file : readme.txt author : rtw created: 2015-06-06 version: 1.1 Samba De Amigo Prototype USA, SEGA 1999, NAOMI Cart This prototype was provided by Arzeno Fabrice. Instead of an EPROM there is FLASH equivalent and the security chip is mounted in a socket. The PCB layout is very similar to Soul Surfer. The original ROM test showed that IC7 is bad. By comparing this dump with the US Dreamcast version MetalliC discovered that there was a 1 bit difference in the file OUT_RUN.ADX. This has been corrected and the dump is now error free. The dump has been verified against the ROM test signatures.
