| I made patches for SMB that make Mario always big, but never small, one that makes Mario start big when starting the game or after losing a life (like SMB2), and one that replaces coins with cherries (but requires a trained ROM). You can download the zipped Always Big patches here. Code Changed: (RAM addresses, not ROM addresses. To convert the RAM addresses into ROM addresses, subtract 7ff0 from the address.) $9061:A9 00* LDA #$00 (Originally 01) $9063:8D 57 07 STA $0757 $9066:8D 54 07 STA $0754 (Now Mario Starts Big) $9267:A9 00* LDA #$00 $9269:8D 54 07 STA $0754 $B260:AD 54 07 LDA $0754 = #$00 $B263:49 00* EOR #$00 $B265:8D 54 07 STA $0754 = #$00 You can download the zipped Start Big patch here. Code Changed: (RAM addresses, not ROM addresses. To convert the RAM addresses into ROM addresses, subtract 7ff0 from the address.) $85A3:A9 01* LDA #$01 $85A5:8D 56 07 STA $0756 (Mario starts big) $85B1:AD*56 07 LDA $0756 (I'm not really sure, maybe this prevented address $0756 to be changed from 01 to 00) $9061:A9 00* LDA #$00 $9063:8D 57 07 STA $0757 $9066:AD*54 07 LDA $0754 (Loads from $0757=00, so Mario won't die but shrink instead when he gets hit) $9267:A9 00* LDA #$00 $9269:8D 54 07 STA $0754 (Mario still just shrinks when he gets hit after death) You can download the Cherry patch here. You need to apply a trainer first. To do so, you can apply the IPS inside this ZIP file. Code Changed: (RAM addresses, not ROM addresses. To convert the RAM addresses into trained ROM addresses, subtract 7df0 from the address.) $BC12:C9 05* CMP #$05 $BC14: D0 0C BNE $BC22 $BC22:EA* NOP $BC23:EA* NOP $BC24:EA* NOP $BC25:EA* NOP $BC26:EA* NOP $BC16:A9 00 LDA #$00 $BC18:8D 5E 07 STA $075E=Coins $BC1B:20*00*70* JSR $7000 (Trainer=$7000-$7fff) $7000:A9 00 LDA #$00 $7002:8D ED 07 STA $07ED (Tens place of Mario's coins is reset to 00) $7005:8D EE 07 STA $07EE (Ones place, Mario) $7008:8D F3 07 STA $07F3 (tens, Luigi) $700B:8D F4 07 STA $07F4 (ones, Luigi) $700E:20 16 D8 JSR $D816 (Starman invisibility routine) $7011:60 RTS $BC1E:A9 20* LDA #$20 $BC20:85 FE STA $FE (Play power-up sound) Edit: Mod or Admin, please change the 2 in the thread title to a 3. Thank you. (edited by AP on 08-18-05 09:22 PM) |
