The House Of The Dead Protection

using part of recently dumped prototype HOTD2 bios we was able to bypass Naomi bios checksumm protection!
that means region-free or any other customization is possible now.
also confirmed working on Sega System SP (AKA Aurora), Dreamcast on the way.
thanks to all who helped in testing on real hardware.

Are you afraid of Spiders ?

shortly: new system was reverse engineered and emulated - 'Sega System SP' codenamed 'Spider', in some sources (IMO mistakenly) called as "Sega Aurora".
probably last custom, not PC based, hardware developed by Sega.

Tech specs:
CPU: Hitachi SH4 HD6417091Y 200MHz + 32MB RAM
GPU/Chipset: PowerVR2 CLX2 AKA Holly + 16MB RAM
SPU: Yamaha AICA + 8MB RAM
NET: Au1500 333Mhz CPU + 2MB FlashROM + 8MB RAM (probably used only by satellite games)
Media: 128MB - 512MB reprogrammable FlashROM, Compact Flash.

side note: was developed dumping software which writes ROM board content to Compact Flash card, contact us if you have any undumped PCBs on this platform and you wish to dump its content.

Some screens of games dumped and emulated:

Tetris Giant / Tetris Dekaris




sadly, other dumped games for this platform requires RFID chips content to work, which we are not (yet) able to dump, so no great pictures yet..

Dinosaur King - Operation: Dinosaur Rescue (USA, Export) (System SP) found and dumped by Hamster

this is second game in DinoKing series, it was followed by one more (unknown for me) part and later by 'D-Team VS. the Alpha Fortress' AKA 'Ver 2.500'.
please let me know if you know something about that unknown game part, or any of Japanese releases of DinoKing and other trading card game series like Mushiking for Naomi or SP/Aurora platforms! its really hard to find something about such type games releases/versions in the net.
