 1. Remove the custom QFP144 CPU and replace it with a standard Hitachi HD6417095 SH-2 CPU
 2. Remove the 29F400 TSOP48 flashROM and re-program it with the decrypted and modified main program ROM from set
-   'cps3nobatt' in MAME. A 28F400 SOP44 flashROM can be used instead and mounted to the back side of the security cart
+   'cps3boot' in MAME. A 28F400 SOP44 flashROM can be used instead and mounted to the back side of the security cart
    PCB. Do not mount both SOP44 and TSOP48 flashROMs, use only one TSOP48 flashROM or one SOP44 flashROM.
 3. Power on the PCB and using the built-in cart flashROM menu re-program the SIMMs for your chosen game using the CD
-   from set 'cps3nobatt' in MAME.
+   from set 'cps3boot' in MAME.
 4. That is all. Enjoy your working PCB.
