MAME Info:

0.95u4 [David Haywood, f205v]


- 0.135u3: David Haywood identified Semicom's Dream World hardware as a copy of Psikyo's 68020 hardware (it was already known that their older platforms were copied from Snow Bros and Tumble Pop).

- 0.135u2: Fabio Priuli added save state support to Dream World.

- 0.128u2: Stephane Humbert fixed dipswitches and inputs for Dream World. Added dipswitches 'Lives' and 9x 'Unused'.

- 0.111u6: David Haywood and Guru fixed clocks and other details in Dream World based on new measurements. Changed VSync to 58Hz.

- 0.111u5: Added 2x OKI6295 (1MHz) stereo sound, the Philips 8752 MCU protection data rom and dipswitches 'Lives', 'Ticket Payout', 'Free Play', 'Demo Sounds', 'Coinage', 'Difficulty' and 'Service Mode'.

- 24th December 2006: David Haywood - Dream World by Semicom is now working... The hardware is rather different to that used by most Semicom games. It uses a 68020 instead of a 68000 and has different video hardware too.

- 22nd August 2005: Guru - Dream World for trojaning received in a package from the good boys at the Italian MAME.

- 0.97u1: David Haywood improved protecton in Dream World - still not working. The protection data is read via a port, scrambled a bit, and put in main ram and the interrupt is pointed to the data in ram. Changed visible area to 304x224. Added dipswitches '0', '1', '2' and 29x 'Unknown'.

- 0.96: Some improvements to Dream World [David Haywood]. Changed visible area to 512x512. Swapped gfx3 roms.
