 0068- 69 07 ADC #$07 006A- 20 47 F8 JSR $F847 F8ROM:GBASCALC 006D- A9 55 LDA #$55 006F- A0 23 LDY #$23 0071- A2 07 LDX #$07 0073- 46 DF LSR $DF 0075- 90 02 BCC $0079 0077- 91 26 STA ($26),Y 0079- 88 DEY 007A- CA DEX 007B- 10 F6 BPL $0073 007D- C6 74 DEC $74 007F- C0 03 CPY #$03 0081- D0 EE BNE $0071 0083- C6 67 DEC $67 0085- 10 DF BPL $0066 0087- A0 00 LDY #$00 0089- A2 FF LDX #$FF 008B- 8D 56 C0 STA $C056 rw:LORES 008E- 50 03 BVC $0093 0090- EA NOP 0091- EA NOP 0092- EA NOP 0093- EA NOP 0094- 0E 57 C0 ASL $C057 rw:HIRES 0097- 50 00 BVC $0099 0099- A1 AC LDA ($AC,X) 009B- 8D 30 C0 STA $C030 rw:SPKR 009E- CA DEX 009F- D0 EA BNE $008B 00A1- 88 DEY 00A2- D0 E5 BNE $0089 00A4- C6 8F DEC $8F 00A6- 10 E1 BPL $0089 00A8- A2 50 LDX #$50 00AA- AD 19 C0 LDA $C019 r:RDVBLBAR 00AD- 10 FB BPL $00AA 00AF- B9 56 C0 LDA $C056,Y 00B2- A9 44 LDA #$44 00B4- 20 A8 FC JSR $FCA8 F8ROM:WAIT 00B7- 98 TYA 00B8- 49 01 EOR #$01 00BA- A8 TAY 00BB- 8D 30 C0 STA $C030 rw:SPKR 00BE- CA DEX 00BF- D0 E9 BNE $00AA 00C1- 4C 84 9D JMP $9D84 00C4- 7A 00C5- 5E 17 A2 00C8- 4A 00C9- 52 14 00CB- A2 42 00CD- 52 14 00CF- A2 7B 00D1- DE F4 AA 00D4- 0A 00D5- 52 94 00D7- AA 00D8- 4A 00D9- 52 94 00DB- AA 00DC- 7A 00DD- 52 F7 00DF- BE
