My dear friend UncleTom bought a Type Zero PCB, and made the fundemental mistake of putting a BIOS V1.52 game on the system, when you do this - it renders the machine no longer to play older games (they will fail the new ID check security concept added),also this means people can no longer clone the drives. I asked if I could have a look at this PCB, and in 1day I've managed to develop a SSD solution and also I've repackaged the older BIOS games so they can boot on 1.52 BIOS machines!! They well then downgrade the BIOS (as the video demonstrates) - if you plug a 1.52 HDD it will update back to 1.52 again.

Tested on the following games::

Raizin Ping Pong VER 2.01 (2002/3/11 18:06:16) - English BIOS V1.52
Power Shovel VER 2.02 (1999/8/19 21:27:23) - English BIOS V1.11a
Battle Gear 2 VER 2.01J (2000/6/21 22:22:26) - Japan BIOS V1.52
Battle Gear VER 2.40A (1999/3/31 13:27:05) - English BIOS V1.11a
Landing High Japan VER 2.01 OK (1999/12/3) - English BIOS V1.52
